Salvia divinorum (also known as Diviner's Sage,[17] Ska María Pastora,[18] Seer's Sage,[19] and by its genus name Salvia) is a psychoactive plant which can induce dissociative effects and is a potent producer of "visions" and other hallucinatory experiences. Its native habitat is in cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady and moist locations.[20][21] The plant grows to over a meter high,[16] has hollow square stems, large leaves, and occasional white flowers with violet calyxes. Botanists have not determined whether Salvia divinorum is a cultigen or a hybrid; native plants reproduce vegetatively, rarely producing viable seed.[22][23]

Mazatec shamans have a long and continuous tradition of religious use of Salvia divinorum, using it to facilitate visionary states of consciousness during spiritual healing sessions.[16] Most of the plant's local common names allude to the Mazatec belief that the plant is an incarnation of the Virgin Mary, with its ritual use also invoking that relationship. Its chief active psychoactive constituent is a structurally unique diterpenoid called salvinorin A,[24][25] a potent κ-opioid and D2 receptor agonist.[26][27] Salvia divinorum is generally understood to be of low toxicity (high LD50)[28][29] and low addictive potential[26][30] since it is a κ-opioid agonist and a great deal of research has indicated that κ-opioid agonist activation of the kappa opioid receptor as shown by salvia may, in fact, serve as a potent addiction treatment therapy.[31]

Salvia divinorum remains legal in most countries and, within the United States, is legal in the majority of states. However, some have called for its prohibition. While not currently regulated by US federal drug laws, several states have passed laws criminalizing the substance.[32] Some proposed state bills have failed to progress and have not been made into law (with motions having been voted down or otherwise dying in committee stages). There have not been many publicized prosecutions of individuals violating anti-salvia laws in the few countries and states in which it has been made illegal.[nb 1]

History

Salvia divinorum is native to the Sierra Mazateca in Oaxaca, Mexico, where it is still used by the Mazatec, primarily to facilitate shamanic visions in the context of curing or divination. S. divinorum is one of several species with hallucinogenic properties that are ritually used by Mazatec shamans. Others include certain morning glory seeds (Turbina corymbosa), psilocybin mushrooms, and various coleus species. In their rituals, the shamans use only fresh S. divinorum leaves. They see the plant as an incarnation of the Virgin Mary, and begin the ritual with an invocation to Mary, Saint Peter, the Holy Trinity, and other saints.[16] Ritual use traditionally involves being in a quiet place after ingestion of the leaf—the Maztec shamans say that "La Maria (S. divinorum) speaks with a quiet voice."[23]

It is also used remedially at lower dosages as a diuretic, and to treat ailments including diarrhea, anemia, headaches, rheumatism, and a semi-magical disease known as panzón de borrego, or a swollen belly (literally, "lamb belly").[25][30]

The history of the plant is not well known, and there has been no definitive answer to the question of its origin. Speculation includes Salvia divinorum being a wild plant native to the area; a cultigen of the Mazatecs; or a cultigen introduced by another indigenous group. Botanists have also not been able to determine whether it is a hybrid or a cultigen.[33]

Academic discovery

Salvia divinorum was first recorded in print by Jean Basset Johnson in 1939 while he was studying Mazatec shamanism.[34] He later documented its usage and reported its effects through personal testimonials.[35] It was not until the 1990s that the psychoactive mechanism was identified by a team led by Daniel Siebert.[36]

Gordon Wasson tentatively postulated that the plant could be the mythological pipiltzintzintli, the "Noble Prince" of the Aztec codices.[18][37] Wasson's speculation has been the subject of further debate amongst ethnobotanists, with some scepticism coming from Leander J. Valdés,[38] and counterpoints more supportive of Wasson's theory from Jonathan Ott.[39]

The identity of another mysterious Aztec entheogen, namely that of poyomatli, has also been suggested as being Salvia divinorum.[40] Here too there are other candidate plants, notably Cacahuaxochitl (Quararibea funebris),[41] again suggesting that there is no consensus.

Etymology

The genus name, Salvia, was first used by Pliny for a plant that was likely Salvia officinalis (common sage) and is derived from the Latin salvere.[42][43] The specific epithet, divinorum, was given because of the plant's traditional use in divination and healing.[20] it is often loosely translated as "diviner's sage" or "seer's sage".[19] Albert Hofmann, who collected the first plants with Wasson, objected to the new plant being given the name divinorum:

I was not very happy with the name because Salvia divinorum means "Salvia of the ghosts", whereas Salvia divinatorum, the correct name, means "Salvia of the priests", But it is now in the botanical literature under the name Salvia divinorum.[44]

There are many common names for S. divinorum, most of them relating to the plant's association with the Virgin Mary. The Mazatec believe the plant to be an incarnation of the Virgin Mary, so they take great care in handling the plant. The name "Ska Maria Pastora", often shortened to "Ska Maria" or "Ska Pastora", refers to "the leaf or herb of Mary, the Shepherdess." Other Spanish names include "hojas de Maria", "hojas de la Pastora", "hierba (yerba) Maria", and "la Maria". A plant believed to be S. divinorum was referred to as "hoja de adivinacion" (leaf of prophecy) by the Cuicatec and Mazatec.[16] S. divinorum is also known as la hembra ("the female"), when it is included by the Mazatec as part of a family of similar religious hallucinogens. The others it is connected with are Coleus pumila, called el macho ("the male"), and two forms of Coleus blumei which are called el nene ("the child") and el ahijado ("the godson").[33]

Some researchers see the lack of an indigenous Mazatec name as demonstrating a non-Mazatec origin for the plant. Others point out that the Virgin Mary is not normally viewed as a shepherdess in Christianity, and that image may hint at a pre-Hispanic Mazatec cultural reference to the plant.[33]

Recent history

Salvia divinorum has become both increasingly well-known and available in modern culture. The Internet has allowed for the growth of many businesses selling live salvia plants, dried leaves, extracts, and other preparations.

Medical experts, as well as accident and emergency rooms, have not been reporting cases that suggest particular salvia-related health concerns, and police have not been reporting it as a significant issue with regard to public order offences;[45] in any case, Salvia divinorum has attracted negative attention from the media and some lawmakers.[46]

Media stories generally raise alarms over Salvia divinorum's legal status and are sometimes headlined with generally ill-supported comparisons to LSD or other psychoactive substances. Parental concerns are raised by focusing on salvia's usage by younger teens—the emergence of YouTube videos purporting to depict its use being an area of particular concern in this respect.[citation needed] The isolated and controversial suicide of Brett Chidester received much media attention.

Salvia divinorum was the subject of the first use of YouTube within drug-behavioral research when scientists at San Diego State University rated randomly selected videos of salvia users to study observed impairment.[47][48] Their findings corroborate reports that the most profound effects of smoking salvia appear almost immediately and last about eight minutes. Effects include temporary speech and coordination loss.[49]

Botany

Salvia divinorum has large green ovate (often also dentate) leaves,[50] with a yellow undertone that reach 10 to 30 cm (4 to 12 in) long. The leaves have no hairs on either surface, and little or no petiole.[21] The plant grows to well over 1 metre (3 ft) in height,[16] on hollow square stems which tend to break or trail on the ground, with the plant rooting quite readily at the nodes and internodes.[51]

The flowers, which bloom only rarely, grow in whorls on a 30-centimetre (12 in) inflorescence, with about six flowers to each whorl. The 3-centimetre (1.2 in) flowers are white, curved and covered with hairs, and held in a small violet calyx that is covered in hairs and glands. When it does bloom in its native habitat, it does so from September to May.[51]

Early authors erred in describing the flowers as having blue corollas, based on Epling and Játiva's description. The first plant material they received was dried, so they based the flower color on an erroneous description by Hofmann and Wasson, who didn't realize that their "blue flowers, crowned with a white dome" were in fact violet calyces with unopened white corollas.[16][51][52]

Distribution and habitat

Salvia divinorum is endemic to the Sierra Mazateca in the state of Oaxaca in Mexico, growing in the primary or secondary cloud forest and tropical evergreen forest at elevations from 300 to 1,830 metres (980 to 6,000 ft). Its most common habitat is black soil along stream banks where small trees and bushes provide an environment of low light and high humidity.[51][53]

Reproduction

Salvia divinorum produces few viable seeds even when it does flower—no seeds have ever been observed on plants in the wild. For an unknown reason, pollen fertility is also comparatively reduced. There is no active pollen tube inhibition within the style, but some event or process after the pollen tube reaches the ovary is aberrant. The likeliest explanations are inbreeding depression or hybridity.[23] All of the Mazatec populations appear to be clonal.[54] The plant's square stems break easily and tend to trail on the ground, rooting easily at the nodes and internodes.[55]

Taxonomy

Salvia divinorum was first documented in 1939, but it was many years before botanists could identify the plant due to Mazatec secrecy about the growing sites.[20] Flowers were needed for a definitive identification of the species. In 1962, the Swiss chemist Albert Hofmann, and ethnomycologist R. Gordon Wasson, traveled throughout the Sierra Mazateca researching Mazatec rituals and looking for specimens of the plant. They were unable to locate live plants. Eventually, the Mazatec provided them some flowering specimens.[34] These specimens were sent to botanists Carl Epling and Carlos D. Játiva, who described and named the plant as Salvia divinorum, after its use in divination and healing by the Mazatec.[20] By 1985, up to fifteen populations of the plant had been found.[51]

Until 2010, there were differing opinions on whether Salvia divinorum is an interspecific hybrid. The plant's partial sterility was suggestive of a hybrid origin, though no two parent species have been found with an obvious affinity to Salvia divinorum.[21][22][23] One other possibility for the plant's partial sterility is that long-term cultivation and selection have produced an inbred cultigen.[23][nb 2]

In 2010, a molecular phylogenetic approach by DNA sequencing of Salvia divinorum and a number of related species strongly suggest that the species is not a hybrid.[56] One earlier proposed parent was Salvia cyanea (a synonym for Salvia concolor), which Epling and Játiva believed to be closely allied to Salvia divinorum.[53][57][nb 3] The 2010 study demonstrated Salvia divinorum's closest relative to be Salvia venulosa—a rare and endemic Salvia that is native to Colombia, growing in shaded, wooded gullies at 1,500 to 2,000 m (4,900 to 6,600 ft) elevation. It also showed that Salvia divinorum does not belong to the Salvia section Dusenostachys, as believed earlier. The genetic study also indicated that Salvia venulosa was likely misplaced into Salvia section Tubiflorae, and that it may not be related to other Colombia Salvia species, though further tests are needed.[56]

The origin of Salvia divinorum is still a mystery, one of only three plants in the extensive Salvia genus (approximately 900 species) with unknown origins—the other two are Salvia tingitana and Salvia buchananii.[58]

Strains

Three Salvia divinorum plants

There are two commonly cultivated strains which are known to be distinct. One is the strain that was collected in 1962 by ecologist and psychologist Sterling Bunnell (the Bunnell strain), colloquially mis-attributed as the Wasson-Hofmann strain. The other was collected from Huautla de Jiménez in 1991 by anthropologist Bret Blosser (the Blosser or Palatable strain).[59][60] There are other strains that are not as well documented, such as the Luna strain (possibly Bunnell) isolated from a Hawaiian patch of Salvia divinorum clones, featuring unusually serrated and rounded rather than ovate leaves.[61]

Cultivation

Propagation by cuttings

Salvia divinorum is usually propagated through vegetative reproduction. Small cuttings, between two and eight inches long, cut off of the mother plant just below a node, will usually root in plain tap water within two or three weeks.[62][63]

Flowering

Blooms occur when the day length becomes shorter than 12 hours (beginning in mid-October in some places), necessitating a shade cloth in urban environments with exposure to light pollution (HPS).[64]

Chemistry

For more details on this topic, see Salvinorin A.

Salvinorin A

The known active constituent of Salvia divinorum is a trans-neoclerodane diterpenoid known as salvinorin A (chemical formula C23H28O8).[65] This compound is present in the dried plant at about 0.18%.[39]

Salvinorin A is not an alkaloid, (meaning it does not contain a basic nitrogen), unlike most known opioid receptor ligands.[66] Salvinorin A is the first documented diterpene hallucinogen.[50]

Similar to many psychoactive herbs, Salvia divinorum synthesizes and excretes its active constituent (salvinorin A) via trichomes, of the peltate-glandular morphology, located just beneath the cuticle (subcuticular) layer.[67][68]

Potency

By mass, salvinorin A "is the most potent naturally occurring hallucinogen."[69] It is active at doses as low as 200 µg.[36][65][69] Synthetic chemicals, such as LSD (active at 20–30 µg doses), can be more potent.[70] Research has shown that salvinorin A is a potent and selective κ-Opioid (kappa-Opioid) receptor agonist.[65][71] It has been reported that the effects of salvinorin A in mice are blocked by κ-Opioid receptor antagonists.[26] However, it is an even more potent D2 receptor partial agonist, and it is likely this action plays a significant role in its effects as well.[27] Salvinorin A has no actions at the 5-HT2A serotonin receptor, the principal molecular target responsible for the actions of 'classic' hallucinogens, such as mescaline and LSD, nor is it known to have affinity for any other sites to date.[26]

Salvinorin's potency should not be confused with toxicity. Rodents chronically exposed to dosages many times greater than those to which humans are exposed show no signs of organ damage.[28]

Other terpenoids

Other terpenoids have been isolated from Salvia divinorum, including other salvinorins and related compounds named divinatorins and salvinicins.[72] None of these compounds has shown significant (sub-micromolar) affinity at the κ-Opioid receptor, and there is no evidence that they contribute to the plant's psychoactivity.[73][74]

Other pharmaceutical action

Salvinorin A is capable of inhibiting excess intestinal motility (e.g. diarrhea), through a combination of κ-opioid and cannabinoid (mainly CB1 receptor) receptors in inflamed but not normal gut in vivo. The mechanism of action for Salvinorin A on ileal tissue has been described as 'prejunctional', as it was able to modify electrically induced contractions, but not those of exogenous acetylcholine.[75] Results from a small study by an assistant professor at the University of Iowa indicate that it may have potential as an analgesic and as a therapeutic tool for treating drug addictions.[76][77]

A pharmacologically important aspect of the contraction-reducing (antispasmodic) properties of ingested Salvinorin A on gut tissue is that it is only pharmacologically active on inflamed and not normal tissue, thus reducing possible side-effects.[78]

Ingestion

There are a few ways to consume Salvia divinorum. In traditional Mazatec ritual, shamans use only fresh Salvia divinorum leaves. Modern methods have been developed to more effectively absorb the active principle, salvinorin A. If enough salvinorin A is absorbed, an altered state of consciousness can occur. The duration of experience varies with the method of ingestion and the amount of salvinorin A absorbed.

Traditional methods

Mazatec shamans crush the leaves to extract leaf juices from about 20 to 80 (about 50g/2 oz to 200g/7 oz.) or more fresh leaves. They usually mix these juices with water to create an infusion or 'tea' which they drink to induce visions in ritual healing ceremonies.[30]

Chewing and swallowing a large number of fresh leaves is the other Mazatec method.[79][80] Oral consumption of the leaf makes the effects come on more slowly, over a period of 10 to 20 minutes. The experience, from the onset of effects, lasts from about 30 minutes up to one and a half hours.[81]

Doses for chewing vastly exceed doses used for smoking. By calculating the concentrations per leaf ("an average concentration of 2.45 mg per gram" of leaf),[82] the average weight per leaf ("about 50 g" per 20 leaves, or 2.5g/leaf),[83] and the standard dose for chewing (about 8-28 leaves),[79] the doses can range from about 50 mg to 172 mg.

Modern methods

Modern methods of ingestion include smoking or chewing the leaf, or using a tincture, as described in the following sections.

A pile of brownish-dark green dried leaf pieces, with a ruler for measurement. The pieces are generally round with diameters of 1 to 4 mm. Some pieces are rectangular, about 1 to 3 mm wide and 3 to 8 mm long.
1/2 g. of 25x S. divinorum extract.
Salvia divinorum is becoming more widely known and used in modern culture. The National Survey on Drug Use and Health, an annual US based survey sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA), for 2006 estimated that about 1.8 million persons aged 12 or older had used Salvia divinorum in their lifetime, of which approximately 750,000 had done so in that year.[84] The following year, 2007, saw the annual figure rise from 750,000 to 1 million US users.[85]

Smoking

Dry leaves can be smoked in a pipe, or through the use of a water pipe to cool the smoke.[86] The temperature required to release salvinorin from the plant material is quite high (about 240°C). A cooler flame will work, but the direct application of a more intense flame, such as that of a torch lighter, is often preferred.[86]

Some find that untreated dry leaf produces unnoticeable or only light effects.[79] Concentrated preparations or extracts which may be smoked in place of untreated leaves, have become widely available. This enhanced (or "fortified") leaf is described by a number followed by an x (e.g. 5x, 10x), the multiplicative factors being generally indicative of the relative amounts of leaf concentrate, though there is no accepted standard for these claims. Other sources may use a system of color codes to form their own standards of potency; for example, "green", "yellow", and "red."

These grades of potency may be roughly indicative of the relative concentration of the active principle, (salvinorin A), but the measure should not be taken as absolute. Overall extract potency will depend on the (naturally varying) strength of the untreated leaf used in preparing the extract, as well as the efficiency of the extraction process itself. Extracts reduce the overall amount of inhalations needed to ingest a given amount of active principle, thus facilitating more powerful experiences.[87]

If salvia is smoked, then the main effects are experienced quickly. The most intense 'peak' is reached within a minute or so and lasts for 1–5 minutes, followed by a gradual tapering off. At 5–10 minutes, less intense yet still noticeable effects typically persist, giving way to a returning sense of the everyday and familiar until back to baseline after about 15 to 20 minutes.[81]

Quid chewing

The traditional method of chewing the leaves has continued in modern use. However, salvinorin A is generally considered to be inactive when orally ingested, as salvinorin A is effectively deactivated by the gastrointestinal system.[88] Therefore, in what's understood to be a modern innovation, the 'quid' of leaves is held in the mouth as long as possible in order to facilitate absorption of the active constituents through the oral mucosa.[53] 'Quid' refers to the fact that at the end of this method the user spits out the leaves rather than swallowing them because ingesting the leaves has no known effect. Chewing consumes more of the plant than smoking, and produces a longer-lasting experience.

Using a tincture

Less commonly, some may ingest salvia in the form of a tincture. This is administered sublingually, usually with the aid of a glass dropper. It may be taken diluted with water just before use, which may slightly reduce the intensity of its effects, but can also serve to lessen or avoid a stinging sensation in the mouth caused by the presence of alcohol. Tinctures vary in potency, and the effects can range from inducing a mild meditative state to bringing about a more intense visionary one.[79]

When taken as a tincture the effects and duration are similar to other methods of oral ingestion, though they may be significantly more intense, depending on extract potency.[79]

Immediate effects

Psychedelic experiences are necessarily somewhat subjective and variations in reported effects are to be expected. Aside from individual reported experiences there has been a limited amount of published work summarising the effects. D.M. Turner's book Salvinorin—The Psychedelic Essence of Salvia Divinorum quotes Daniel Siebert's summarisation, mentioning that the effects may include:[89]

  • Uncontrollable laughter
  • Past memories, such as revisiting places from childhood memory
  • Sensations of motion, or being pulled or twisted by forces
  • Visions of membranes, films and various two-dimensional surfaces
  • Merging with or becoming objects
  • Overlapping realities, such as the perception of being in several locations at once

There also may be synesthetic experiences.[90] Glossolalia (speaking in tongues) has been reported by Reason.[85]

A survey of salvia users found that 38% described the effects as unique in comparison to other methods of altering consciousness. 23% said the effects were like yoga, meditation or trance.[91]

One firsthand journalistic account has been published in the UK science magazine New Scientist (note: the dose for this experience was not reported):

The salvia took me on a consciousness-expanding journey unlike any other I have ever experienced. My body felt disconnected from 'me' and objects and people appeared cartoonish, surreal and marvellous. Then, as suddenly as it had began, it was over. The visions vanished and I was back in my bedroom. I spoke to my 'sitter'—the friend who was watching over me, as recommended on the packaging—but my mouth was awkward and clumsy. When I attempted to stand my coordination was off. Within a couple of minutes, however, I was fine and clear-headed, though dripping with sweat. The whole experience had lasted less than 5 minutes.
—Gaia 2006-09-29 (UK Media)

There have been few books published on the subject. One notable example is Dale Pendell's work "Pharmako/Poeia—Plants Powers, Poisons, and Herbcraft", which won the 1996 Firecracker Alternative Book Award[92] and has a chapter dedicated to Salvia divinorum. It includes some experience accounts:

It's very intense, I call it a reality stutter, or a reality strobing. I think that having been a test pilot, and flying in that unforgiving environment with only two feet between our wingtips, helped to prepare me for this kind of exploration.
—Pendell 1995

Other users have written extensive prose and/or poetry about their experiences;[93][94] some describe their visions pictorially, and there exist examples of visionary art which are 'salvia-inspired'. Others claim musical inspiration from the plant: including "Salvia divinorum" by 1200 Micrograms, "Salvia" by Deepwater Sunshine, and "Flight 77" by Paul Dereas.[94]

Cautionary notes

Dale Pendell expresses some concerns about the use of highly concentrated forms of salvia. In its natural form salvia is more balanced and benevolent, and quite strong enough, he argues. High strength extracts on the other hand can show "a more precipitous, and more terrifying, face" and many who try it this way may never wish to repeat the experience.[95]

The Salvia Divinorum User's Guide recommends having a trip sitter present to those who are new to salvia, are experimenting with a stronger form, or are using a more effective method of ingestion.

The guide says that while the effects of salvia are generally quite different from those of alcohol, like alcohol, it impairs coordination. It also emphasizes that salvia is not a 'party drug.'

Salvia is not 'fun' in the way that alcohol or cannabis can be. If you try to party with salvia you probably will not have a good experience. Salvia is a consciousness-changing herb that can be used in a vision quest, or in a healing ritual. In the right setting, salvia makes it possible to see visions. It is an herb with a long tradition of sacred use. It is useful for deep meditation. It is best taken in a quiet, nearly dark room; either alone, or with one or two good friends present.
—Salvia divinorum User's Guide

Vaporization

Daniel Siebert cautions that inhaling hot air can be irritating and potentially damaging to the lungs. Vapor produced by a heat gun needs to be cooled by running it through a water pipe or cooling chamber before inhalation.[96]

The vaporizers that have been reported effective for use with dried S. divinorum leaves are those that use a paint stripper “heat gun” as the heat source. These get very hot, and people have reported that they work quite well sometimes too well—for smoking dried S. divinorum leaves; we have heard of several people using this type of vaporizer who had experiences that were too intense, including one report of someone passing out. Measuring an accurate dose with these devices can be quite tricky, and they are not recommended.
—Salvia Divinorum and Salvinorin A, Second Edition, p41
An experienced salvia user who is chewing a quid, may often choose to do it alone, and may be quite safe in doing so. But having a pleasant, sensible, sober sitter is an absolute must if you are trying vaporization, smoking high doses of extract-enhanced leaves, or using pure salvinorin.

After-effects

Short term

After the peak effects, normal awareness-of-self and the immediate surroundings return but lingering effects may be felt. These short-term lingering effects have a completely different character than the peak experience. About half of users report a pleasing 'afterglow', or pleasant state of mind following the main effects. Researchers from the University of California and California Pacific Medical Center Research Institute conducted a survey of 500 salvia users which identified that they 'sometimes or often' experience certain effects, including:[97]

Increased insight: 47% Decreased insight: 1.8%
Improved mood: 44.8% Worsened mood: 4.0%
Increased connection with Universe or Nature: 39.8%    Decreased connection with Universe or Nature: 5.4%
Increased sweating: 28.2% Decreased sweating: 1.6%
Body felt warm or hot: 25.2% Body felt cold: 6.4%
Increased self-confidence: 21.6% Decreased self-confidence: 2.4%
Improved concentration: 19.4% Difficulty concentrating: 12.0%

Other commonly reported effects include:

  • Feelings of calmness: 42.2%
  • Weird thoughts: 36.4%
  • Things seeming unreal: 32.4%
  • Floating feelings: 32%
  • Mind racing: 23.2%
  • Feeling lightheaded: 22.2%

Long term

Differing studies suggest no consensus so far with regard to the long-term effects of Salvia divinorum on mood. It is well-established that some k-opioid agonists can cause dysphoria in humans.[98] One study using rats in forced-swim tests has been used to suggest that Salvia divinorum may have "depressive-like" effects,[99] although this conclusion has been contradicted by subsequent research.[100] However, a report has been published detailing an individual case of Salvia divinorum use as self-medicated treatment for depression,[101] and Baggott's survey of 500 people with firsthand experience of salvia found that 25.8% of respondents reported improved mood and "antidepressant-like effects" lasting 24 hours or longer. Only 4.4% reported persisting (24 hours or more) negative effects (most often anxiety) on at least one occasion.[91]

There has been one report of salvia precipitating psychosis. However, the authors suspected that their patient was already genetically predisposed to schizophrenia.[102]

It has been suggested that the long-term effects of salvia use may include feelings of déjà vu.[103]

The Baggott survey found little evidence of addictive potential (chemical dependence) in its survey population. 0.6% percent of respondents reported feeling addicted to or dependent on salvia at some point, and 1.2% reported strong cravings. About this the researchers said "there were too few of these individuals to interpret their reports with any confidence".

Most users report no hangover or negative after-effects (e.g. withdrawal, comedown or rebound effect) the next day. This is consistent with the apparent low toxicity of salvia indicated by research conducted at the University of Nebraska.[28]

Therapeutic potential

Aside from individual reports of self-medicated use in the treatment of depression,[101][104] research suggests that Salvia divinorum, in line with the studied effects of other κ-opioid agonists,[105] may have further therapeutic potential.

Thomas Prisinzano, assistant professor of medicinal and natural products chemistry at the University of Iowa, has suggested that salvia may help treat cocaine addiction:

You can give a rat free access to cocaine, give them free access to Salvinorin A, and they stop taking cocaine.
—Masis 2007-02-28 (US Media)

Professor Bryan L. Roth, director of the National Institute on Mental Health's Psychoactive Drug Screening Program, has said:

We think that drugs derived from the active ingredient could be useful for a range of diseases: Alzheimer's, depression, schizophrenia, chronic pain and even AIDS or HIV.
—Viren 2007-08-23 (US Media)

Clinical pharmacologist John Mendelsohn has also said:

There may be some derivatives that could be made that would actually be active against cancer and HIV [...] At the present time, there are a lot of therapeutic targets that have many people excited.

An ABC news story which reported on this went on to suggest "the excitement could vanish overnight if the federal government criminalized the sale or possession of salvia, as the Drug Enforcement Agency is considering doing right now."[104] A proposed Schedule I classification would mean (among other things) that there's no "currently accepted medical use" as far as the United States government is concerned.[106] Scientists worry that such legislation would restrict further work.[107][108] Mendelsohn said scheduling salvia could scare away a great deal of research and development into salvia's therapeutic promise.[104]

Controversy

A rectangular plastic re-sealable zipper storage bag that appears to be approximately 10 by 15 centimeters. The bag has a white label and a large wavy orange stripe. The top of the label reads: "THE STANDARDIZED SALVIA DIVINORUM" in large letters and "STANDARDIZED 20X EXTRACT" in smaller letters immediately below. The bottom of the label reads "8 mg STANDARDIZED SALVINORIN-A EXTRACT" in small letters. Affixed to the bag is an orange price tag reading "SPECIAL $5.99."
Salvia extract as it is commonly sold in stores where it is legal.

The relatively recent emergence of Salvia divinorum in modern Western culture, in comparison to its long continuing traditions of indigenous use, contrasts widely differing attitudes on the subject.

Opinions range from veneration of the plant as a spiritual sacrament or "a gift from the gods",[30][109] to 'threat to society', to be banned as quickly as possible in order to "spare countless families the horror of losing a loved one to the relentless tentacles of drug abuse".[110]

Interest in Salvia divinorum has been escalating in the news media, particularly in the United States, where an increasing number of newspaper reports have been published and television news stories broadcast.[111]

These stories generally raise alarms over salvia's legal status. Headlining for example with comparisons to LSD,[112][113][114] or describing it as "the new pot"[115] for instance, with parental concerns being raised by particular focus on salvia's use by younger teens.

Story headlines may also include 'danger' keywords, such as "Dangerous Herb is Legal..."[116] or "Deadly Dangers Of A Street Legal High".[117]

Mainstream news coverage and journalistic opinion has widely been negative on the subject. In a local news report aired on ABC affiliate WJLA in Washington, DC on July 11, 2007, the anchors are seen to exchange expressions of incredulity when referring to a salvia story with the following introduction "Now, an exclusive I-Team investigation of a hallucinogenic drug that has begun to sweep the nation. What might amaze you is that right now the federal government is doing nothing to stop it".[118]

In March 2008 a Texas news report aired with the story "A legal drug that teenagers are now using to get high could soon be banned here in San Antonio - all because of a Fox News 4 investigation", going on to say, "The drug is legal in Texas, at least for now. But a News 4 investigation could lead to a new ordinance to protect your kids."[119]

Many salvia media stories headline with comparisons to LSD. However, while LSD and salvia's active constituent salvinorin A may have comparative potencies, in the sense that both can produce their effects with low dosage amounts, they are otherwise quite different. The two substances are not chemically similar or related, as salvinorin A is found naturally in a single plant while LSD is chemically semisynthesized from lysergamides like ergotamine. They are ingested in different ways and produce different effects, which manifest themselves over different timescales. For example, the effects of salvia when smoked typically last for only a few minutes as compared to LSD, whose effects can persist for 8–12 hours.[81][120]

Brett's law

Main article: Brett's law

A particular focus of many US media stories is the long-running coverage of the case of Brett Chidester,[118][121] a 17-year-old Delaware student who committed suicide in January 2006 by carbon monoxide poisoning.

Reportedly, some months before this, Brett's mother Kathleen Chidester had learned about his salvia use and questioned him about it. Brett said that he had ceased his experimentation, but his parents did not believe that he was telling the truth. They have instead argued that salvia-induced depression was largely to blame for his death. Some of Brett's earlier writings about his salvia experiences have been used to suggest that it made him think "existence in general is pointless." Some media stories have referred to these earlier written experience reports as if they were part of Brett's suicide note.[108][121] In any case, a law was soon passed in Delaware classifying the herb as a Schedule I controlled substance in that state. This legislation was nicknamed Brett's law (formally referred to as Senate bill 259).[122]

Although the Chidester story has been given continued exposure by US media, there has not been anywhere else, either before or since this controversial incident, any other reported cases involving or alleging Salvia divinorum as a serious factor in suicide, overdose, accidental, or any other kind of death. Regarding this, San Francisco attorney Alex Coolman has commented, "It's remarkable that Chidester's parents, and only Chidester's parents, continue to be cited over and over again by the mainstream media in their coverage of the supposed 'controversy' over the risks of Salvia divinorum."[123]

Kathleen Chidester has continued campaigning for "Schedule I"-like legislation beyond their home state of Delaware. For example, three years after Brett's death, in written testimony in support of Senator Richard Colburn's proposed Senate Bill to the Maryland State Legislature, saying, "My hope and goal is to have salvia regulated across the US. It's my son's legacy and I will not end my fight until this happens."[124]

Usage shown on YouTube

A reported concern has been the emergence of YouTube videos showing alleged salvia users laughing uncontrollably, apparently unable to perform simple tasks or to communicate.[118][125] In an interview with California-based newspaper the San Francisco Chronicle, published in June 2007, Daniel Siebert was quoted as saying:

"Those videos are certainly not going to help the situation. They make salvia look like some horrible drug that makes people nuts and dangerous [...]" and "The sad thing is it creates this public image where people don't realize there are sensible ways to use something like this."[126]

The New York Times has reported that "in state after state [...] the YouTube videos have become Exhibit A in legislative efforts to regulate salvia."

Waco Representative Charles Anderson (R), who is sponsoring one of several bills to ban salvia in Texas saying, "When you see it, well, it sure makes a believer out of you." Anderson told colleagues at a legislative hearing about a video that depicts a salvia user behind the wheel of a car.[nb 4]

"What we really worry about," said Mr. Anderson at the hearing, "is youngsters doing this and then getting in a vehicle or getting on a motorcycle or jumping in a pool somewhere."[5]

Michigan Representative Michael Sak (D) submitted a bill which proposed Schedule I classification of Salvia divinorum and salvinorin A.[127] He said that if people had questions about the deleterious effects of salvia, they should go on YouTube to watch the videos. A reporter questioned Sak as to whether he had ever seen a "Girls Gone Wild" video, and whether that would incite him to make alcohol illegal (Sak replied that he hadn't yet had a chance to review the material).[nb 5]

Nebraska Senator Vickie McDonald said:

"Anytime anything's on YouTube it's an issue," and "Legislators, parents, grandparents, we need to be on top of these things," [...] "We need to protect our children..."[128][129]

Senator McDonald of Nebraska proposed Schedule I listing Salvia divinorum as part of their Controlled Substances Act, under which possession of salvia would have been considered a Class IV felony with a penalty of up to five years and trafficking would have fallen under a Class III felony with up to a 20 year penalty.[129]

In Massachusetts, YouTube videos were shown by a retired police officer to public health and judiciary committees as evidence in favor of outlawing it there.[130]

The issue has been raised of whether the salvia videos are in breach of YouTube's own community guidelines, which ask users not to "cross the line" and post videos showing "bad stuff" like "drug abuse".[131] The question is considered as particularly problematical as the videos may be something of an enforcement grey area.[132]

Legal status

Main article: Legal status of Salvia divinorum

At present Salvia divinorum remains legal in most countries. Countries where salvia is controlled in some manner include: Australia, Belgium, Canada, Denmark, Estonia, Finland, Italy, Japan, the United States, Russia, Spain, and Sweden.[32][133][134]

The prohibitive degree of Salvia divinorum legislation varies widely from country to country. Australia has imposed its strictest 'schedule 9' (US Schedule I equivalent), and Italy has also placed salvia in its 'Table I' of controlled substances (also US Schedule I equivalent). In Spain, there are controls focusing only on the commercial trade of Salvia divinorum, personal cultivation (i.e. for non-commercial use) is not targeted.[133][134]

Salvia legislation may prove difficult to enforce. The plant has a nondescript appearance; unlike many other drug plants, the leaves are non-descript, and without a detectable odour. Salvia divinorum can be grown as an ordinary houseplant without the need of special equipment such as hydroponics or high-power lights.[135][136][nb 1]

UK legality

In the United Kingdom, following a local newspaper story in October 2005,[137] a parliamentary Early Day Motion was raised calling for Salvia divinorum to be banned there. However, it only received 11 signatures.[138] A second motion raised in October 2008 attracted 18 signatures,[139] and it was reported that Mann had also written to Jacqui Smith, then Home Secretary. The Advisory Council on the Misuse of Drugs, the independent body that advises UK government on drugs, was asked to investigate further.[140]

US legality

Main article: Legal status of Salvia divinorum in the United States

National legislation for amendment of the Controlled Substances Act to place salvinorin A and Salvia divinorum in Schedule I at the federal level in the United States was proposed in 2002 by Representative Joe Baca (D- California). Those opposed to bill HR 5607 include Daniel Siebert, who sent a letter to Congress arguing against the proposed legislation,[141] and the Center for Cognitive Liberty and Ethics (CCLE), who sent key members of the US Congress a report on Salvia divinorum and its active principle,[19] along with letters from an array of scientists who expressed concern that scheduling Salvia divinorum would negatively impact important research on the plant. The bill did not pass.[142][143][144]

Although salvia is not regulated under the Controlled Substances Act, some American states, including Alabama, Delaware, Illinois, Louisiana, Michigan, Missouri, Ohio, Texas and others, have passed their own laws.[32][145][146] Several other states have proposed legislation against salvia, including Alaska, California, Florida, Iowa, Maryland, New Jersey, New York, Oregon, and Pennsylvania. Many of these proposals have not made it into law, with motions having failed, stalled or otherwise died, for example at committee review stages.[133][134]

Where individual state legislation does exist, it varies from state to state in its prohibitive degree.[133]

Salvia divinorum has been banned by various branches of the U.S. military and some military bases.[147][148][149][150]

Internet sale

Some internet vendors will not sell live salvia cuttings, leaf, or leaf products to states where its use is restricted or prohibited.[151]

Per their drugs and drug paraphernelia policy, eBay does not permit sale of Salvia divinorum or derived products (despite legality in most areas).[152]

Opinions and arguments

Concerns expressed by some politicians on the subject of Salvia reflect those of the media, with comparisons to LSD and particular focus on "protecting our children" being echoed;[112][153][154] and with legislative proposals following soon after news stories breaking.[116][119][14][155][156]

Some arguments against Salvia have been of a preventative nature, "We need to stop this before it gets to be a huge problem not after it gets to be a huge problem,"[157] or of an imitative nature, "The Australians have clearly found a problem with it. There's obviously a risk in people taking it."[137] Concerns about driving while under the influence of Salvia have also been expressed.[158][159]

Opponents of more prohibitive measures against Salvia argue that such reactions are largely due to an inherent prejudice and a particular cultural bias rather than any actual balance of evidence, pointing out inconsistencies in attitudes toward other more toxic and addictive drugs such as alcohol and nicotine.[160][nb 6][nb 7] While not objecting to some form of legal control, in particular with regard to the sale to minors or sale of enhanced high-strength extracts, most salvia proponents otherwise argue against stricter legislation.[133]

Those advocating consideration of Salvia divinorum's potential for beneficial use in a modern context argue that more could be learned from Mazatec culture, where salvia is not really associated with notions of drug taking at all and it is rather considered as a spiritual sacrament. In light of this it is argued that Salvia divinorum could be better understood more positively as an entheogen rather than pejoratively as a hallucinogen.[161][nb 8]

Public opinion

Despite its growing notoriety in some circles, media stories generally suggest that the public at large are still mostly unaware of salvia, with the majority perhaps having never even heard of it.[121]

Although published responses may not necessarily be representative of public opinion as a whole, some news agencies generally support reader and viewer feedback in connection with their stories.[110][112][119][121][162]

Notes

  1. ↑ 1.0 1.1 The case of North Dakota resident Kenneth Rau is reported as likely being the first person charged for Salvia divinorum possession in the United States.[1][2] A Nebraska store owner was also charged for selling salvia, but not under the auspices of any specific law against Salvia divinorum. Christian Firoz was instead charged under a general Nebraskan statute where it is illegal to sell a product to induce an intoxicated condition. The jury in the Firoz case returned a verdict of not guilty.[3] The Rau case did not go to jury trail. Rau pleaded guilty to the charge of Class C felony possession of salvia, and also Class A misdemeanor possession of drug paraphernalia and Class B misdemeanor possession of marijuana. He received a deferred imposition of sentence. He will not go to prison, but will be on supervised probation for three years; the charges will be removed from his record if he successfully completes his time on supervision. The judge ordered Rau to complete a chemical dependency evaluation and any recommended treatment and pay $575 in court fees.[4] - See also the North Dakota detail under the main article on the Legal status of Salvia divinorum (and, re the Christian Firoz case, the Nebraska detail).
  2. ↑ Botanist Valdés (1987), wrote that, "It is doubtful that the Salvia is a true cultigen", based partly on his belief that it was first "collected in the highlands and planted in more accessible places, where it becomes naturalized". The main cultigen proponent is Gordon Wasson, who is not a botanist.
  3. ↑ Reisfield is unsure why Epling "used the invalid name (the synonym rather than the valid name S. concolor), nor why he considered this species close to S. divinorum".
  4. ↑ In fact the video is one in a series of parodies featuring Erik J. Hoffstad, a production assistant in Los Angeles. In the film Hoffstad smokes salvia in a parked car (his friends reportedly making sure he did not have the real keys).[5]
  5. ↑ The reporter noted that Sak had received more money from the Michigan Beer and Wine Wholesalers Association than anyone else in the House.[6] According to the National Institute on Money in State Politics, the Michigan Beer and Wine Wholesalers Association was the highest contributor to Zak's 2006 political campaign.[7]
  6. ↑ According to the National Institute on Money in State Politics, which indicates the major sources of campaign contributions for U.S. politicians, a large part of contributions to U.S. Congressional campaigns comes from alcohol and tobacco industries.[13] For example, Oregon Representative John Lim"s third largest individual campaign sponsor in 2006 was the Oregon Beer & Wine Distributors Association[7] Lim(R) argued for Schedule I classification of Salvia in Oregon. Former Delaware Senator Karen Peterson's second largest group campaign donations in 2006 came from "Beer, Wine & Liquor" industries.[7] Peterson(D) introduced Schedule I classification of Salvia divinorum in Delaware. Senator Tim Burchett(R) sponsored Salvia legislation in Tennessee. In 2006, his second largest individual campaign donation came from the Tennessee Malt Beverage Association.[7] In the same period alcohol and tobacco related contributions amounted to the fourth largest industry contributions for Utah Representative Paul Ray(R).[7] Representative Ray submitted a bill calling for Schedule I classification of Salvia in that state.[14] Alcohol related contributions also featured highly for Illinois Representative Dennis Reboletti(R) "Beer, Wine & Liquor" was his ninth highest industry contributor in 2006 and 2008.[7] Representative Reboletti sponsored a bill for Schedule I classification of Salvia divinorum in Illinois.[15]
  7. ↑ The worldwide number of alcohol-related deaths is calculated at over 2,000 people per day,[11] in the US the number is over 300 deaths per day.[12]
  8. ↑ Other entheogenic plants with continuing traditions principally of spiritual use include peyote (and other psychoactive cacti), iboga, virola, ayahuasca, and various types of psychoactive fungi.[8] Current U.S. Federal Law allows two of these to be used in a spiritual context. The Native American Church is permitted use of peyote; the Uniao do Vegetal (or UDV) is permitted use of ayahuasca.[9] Although not consistently granted (varying from state to state), the principal grounds for such concessions are constitutional,[10] with further grounds following from the Religious Freedom Restoration Act.
