Let's be real the big problems from people are people who can't control themselves. Often combining weed with alchohol. Maybe wrong but stoners who only smoke don't go into THC fueled rages, don't steal to support a habit,don't beat up people. Tend to be mellow,laid back and live accordingly. People who drink and get drunk, tend to be loud, prone to violence and destructive. I mean why exactly is the private consumption of weed so scary to folks. I just dont get it.
