Amphetamine (alpha-methyl-phenethylamine), also known as speed or crank, is a stimulant, and club drug, used to diminish the appetite, control weight, and treat disorders including narcolepsy and attention-deficit hyperactivity disorder. It is also used recreationally and for performance enhancement (these uses are illegal in some countries).
|When used within the recommended doses, side-effects like loss of appetite tend to decrease over time. However, amphetamines last longer in the body than methylphenidate (Ritalin, Concerta, etc.), and tend to have stronger side-effects on appetite and sleep.|
|Amphetamines are also a standard treatment for narcolepsy as well as other sleeping disorders. They are generally effective over long periods of time without producing addiction or physical dependence.|
|Amphetamines are sometimes used to augment anti-depressant therapy in treatment-resistant depression.|
|Medical use for weight loss is still approved in some countries, but is regarded as obsolete and dangerous in, for example, the United States.|
