So the results of pot smoking are unpredictable; i.e. some will kill their neighbors and others will not?
Well, nothing is 100% predictable. Not even sober people.
But I'd say 95%+ of people are far less inclined to be angry or violent on pot. Maybe 4%+ stay the same and a very very small group actually become more angry. I've met hundreds of pot smokers and nobody has ever heard of anyone becoming directly violent from it.
Booze is FAR more likely to directly incite aggression and violence. Countless people I've met become violent 100% of the time they get drunk and have domestic violence rap-sheets a mile long. Two of them actually stopped drinking and switched to pot which eliminated the violence.
Unpredictable...a lot like people that don’t smoke it
