Methamphetamine is a strong physical and mental stimulant. It is legally prescribed as a treatment for ADD under the brand name Desoxyn, for both children and adults. Recreationally, methamphetamine is used to increase sexual drive, lift the mood, and increase energy, allowing some users to engage in sexual activity continuously for several days straight. Methamphetamine production is a relatively simple process, especially when compared to many other recreational drugs which has contributed to its widespread use. It is frequently reported on in the media when home meth-producing labs are busted.
Methamphetamine exists as two enantiomers, dextrorotary and levorotary. Dextromethamphetamine is a stronger central nervous system(CNSCentral Nervous System) stimulant than levomethamphetamine; however, both are addictive and produce the same toxicity symptoms at high doses. Methamphetamine may be sold illegally, either as pure dextromethamphetamine or in an equal parts mixture of the right and left handed molecules (i.e., 50% levomethamphetamine and 50% dextromethamphetamine). Both dextromethamphetamine and racemic methamphetamine are schedule II controlled substances in the United States. Similarly, the production, distribution, sale, and possession of methamphetamine is restricted or illegal in many other countries due to its placement in schedule II of the United Nations Convention on Psychotropic Substancestreaty. In contrast, levomethamphetamine is an over-the-counter drug in the United States.
