Drugs can have many different effects on a person's health. Some drugs cause many people to die every year. Tobacco and alcohol can cause death. Other drugs do not cause death. Cannabis and psilocybin mushrooms ("magic mushrooms") do not cause death. But all drugs affect one's health. Someone using drugs is "intoxicated." Intoxicated people may do dangerous things. They may be unable to safely drive or operate machinery. If an intoxicated person operates machinery, an accident may occur.
