It's perfectly fine for us all to play GTA, a game that glorifies mass slaughtering and robbing people, carjacking, drug dealing, and masses of other horrific actions, but god forbid we even discuss cannabis (which, may I add, is less harmful then tobacco and alcohol). I smoke it quite alot - I get good grades in school, I have a lot of friends.. I don't understand peoples' gripe on this herb.
No-one's encouraging it, no-one's making any rebellious point - I personally do it because it's an enjoyable and social experience. Nothing more, nothing less. If this was a discussion on something like cocaine or heroin, there would obviously be (and with good reason) cause for concern.
