You miss the point. Kids often use alcohol because of the same reason as adults.. it reduces inhibition. Kids who use marijuana are often the lazy ones. Not really the "drug" of choice for a party enviroment. Obviously you don't understand the effects or the difference between the two or you wouldn't of made such an off base statement.
Oh man. If you're looking for "it reduces inhibition", there's cocaine, crack, methamphetamine, GHB, Ecstasy, Rohypnol, and many others. Yet the #1 drug of choice (by 2:1 over marijuana), alcohol.
Alcohol in a party environment? Like a rave?
And this is the only time kids do alcohol -- at a party? Nope, I still say they do it because it's approved for adults. They use anything else and they're loser dopers.
