I would rather see grass sold than alcohol any day... While both substances alter people's cognitive abilities, I have yet to see two smokers out in an alley duking it out... (By the time they have made their way to the alley, they can't even remember what they were mad about and have probably become friends during the walk...)
Hippy hay rarely leads to anger and violence...
That is the main reason I would rather see grass on the market in place of alcohol.
