I'm no friend to marijuana. I've never used it, don't like the smell of it, and generally don't like the subculture around it. But with that said, the persecution of this fairly minor activity messes up too many lives and wastes too many of society's resources.

Ultimately it is no worse to society than alcohol consumption, and I'm not in favor of banning alcohol either.

But hold people accountable for impairment and disruption. If you are caught driving a car high it should be punished just like driving one drunk.
