Methamphetamine is a stimulant drug which is quickly metabolized to amphetamine. It is used in pill form, or in powdered form by snorting or injecting. Crystallized methamphetamine is inhaled by smoking and is a considerably more powerful form of the drug. Methamphetamine use can cause irreversible damage to the brain, producing strokes and convulsions, which can lead to death. Ecstasy, a new trendy and popular drug among teenagers is a refined and processed form of methamphetamine.
Opiates are any of the addictive narcotic drugs.
The opiates include drugs such as morphine, heroin and codeine. Opiates can reduce attention, sensory and motor abilities, produce irrational behavior, depression, paranoia, and other psychological abnormalities. The effects of this drug are unpredictable and variable. PCP use can lead to paranoia and extreme irrational behavior. Once popular, PCP use has declined dramatically in recent years and is no longer considered a major drug of abuse.
