I'm sorry, but I've had my day while in college as far as cannabis is concerned. The guy's looking for an excuse. Cannabis, otherwise known as marijuana, ain't it, as far as inducing psychotic rage. If he claimed it made him eat too much and get fat, he might have a point. Same goes for lazy and unmotivated. But psychotic rage? Bull.
We had ONE case of a guy going psycho after doing a joint when I was a cop--but the joint was laced with angel dust.
Ever see a guy break handcuffs? That nutbag did. (Broke his wrists, too, but we were too busy s***ting our pants to realize that.)
That is a common fallacy. There was a study done years ago on Peruvian farmers. One group did not smoke marijuana at all, a second group were "occasional" smokers and the third group were "very heavy" users.
They were run through a gamut of mental and physical tests.
The only difference the researchers could find was that the heavy users weighed an average of 10 pounds LESS than the other two groups.
I always figured they were just too zoned to eat!
But dude, the guy was like, totally harshing his mellow by bogarting the nachos and red bull. Wouldn't you be pissed?
