First let me say that reports of folks sitting in jail for having a little bit of pot are, for the most part, erroneous.
It's just like the press reports about the McDonald's spilled coffee case. It's just not reality. Jack - if you want to cite some specific cases, I'll reconsider my position. I don't know of anyone sitting in jail on a pot charge.
While I can't say I am in favor of legalizing it, I am in favor of de-criminalizing pot. I'd like to see Joe Average be able to possess an ounce or less without fear of getting arrested. Maybe that's just semantics.
Now - smoking it in public would be verbotten - as is usually the case with drinking. Other, reasonable restrictions would apply.
Being a libertarian, I think that which governs least governs best. More expense and damage has been suffered than is justifiable in combatting the (percieved) evil of pot use.
Not a single study exists showing a causal connection between pot use and any long term adverse effects. The worst that could be proved was what is known as A-Motivational Syndrome. That means after you burn one, you are more inclined to lay on the sofa and watch M-TV than to go out and cut the lawn, or do something productive.
Drugs and crime are often tied together, but killing is over drug turf and almost always centers around the hard drugs (crack, coke, heroin).
Really - who knows somebody that smoked a joint and went on a violent rampage? The worst I ever did was go to 7-11 and attack an ice-cream cone with malice aforethought.
The government should provide services (like trash disposal and fire departments), protect the property of its citizens and defend the country against foreign threats. besides that, they shoudl mind their owned damned business. Unfortunately, they think everything we do is their business.
