Marijuana is one of the most frequently abused psychoactive drugs.
Its main ingredient changes the way information reaches and is acted upon by the brain.

A hallucinogen(huh LOO sih nuh jun) is a drug that distorts perception, thought, and mood.
Hallucinogens overload the brain with sensory information, causing a distorted sense of reality.
The strongest known hallucinogen is lysergic acid diethylamide, or LSD.
LSD’s effects are unpredictable—it can either stimulate or depress the central nervous system.

Steroids can make a user’s personality very aggressive.
Some steroid users become severely depressed.
