Learn about the effects of marijuana, how overdose works, and the risks involved especially for teenagers, including safe practices and signs of overdose.
Marijuana, also called cannabis, contains a chemical called THC that affects the brain and body. While marijuana is not known to cause fatal overdose like some other drugs, it is possible to take too much and experience unpleasant and potentially dangerous effects.

If marijuana is used, understanding the risks and watching for overdose-like symptoms is important.
