After thought:

I think it's purely a case of responsibility. People should be able to realise when they're smoking too much. Weed is the bomb, but people who abuse it and turn into vegetables (like my mate) create the negativity that surrounds it. Then again, it's the same as alcohol, if you can't handle your intake, just put the shite down or you'll hurt yourself. Know what I mean!

Don't get me wrong, i'd be toking a fatty as I typed if I didn't have A level exams in less then a month !
