Excellent point, never thought of it that way before. Beer is, I think, more or less the same as "drugs"...ok, yes, there are many differences which we all realize, etc.....but the point is, have you ever heard of, or does it even seem conceivable, that someone could get killed in the "beer trade"??
And to those who say "it's different"...yes, it is....I can list any number incidents involving potential serious societal harm, and some involving actual societal harm, that were totally a result of alcohol. And make no mistake, these people also had access to the full range of commonly available drugs as well, and partaked of them often. But in the aggregate, in my experience, it is rarely the drugs that causes the problem, it is almost always the booze. The argument is that all these social incidents come from booze, but it would be worse if drugs were also available.....well drugs ARE available...if you want drugs, it is only a little bit more difficult to buy than booze.
Although, it seems reasonable to me that if "drugs" are legalized, a larger portion of the public will get involved, but I haven't seen anything to make me think this will make society worse. My best guess would be that it might get people off the booze a bit and chill them out, so they don't start so many fights and other wild adventures that boozed up people get involved in.
