I think you're looking for, hugs not drugs, maybe?
Ha, but seriously, No. Yes alcohol is good for the cardiovascular (thins the blood doesn't it?) but that's all the further I'd go. Cigarettes are disgusting and I can't even remember what all goes into them though I've heard things like crayons and formaldehyde are fillers in it (CANCERWUT?).
Drugs are just stupid. Without them I'd venture to say there'd be a lot less gang wars and such bad things, though I suppose legalization would lend to that scarcity. Pot may not be as bad but I still wouldn't do it, it may have a significantly lower LD than other drugs but I've seen the kids in my school that really are addicted to it and they by far are the dumbest people I know. It may not kill you but pot really has no positive effects from my viewpoint. Pot isn't the only drug though you know. Meth, speed, crack, etc etc yeah, people are stupid and I lol heartily at drug addicts. I don't find the necessity in them.
I'm straightedge and I have more fun than anyone I know on drugs. ZOMG RUNNING FROM THE COPS THIS WEEKEND WAS TEH BEST!!11! I've gone to parties and been the only one that didn't drink and I just laughed at all the stupid drunk kids slurring and puking like the addicted idiots they are. More often than not, it's more fun to be the one that isn't on anything so you can mock those who are. :]
Well that's my 2 cents.
