Levmetamfetamine (other names: l-desoxyephedrine, l-methamphetamine, levo-methamphetamine) is the l- stereoisomer of methamphetamine, a sympathomimetic vasoconstrictor which may be used in over-the-counter nasal decongestants. The common brand-name for levmetamfetamine in the U.S. is the Vicks Inhaler. The name was converted to levmetamfetamine, from levo-methamphetamine to lower the risks of abuse of this chemical. Although sometimes called levo-desoxyephedrine, ephedrine is also well known, both as a stimulant and as a precursor to methamphetamine and methcathinone. It is also in a popular drug Adderall commonly used for treatment of ADD.

L-methamphetamine alone can raise blood pressure and cause the heart to beat rapidly due to its effects mimicking the sympathetic nervous system, but is not thought to be nearly as addictive or centrally active as the d- isomer of methamphetamine. Its common side effects include muscle tremors and stomach cramps. Furthermore, by ingesting the cotton contents inside the inhaler, one also ingests menthol and camphor, both analgesics lethal at high doses
