What is the different between marijuana and alcohol?

Doesn't matter stay away from both unless you wanna end up in prison.

There are several differences between marijuana and alcohol. Marijuana is usually smoked, and alcohol is consumed by drinking it. (It is also possible to drink marijuana if you brew it into a tea, but that is not the most common method.) Marijuana is illegal (and even though some states have legalized it, the US federal government has not legalized it) and alcohol is legal, except in Muslim countries where it is prohibited. Smoking marijuana is dangerous to your lungs, and drinking alcohol is dangerous to your liver.
