To be honest like most things, I don't give a fuck about drugs, getting drunk or gambling as such, and most of the people I've seen who actually toke a lot were cunts to me. I'm not going to moan on about legalizing that shit or medical Marijuana use (unless you have peer reviewed articles on what it supposedly treats apart from Glaucoma that they always bring up, that would be an interesting read).
I'm not going to moan about gateway drugs and that whole nice guy smoked one spliff now a grade A cunt on Heroin, type yellow press that they push in the Mail, cos most people I knew aren't like that.
In fact the best advert for not doing drugs is this, do drugs and you'll end up with the memory of a gnat. There are a few people I know who's short term memory is all over the place due to drugs and that. Also if you do drugs you'll end up a cunt but we all know that already.
