Methamphetamine
What Kind of Drug Is It?
Methamphetamine, commonly referred to as "meth," is a synthetic, or laboratory-made, stimulant. Stimulants increase alertness, endurance, and feelings of well-being in the user. Examples of other stimulant drugs include cocaine and caffeine. (Entries on both of these drugs are available in this encyclopedia.) Methamphetamine is considered an especially powerful and addictive substance—far more addictive even than cocaine—because of its powerful effect on the brain.
Methamphetamine was developed by a Japanese chemist in 1919 from amphetamine, another laboratory-made drug. Amphetamine increases energy, reduces appetite, and helps keep users awake. (An entry on amphetamines is also available in this encyclopedia.) The first amphetamine had been made by a German chemist in the late 1880s, but it was not used for medical purposes until decades later. In its earliest form, amphetamine was found to be an effective treatment for asthma (AZ-muh), a lung disorder that interferes with normal breathing. Because of its similar ability to unclog breathing passages, methamphetamine was originally used as a nasal decongestant.
As of 2005, the medical use of methamphetamine was extremely limited. However, illicit, or unlawful, use was quite high worldwide. Like other amphetamines, methamphetamine boosts energy levels and produces an intense rush or high in the user.
