I don't think marijuana possession or use in limited quantities should be criminal. I know of a couple of cases where someone who used pot had severe psychological problems there after, but I've also known people who had similar problems from alcohol.

Like alcohol, however, marijuana is not risk free, as you point out.

The way I would approach decriminalization would be to make it clear that any voluntary use (I suppose someone could eat a pot brownie without knowing it had pot in it ... I did once in the early '60s) means you (or your parents if you are underage) accept complete personal responsibility for all negative consequences, including health problems, accidents, etc., etc. And, driving under the influence should result in permanent loss of driving privileges.

Punish the actual negative behavior, not the casual smoker.

Driving is a right not a privilege.
