Amphetamine refers to a colorless, volatile liquid, C9H13N, used primarily as a central nervous system stimulant.

Amphetamines are powerful stimulants of the central nervous system, producing feelings of euphoria, alertness, mental clarity and increased energy lasting for 2 to 12 hours depending on the dose. The downsides are increased heart rate and blood pressure, nausea, irritability and jitteriness, plus fatigue once the effects have worn off. Overdosing can lead to convulsions, heart failure, coma and death. The fatal dose varies from person to person, with some reports of acute reactions to as little as 2 milligrams and others of non-fatal 500-milligram doses. Most deaths from overdose have been among injecting users. Their principal effect is to block dopamine transporters, which leads to higher-than-normal levels of the pleasure chemical dopamine in the brain.
