ALCOHOL HAS NO BIOLOGICAL CONNECTION TO ABUSE OR VIOLENCEAlcohol does not directly make people belligerent, aggressive, or violent. There is evidence that certain chemicals can cause violent behavior — anabolic steroids, for example, or crack cocaine — but alcohol is not among them. In the human body, alcohol is actually a depressant, a substance that rarely causes aggression. Marijuana similarly has no biological action connected to abusiveness.
