Speed (methamphetamine, C10H15N) is a potent and addictive central nervous system stimulant, chemically related to amphetamine, but with greater central nervous system side effects. It is a white, odorless, bitter-tasting powder that easily dissolves in water or alcohol.
Methamphetamine is classified as a Schedule II stimulant by the U.S. Drug Enforcement Agency (DEA), which means it has a high potential for abuse and is available legally only by prescription. When abused, it is commonly referred to as “speed”, “meth”, or “chalk” and has been in use since the early 1960s. When abused, methamphetamine is usually smoked, snorted, injected, or taken orally.
Medically, methamphetamine has been used for the treatment of attention deficit hyperactivity disorder (ADHD) and obesity, but these uses are limited in the U.S. due to the high potential for abuse, addiction, and channeling to illicit drug markets. Prescription doses are typically much lower than those used illegally. In the U.S., methamphetamine is available by prescription as the brand name product Desoxyn or generically. Only the 5 mg oral tablet is available.What is
