How is it bad?
Alcohol is a drug that goes directly from your digestive system into your blood and within a several minutes it spreads to your entire body! Alcohol is considered a depressant but most people drink for the stimulant effect. But if someone consumes more than the body can handle then its considered a depressant. In some part of America alcohol is still illegal but in most parts of America its legal.
Marijuana is the most common illegal drug around. It comes from a plant called "cannabis." Marijuana is legal in few states but over all it is illegal. Marijuana is a stimulant and depressant. It depends.
