MADD is trying to steal them.
Its not a big deal but I thought I'd point it out since you'd want to think about this, but you keep saying that we wouldnt see a huge festival of weed smoking if it were legalized since we dont see that towards other drugs. Technically we have huge festivals with beer tents (one a month in my hometown) that could argue against what you are saying.
Of course, I think a huge part of the binge drinking culture is due to us jumping right into the world of drinking irresponsibly as adults or secretly as young adults rather than learning from our parents/other adults like we do about other important yet potentially abused facts of life (pain meds/eating healthy/driving safe/etc.).
