My experience is just the opposite. Habitual pot users are the angriest, rudest and deceitful group of people I've known. I've been around drinkers thousands of times and the worst behavior I've witnessed is loud talking.
A lot of them are sex perverts...
I guess personal opinion is relative...i, on the other hand, have watched, many times, drunks fighting ( i was one of them)...
Never did my friends and i, when stoned or baked out of our minds ,conjure up ill feelings towards one another or go out to look for trouble. NEVER!...
Mind you i dont drink or smoke anymore, but , other than being in Compton where you're ready to shoot anyone that owes you 200 bucks for an ounce, i've hardly seen or heard any violent tendancies with habitual pot smokers...
I would wager that at least one part of this statement is a lie.
