Judging by the high percentage of criminals who have it in their bloodstream when arrested, pot is definitely the choice of criminals, I guess criminal types, and the crime of illegal drugs go hand in hand.
Yes, pot increases violence behavior. In the 70s, my girlfriend smoke it, did the big chicken, starting running after cars, jumping on their hoods, attempting to get at the occupants. They found her on my neighbors back porch eating dog food.
