MJ is also very popular with the two most violent American demographics.
But so what?..........just smoke (or now eat) away to your hearts content. MJ is harmless say its strongest advocates, and how can they be wrong? They say it has no harmful side effects, SO THERE!!! They're using strong, anecdotal evidence which is obviously far superior and more persuasive than scientific studies.
So who do you want to believe......the stoners who think a strong drug has no harmful side effects, or the numerous studies of recent years done by reputable scientists and analysts showing otherwise?
