Effects of other drugs
Marijuana: Marijuana and related compounds are usually used for their "relaxation" effects or to produce an altered sense of reality, a "high". Marijuana is usually smoked, and like tobacco, it is very toxic to the lungs. Disorders of memory (loss) and of mood often occur in chronic users.
Cocaine (stimulant). Cocaine, crack, and related forms are usually used for stimulation and to produce a sense of euphoria. All forms of cocaine are highly addictive, producing a habit that is extremely difficult to stop. In some individuals, cocaine may produce fatal cardiac rhythm disturbances.
Amphetamines (stimulants): Amphetamines, and their new derivatives "crystal", "ice", and Ecstasy, are used for stimulation. These compounds are very addictive and may produce psychotic and violent behaviors.
LSD & PCP (hallucinogens): These chemicals are used to produce "altered states" to escape reality. They are very dangerous and can cause psychosis.
Valium, Barbiturates, etc. (depressants): These and other prescription drugs of this type are usually used for their sedative or hypnotic effects. Some of these drugs are highly addictive, and others can cause seizures (convulsions) in individuals who take them over long periods of time. These drugs can be fatal if mixed with alcohol or other depressants.
Heroin, Codeine, etc. (narcotics): These are some of the most addictive substances known. They produce a high or euphoria. Withdrawal can produce convulsions or even coma. Overdose is common and can result in death. Needle-drug users are in a high-risk group for infection with human immunodeficiency virus (HIV), the cause of AIDS.
Other: Many medications and drugs have the potential for abuse. If you have concerns or questions, ask for professional advice.
