Methamphetamine is one type of amphetamine. In pure form it is a near white powder, but it may appear in many different colors, and its texture may range from powder to crystals or tablets, depending on the method of production. It can be smoked, snorted, injected, or taken orally.
Side effects are similar to other amphetamines, including elevated heart rate, blood pressure and respiratory rate, decreased appetite, aggression, paranoia, depression and irritability. High doses may cause hallucinations or delusions. Long term effects also include malnutrition, psychosis, kidney and other tissue damage, memory loss, anxiety, auditory hallucinations, cardiac and neurological damage. Overdose may cause hyperthermia or convulsions, which can lead to death. Methamphetamine is highly addictive.
