Classification of Drugs
- There are three basic categories of drugs, classified by their effect on the central nervous system:
- Depressant drugs
- Stimulant drugs
- Hallucinogenic drugs
Depressant Drugs
- Depressant drugs slow down the central nervous system reactions.
- Examples:
- Narcotic drugs (opium, morphine, heroin, codeine, analgesics)
- Non-narcotic depressants (barbiturates, tranquilizers, alcohol)
- Possible side effects:
- Slurred speech
- Disorientation
- Drunken behavior without the odor of alcohol
Stimulant Drugs
- Stimulant drugs increase the central nervous system reactions.
- Examples:
- Anorectic drugs (diet pills/weight control)
- Amphetamine drugs (biphetamine, dexedrine)
- Cocaine (local anesthetic)
- Possible effects:
- Increased alertness
- Excitation
- Euphoria
- Increased pulse rate and blood pressure
- Insomnia
- Loss of appetite
Hallucinogenic Drugs

- Examples:
- LSD (lysergic acid diethylamide)
