Medical cannabis

From Wikipedia, the free encyclopedia

Cannabis Indica, Fluid Extract, American Druggists Syndicate, pre-1937

Medical cannabis refers to the use of the drug cannabis as a physician-recommended herbal therapy, most notably as an antiemetic (to treat vomiting and nausea). So far, the medical use of cannabis is legal only in a limited number of territories, including Canada, Belgium, Australia, the Netherlands, the United Kingdom, New Zealand, Spain, and U.S. states of California, Alaska, Hawaii, Maine, Nevada, Oregon and Washington. This usage generally requires a prescription, and distribution is usually done within a framework defined by local laws.

There are many studies regarding the use of cannabis in a medicinal context.^[1][2][3][4]

[edit] History

Cannabis sativa from Vienna Dioscurides, 512 A.D.

The use of cannabis, at least as fiber, has been shown to go back at least 10,000 years in Taiwan. Dà má (Pinyin pronunciation) is the Chinese expression for medicinal cannabis, the first character meaning "big" and the the second character meaning "hemp," a pictograph of 2 cannabis plants inside of a house or sheltered area.

Cannabis plant

Cannabis, called dà má (大麻) in Chinese, is known to have been used in Taiwan for fiber starting about 10,000 years ago.^[5] Cannabis has been used for medicinal purposes for approximately 4,000 years.^[6] The Ebers Papyrus from Ancient Egypt (1,550 B.C.) describes medical marihuana.^[7] Surviving texts from ancient India confirm that cannabis' psychoactive properties were recognized, and doctors used it for a variety of illnesses and ailments. These included insomnia, headaches, a whole host of gastrointestinal disorders, and pain: cannabis was frequently used to relieve the pain of childbirth. The ancient Egyptians even used hemp (cannabis) in suppositories for relieving the pain of hemorrhoids.^[8] The egyptologist Lise Manniche notes the reference to "plant medical marijuana" in several Egyptian texts, one of which dates back to the eighteenth century B.C.^[9] Cannabis is also mentioned in The Divine Farmer's Herb-Root Classic, an ancient Chinese pharmacopoeia attributed to Emperor Shennong.^{[citation needed]} Cannabis was prescribed to treat vomiting, infectious and parasitic hemorrhaging.

In the medieval Islamic world, Arabic physicians discovered the diuretic, antiemetic, antiepileptic, anti-inflammatory, pain killing and antipyretic properties of cannabis sativa, and used it extensively as medication from the 8th to 18th centuries.^[10] An Irish doctor, William O'Shaughnessy, was held mainly responsible for showing his Western colleagues about the healing properties of marijuana. He was a herb professor at the Medical College of Calcutta, and in conducted a marijuana experiment in the 1830s. O'Shaughnessy created preparations and tested animal effects. He continued on to administer this marijuana to patients in order to help treat muscle spasms or pain.^[11]

An advertisement for cannabis americana distributed by a pharmacist in New York in 1917.

Cannabis as a medicine became common throughout much of the world by the 19th century. It was used as the primary pain reliever until the invention of aspirin.^[6] Modern medical and scientific inquiry began with doctors like O'Shaughnessy and Moreau de Tours, who used it to treat melancholia and migraines, and as a sleeping aid, analgesic and anticonvulsant.

By the time the United States banned cannabis in a federal law, the 1937 Marijuana Tax Act, the plant was no longer extremely popular.^{[citation needed]} Skepticism about marijuana arose in response to the bill.^{[citation needed]}

Later in the century, researchers investigating methods of detecting cannabis intoxication discovered that smoking the drug reduced intraocular pressure.^[12]

In 1972 Tod H. Mikuriya, M.D. reignited the debate concerning marijuana as medicine when he published "Marijuana Medical Papers 1839-1972."High intraocular pressure causes blindness in glaucoma patients, so many believed that using the drug could prevent blindness in patients. Many Vietnam War veterans also believed that the drug prevented muscle spasms caused by battle-induced spinal injuries. Later medical use has focused primarily on its role in preventing the wasting syndromes and chronic loss of appetite associated with chemotherapy and AIDS, along with a variety of rare muscular and skeletal disorders. Less commonly, cannabis has been used in the treatment of alcoholism and addiction to other drugs such as heroin and the prevention of migraines. In recent years, studies have shown or researchers have speculated that the main chemical in the drug, THC, might help prevent atherosclerosis.

Later, in the 1970s, a synthetic version of THC, the primary active ingredient in cannabis, was synthesized to make the drug Marinol. Users reported several problems with Marinol, however, that led many to abandon the pill and resume smoking the plant. Patients complained that the violent nausea associated with chemotherapy made swallowing pills difficult. The effects of smoked cannabis are felt almost immediately, and is therefore easily dosed.^[13] Marinol (Jojel), like ingested cannabis, is very psychoactive, and is harder to titrate than smoked cannabis.^[14] Marinol has also consistently been more expensive than herbal cannabis.^[15] Some studies have indicated that other chemicals in the plant may have a synergistic effect with THC.^[16]

In addition, during the 1970s and 1980s, six U.S. states' health departments performed studies on the use of medical marijuana. These are widely considered some of the most useful and pioneering studies on the subject.^{[citation needed]} Voters in the following eight states showed their support for marijuana prescriptions given by physicians between 1996 and 1999: "Alaska, Arizona, California, Colorado, Maine, Nevada, Oregon, and Washington", going against policies of the federal government.^[17]

In May 2001, "The Chronic Cannabis Use in the Compassionate Investigational New Drug Program: An Examination of Benefits and Adverse Effects of Legal Clinical Cannabis" (Russo, Mathre, Byrne et al) was completed. This three-day examination of major body functions of four of the five living US federal cannabis patients found "mild pulmonary changes" in two patients.^[18]

[edit] Indications

Cannabis is most importantly indicated as an antiemetic for the treatment of nausea and anorexia associated with treatments for cancer, AIDS, and hepatitis. Cannabis also acts as an antispasmodic and anticonvulsant and is indicated for neurological conditions such as epilepsy especially complex partial seizures, multiple sclerosis, and spasms. As an analgesic and an immunomodulator it is indicated for conditions such as migraine, arthritis, spinal and skeletal disorders. As a bronchodilator it is beneficial for asthma. It also reduces the intraocular pressure and is indicated for glaucoma. Recent studies have shown the drug to be efficacious in treating mood disorders and mental health issues such as depression, post traumatic stress disorder, clinical depression, obsessive-compulsive disorder, panic disorder, and bipolar disorder.[3] It is also indicated for premenstrual syndrome, hypertension, and insomnia. It is also reported to be an effective treatment for constipation.

According to a survey on the recommendation of cannabis in California,^[19] cannabis is indicated for over 250 conditions.

[edit] Emerging medical consensus

Dozens of medical organizations have endorsed allowing patients access to medical marijuana with their physicians' approval. These include, but are not limited to, the following:

• The American College of Physicians - America's second largest physicians group^[20]
• Leukemia & Lymphoma Society - America's second largest cancer charity.^[20]
• American Academy of Family Physicians^[20]
• American Public Health Association^[20]
• American Psychiatric Association^[20]
• American Nurses Association^[20]
• British Medical Association^[20]
• AIDS Action^[20]
• American Academy of HIV Medicine^[20]
• Lymphoma Foundation of America^[20]
• Health Canada^[20]

[edit] Pharmacologic THC and THC derivatives

Canadian case of Sativex vials; the world's first artificial pharmaceutical prescription medicine derived from cannabis. Used as a mouth spray, it was first approved in Canada as adjunctive treatment for the symptomatic relief of neuropathic pain in multiple sclerosis and other conditions.

In the USA, the FDA has approved two cannabinoids for use as medical therapies: dronabinol (Marinol) and nabilone. It is important to note that these medicines are not smoked. Dronabinol is a synthetic THC medication,^[21] while nabilone is a synthetic cannabinoid marketed under the brand name Cesamet.

These medications are usually used when first line treatments for nausea fail to work. In extremely high doses and in rare cases there is a possibility of "psychotomimetic" side effects. The other commonly-used antiemetic drugs are not associated with these side effects.

The prescription drug Sativex, an extract of cannabis administered as a sublingual spray, has been approved in Canada for the treatment of multiple sclerosis;^[24] this medication may now be legally imported into the United Kingdom and Spain on prescription.^[25] Dr. William Notcutt is one of the chief researchers that has developed Sativex, he has been working with GW and founder Geoffrey Guy since the company's inception in 1998. Notcutt states that the use of MS as the disease to study "had everything to do with politics."^[26]

[edit] Criticism

See also: Health issues and the effects of cannabis

On 20 April 2006, The United States Food and Drug Administration (FDA) issued an advisory against medical marijuana stating that, "marijuana has a high potential for abuse, has no currently accepted medical use in treatment in the United States, and has a lack of accepted safety for use under medical supervision. Furthermore, there is currently sound evidence that smoked marijuana is harmful." [4]. Some prominent American societies have been reluctant to endorse medicinal cannabis. For example: [5], the National Multiple Sclerosis Society [6] , the American Academy of Ophthalmology [7] and the American Cancer Society [8]. (Federal Register, 1992).

On June 6, 2005, the U.S. Supreme Court handed down a decision which approved the Federal Government's position that federal law permits the prosecution of persons possessing cannabis regardless of the defense that they are medicinal cannabis patients, even in states that exempt its prohibition for medicinal purposes. [9]

The Institute of Medicine, run by the United States National Academy of Sciences, conducted a comprehensive study in 1999 to assess the potential health benefits of cannabis and its constituent cannabinoids. The study concluded that smoking cannabis is not recommended for the treatment of any disease condition, but did conclude that nausea, appetite loss, pain and anxiety can all be mitigated by marijuana. While the study expressed reservations about smoked marijuana due to the health risks associated with smoking, the study team concluded that until another mode of ingestion was perfected that could provide the same relief as smoked marijuana, there was no alternative. In addition, the study pointed out the inherent difficulty in marketing a non patentable herb. Pharmaceutical companies will not substantially profit unless there is a patent. For those reasons, the Institute of Medicine concluded that there is little future in smoked cannabis as a medically approved medication. The report also concluded for certain patients, such as the terminally ill or those with debilitating symptoms, the long-term risks are not of great concern.^[27]

In an unpublished 2001 study by the Mayo Clinic, Marinol was shown to be less effective than megestrol acetate in helping cancer patients regain lost appetites.^[28]

In 2003, the American Academy of Ophthalmology released a position statement asserting that "no scientific evidence has been found that demonstrates increased benefits and/or diminished risks of marijuana use to treat glaucoma compared with the wide variety of pharmaceutical agents now available."^[29]

Since marijuana is illegal in the United States, this policy has led to penalties for simple use and possession. Despite these penalties, users continue to find themselves in trouble with the law and that is why the enforcement of marijuana laws has come to be so ineffective and wasteful. The Connecticut Law Revision Commission made the following evaluation: " (1) the costs of arresting and prosecuting marijuana offenders were significantly lower in states that had done away with criminal penalties for possessing small amounts; (2) there was a greater increase in marijuana use in states that continue to treat possession as crime than in states that treated it as a civil offense; (3) easing the penalties for marijuana did not lead to a substantial increase in the use of either alcohol or hard drugs."^[30]

[edit] Harm reduction

Many medical cannabis opponents note that smoked cannabis is harmful to the respiratory system. However, this harm can be minimalized or eliminated by the use of a vaporizer or ingesting the drug in an edible form or other non-smoking modes of delivery like tinctures. Vaporizers are devices that vaporize the active constituents (cannabinoids) and the fragrant aromatic substances in the preparation without combusting the plant material and thus preventing the formation of toxic substances. Studies have shown that vaporizers can dramatically reduce^[31] or even eliminate^[32] the release of irritants and toxic compounds.

Aspergillus fumigatus

In order to kill microorganisms, especially mold, in cannabis designated for medical use, the scientists "Levitz and Diamond (1991) suggested baking marijuana in home ovens at 150 °C [302 °F], for five minutes before smoking. Oven treatment killed conidia of A. fumigatus, A. flavus and A. niger, and did not degrade the active component of marijuana, tetrahydrocannabinol (THC)."^[33]

[edit] Availability

[edit] Canada

In Canada, the regulation on access to marijuana for medical purposes, established by Health Canada in July 2001, defines two categories of patients eligible for access to medical cannabis. The category 1 list individuals suffering from "acute pain", "violent nausea and/or other serious symptoms caused by the following conditions: multiple sclerosis, spinal cord injury, disease of the spinal cord, cancer, AIDS/HIV infection, severe forms of arthritis and/or epilepsy. The category 2 "key applicants who have serious pathological symptoms other than those described in category 1."^[34] The application of eligible patients must be supported by a doctor.

The cannabis distributed by Health Canada is provided under the brand CanniMed by the company Prairie Plant Systems Inc. That the demand from Canadian authorities would have increased by 80% in 2006 (the output reaching 420 kg the previous year).^[35] However, it is legal for patients approved by Health Canada to grow their own cannabis for personal consumption, and it is possible to obtain a production license as a person designated by a patient. Health Canada noted however that "no notice of compliance has been issued for marijuana for medical purposes."

[edit] Spain

In Spain, since late 1990 and early 2000, medical cannabis underwent a process of progressive decriminalization and legalization. The parliament of the region of Catalonia is the first in Spain have voted unanimously in 2001 legalizing medical marijuana, it is quickly followed by parliaments of Aragon and the Balearic Islands. The Spanish Penal Code prohibits the sale of cannabis but it does not prohibit consumption. Until early 2000, the Penal Code did not distinguish between cannabis and cannabis therapeutic recreation, however, several court decisions show that this distinction is increasingly taken into account by the judges. From 2006, the sale of seed is legalized, possession or consumption is still forbidden in public places but permitted in private premises. Moreover, the cultivation of cannabis plans is now authorized in a private place.

Several studies have been conducted to study the effects of cannabis on patients suffering from disease like cancer, AIDS, multiple sclerosis, the seizures or the asthma. This research was conducted by various Spanish agencies at the Universidad Complutense de Madrid headed by Dr. Manuel Guzman, the hospital of La Laguna in Tenerife led neurosurgeon Luis González Feria or the University of Barcelona.

After legislation, several cannabis clubs have been established including the Basque Country and Catalonia. These clubs, the first of its kind in Europe, are non-profit associations who grow cannabis and sell it at cost to its members. In 2006, members of these clubs were acquitted in trial for possession and sale of cannabis.

[edit] United States

Map of U.S. state cannabis laws (2007)
     State with legal medical cannabis.      State with decriminalized cannabis possession laws.      State with both medical and decriminalization laws.

In the United States, the Federal Food, Drug, and Cosmetic Act makes the Food and Drug Administration (FDA) the sole government entity responsible for ensuring the safety and efficacy of new prescription and over-the-counter drugs, overseeing the labeling and marketing of drugs, and regulating the manufacturing and packaging of drugs.^[36] The FDA defines a drug as safe and effective for a specific indication if the clinical benefits to the patient are felt to outweigh any health risks the drug might pose. FDA and comparable authorities in Western Europe including the Netherlands, have not approved smoked marijuana for any condition or disease.^[37][38] Cannabis remains illegal throughout the United States and is not approved for prescription as medicine, although 12 states - Alaska, California, Colorado, Hawaii, Maine, Montana, Nevada, New Mexico, Oregon, Rhode Island, Vermont and Washington - approve and regulate its medical use. (The federal government continues to enforce its prohibition in these states.) However, there are also 2 states, Arizona and Maryland, whose drug laws are favourable towards the medicinal use of marijuana, in the later case making it a non-incarcerable offense with a maximum penalty of a $100 fine, [10] but which still explicitly ban it.

Potential health benefits aside, marijuana remains a US Federally controlled substance, making possession and distribution illegal. It has been estimated that an average marijuana clinic consumes a pound of cannabis per day,^{[citation needed]} making acquisition a critical challenge. This acquisition may have to resort to more traditionally crime-associated, black-market sources, contributing to crime in communities. This point was illustrated in early 2007, with the murder of Denver, Colorado area medical cannabis activist Ken Gorman.^[39]

Researchers face similar challenges in obtaining medical cannabis for research trial. Recently, the US FDA has approved a number of cannabis research clinical trials, but the Drug Enforcement Agency has not granted licenses to the researchers in these studies.

Cannabis was listed in the United States Pharmacopeia from 1850 until 1942.^[40] The United States federal government does not currently recognize any legitimate medical use, although there are currently seven patients receiving cannabis for their various illnesses through the Compassionate Investigational New Drug program that was closed to new patients in 1991 by the George H. W. Bush administration. Francis L. Young, an administrative law judge with the United States Drug Enforcement Agency, in 1988, declared that "in its natural form, [cannabis] is one of the safest therapeutically active substances known."^[41] However, smoked cannabis is today not approved by the United States Food and Drug Administration (FDA).^[42] Twelve U.S. state laws currently allow for the medicinal use of cannabis,^[43] but the United States Supreme Court ruled that the federal government has the right to regulate and criminalize marijuana also in these states, even for medical purposes.

The term medical marijuana post-dates the U.S. Marijuana Tax Act of 1937, the effect of which made cannabis prescriptions illegal in the United States.

[edit] Alaska

The medical use of cannabis was endorsed by 58% of voters in Alaska in November 1998 and the law became effective on March 4, 1999. The law legalizes the possession, cultivation and use of cannabis for patients who have received a certificate from a doctor confirming they can benefit from the medical use of cannabis. The conditions and symptoms eligible are: cachexia, cancer, chronic pain, epilepsy and other conditions characterized by spasms, chronic glaucoma, HIV or AIDS, multiple sclerosis and nausea. The state maintains a confidential list of patients who are assigned an identity card.^[44]

[edit] California

Main article: California Proposition 215 (1996)

     California counties accepting applications for medical marijuana as of 3-25-08      California, U.S.A. counties not accepting applications as of 3-25-08

Information about medical cannabis in the U.S. western state of California can be found here: [11]. In 1996 California voted Proposition 215, also called the Compassionate Use Act, into law. CA Senate Bill 420 was passed in 2003 to clarify Proposition 215 by specifying statewide minimum limits on posession of marijuana and enact a Statewide Medical Marijuana ID Card Program. As of January 16, 2008, only 36 of 58 counties are issuing cards in the program, with 18,847 cards having been issued,^[45] however, participation in the ID Card program is optional and the identification card is not required to claim the Act's protections.^[46]

On November 5, 1996 56% of voters approved Proposition 215. The law removes state-level criminal penalties on the use, possession and cultivation of marijuana by patients who possess a "written or oral recommendation" from their physician that he or she "would benefit from medical marijuana." Patients diagnosed with any illness where the medical use of marijuana has been "deemed appropriate and has been recommended by a physician" are provided with legal protection under this act. Conditions typically covered by the law include: arthritis; cachexia; cancer; chronic pain; HIV or AIDS; epilepsy; migraine; and multiple sclerosis. No regulations regarding the amount of marijuana patients may possess and/or cultivate were provided by this act, though the California Legislature adopted guidelines in 2003.^[47] Obtaining a doctor's recommendation may be fairly simple.^[48]

[edit] Colorado

Information about medical marijuana in Colorado can be found here: [12]. On November 7, 2000, 54% of Colorado voters passed Amendment 20, which amends the Colorado State constitution to allow the medical use of marijuana.^[44] Patients can possess not more than 2 oz. (almost 57 g) of "usable marijuana" and not more than 6 marijuana plants, but they may neither take their medicine in public, nor even on their own property, if the public can see them taking it.^[44]

[edit] Hawaii

In Hawaii, Senate Bill 862 became law on June 14, 2000. Patients can possess a maximum of 1 ounce (28 g) of usable marijuana and a maximum of 7 marijuana plants. Information about medical marijuana in Hawaii is available at: [13].^[44]

[edit] Maine

On November 2, 1999, 62% of voters in the State of Maine (northeastern U.S.) passed Question 2. Patients or their primary physicians could possess a maximum of 1 1/4 ounces (35 g) of usable marijuana and a maximum of 6 plants. The law was amended when Maine Senate Bill 611 was signed into law on April 2, 2002, increasing the maximum quantity of usable marijuana a patient is allowed to possess to 2 1/2 ounces.^[44] Information about medical marijuana in Main is available at www.mainecommonsense.org.

[edit] Oregon

Main article: Oregon Medical Marijuana Act

Information about medical cannabis in the U.S. western state of Oregon can be found here: [14]. The Oregon medical cannabis program has the name, "The Oregon Medical Marijuana Program," which administers the Medical Marijuana Act approved there by the public in November of 1998.^[49] The Oregon Medical Marijuana Program administers the program within the Oregon Department of Human Services. As of April 1, 2008, there were 16,635 patients registered.^[50] Virtually all patients benefiting from the program say they suffer from "severe pain" and almost 2500 "nausea." The other conditions are given as epilepsy, AIDS / HIV, cancer, cachexia, chronic glaucoma and tremors caused by Alzheimer's disease.^[51]

[edit] State of Washington

The State of Washington (northwestern U.S.) adopted a law via elections in November 1998 (Initiative 692), legalizing the use, possession and cultivation of cannabis for patients with a medical certificate. The conditions are eligible the following: cachexia, cancer, HIV or AIDS, epilepsy, glaucoma, chronic pain otherwise intractable, and multiple sclerosis. According to the law in Washington [15], a patient prescribed medical marijuana may only keep a 60 day supply of it.^[52]

[edit] Legal and medical status of cannabis

Main article: Legal and medical status of cannabis

European laws on cannabis possession (small amount). Data are from multiple sources detailed on the full source list

Cannabis is in Schedule IV of the Single Convention on Narcotic Drugs, making it subject to special restrictions. Article 2 provides for the following, in reference to Schedule IV drugs:

A Party shall, if in its opinion the prevailing conditions in its country render it the most appropriate means of protecting the public health and welfare, prohibit the production, manufacture, export and import of, trade in, possession or use of any such drug except for amounts which may be necessary for medical and scientific research only, including clinical trials therewith to be conducted under or subject to the direct supervision and control of the Party.

This provision, while apparently providing for the limitation of cannabis to research purposes only, also seems to allow some latitude for nations to make their own judgments. The official Commentary on the Single Convention indicates that Parties are expected to make that judgment in good faith.

  • "Frequent marijuana use can cause airway injury, lung inflammation and impaired pulmonary defense against infection. The major potential pulmonary consequences of habitual marijuana use of particular relevance to patients with AIDS is superimposed pulmonary infection, which could be life threatening in the seriously immonocompromised patient. In view of the immonosuppressive effect of THC, the possibility that regular marijuana use could enhance progression of HIV infection itself needs to be considered, although this possibility remains unexplored to date."

  • "However, few controlled longitudinal epidemiological and immunological studies have been undertaken to correlate the immunosuppressive effects of marijuana smoke or cannabinoids on the incidence of infections or viral disease in humans. Clearly, additional investigation to resolve the long-term immunological consequences of cannabinoid and marijuana use as they relate to resistance to infections in humans is warranted."
