There are 3 main groups of drugs: depressants, stimulants, and hallucinogens. Click on each link to find out more information.
Depressants slow down or depress the central nervous system, making people feel more relaxed and less conscious of their surroundings.
Stimulants excite or speed up the central nervous system, making people feel more alert and energetic while decreasing their appetite.
Hallucinogens dramatically affect perception, emotions, and mental processes by distorting the senses and causing hallucinations.
