Dexedrine, a brand name for the medication dextroamphetamine, treats narcolepsy and attention deficit hyperactivity disorder, or ADHD. It works by affecting the chemicals of the brain that contribute to impulse control and hyperactivity. Dexedrine is an amphetamine.

Amphetamines are stimulants that speed up the body’s system. Amphetamines can look like pills or powder. Common prescription amphetamines include Adderall® and Dexedrine®.

Amphetamines are generally taken orally or injected. However, the addition of “ice,” the slang name of crystallized methamphetamine hydrochloride, has promoted smoking as another mode of administration. Just as “crack” is smokable cocaine, “ice” is smokable methamphetamine.

Effect on the Mind
The effects of amphetamines and methamphetamine are similar to cocaine, but their onset is slower and their duration is longer. In contrast to cocaine, which is quickly removed from the brain and is almost completely metabolized, methamphetamine remains in the central nervous system longer, and a larger percentage of the drug remains unchanged in the body, producing prolonged stimulant effects. Chronic abuse produces a psychosis that resembles schizophrenia and is characterized by paranoia, picking at the skin, preoccupation with one’s own thoughts, and auditory and visual hallucinations. Violent and erratic behavior is frequently seen among chronic abusers of amphetamines and methamphetamine.

Effect on the Body
Physical effects of amphetamine use include increased blood pressure and pulse rates, insomnia, loss of appetite, and physical exhaustion. Overdose effects include agitation, increased body temperature, hallucinations, convulsions, and possible death.
