I think alcohol is socially acceptable because when people fuck up, they have something to blame it on..when people are assholes to each other, they have something to blame it on.. "Oh you cant hold that against him, he was drunk." an argument that's made thousands of times each day and night, rarely when people are smoking weed is there an argument or a fight, where in bars and alcohol related situations its very common to see people arguing over bogus stuff and not considering what anyone else has to say... i'm not saying alcohol is bad.. for me, but it is for some people who cant handle drinking in moderation.. this is the same for smoking, you can smoke all you want, enjoy it as much as you want, but if your burning out its your fault, the burn out cant be held as the stereotype for cannabis users because not all cannabis users are like that, most of them can use the "drug" in moderation and still maintain a balanced lifestyle..
if anything, a balanced lifestyle is the best way to go in my opinion.. why smoke weed? because it makes you feel fucking awesome and relaxed, especially at the end of a day where you worked hard at something or at a time when you really need to relax, thats why people smoke pot.
