  1. Amphetamine

    Amphetamine is 1-phenylpropan-2-amine or C9H13N. It exists as two enantiomers: the levorotary form levamfetamine and dextrorotary form dexamfetamine. It is a psychostimulant drug of the phenethylamine class that produces increased wakefulness and focus in association with decreased fatigue and appetite. Amphetamine is used as a treatment for attention deficit hyperactivity disorder and narcolepsy, and is typically prescribed as amphetamine mixed salts or as dextroamphetamine. It has historically been used to treat obesity. Amphetamine increases activity related to the neurotransmitters dopamine and norepinephrine in the brain. This causes resistance to fatigue, elevation of mood, heightened libido, euphoria, and loss of appetite. Repeated high-dose exposure can lead to a mental state characterized by delusions, psychosis, and paranoia. The effects of amphetamines on serotonin transmission may contribute to hallucinations, appetite suppression, and hyperthermia. Recreational doses are generally far larger than prescribed therapeutic doses, and recreational use therefore carries far greater risk and far more serious side effects.
