Alcohol was illegal at one time, does that make it bad? I might have stayed in the Borg much longer if I hadn't started smoking pot. It's always helped me with reflection. I've made some of my best decisions high. Sometimes I smoke everyday, sometimes I go weeks or months without it.
Personally, the last thing I want is the government to start regulating and taxing my weed. Price will go up, quality will go down...
I live in Canada, and I think it isn't viewed as critically here. Legalizing it would significantly decrease the amount of drug related crime that happens. The dealers here trade it across the border for the harder stuff. Pound for pound. There are also medicinal growers here, and you can get a prescription from your Dr. for medicinal weed. Compassionate Care they call it, and it's used to treat cancer, arthritis patients and others who suffer from chronic pain.
The world would be a calmer place if everyone smoked a bowl once in awhile.
