How is it you think only people who’s political views are left of center believe current marijuana laws need to be changed??
First things first: The comment is facetious. (The smiley, if you were paying attention, would've gave that away.)
But that aside, you bring up an interesting point.
Just for the record, I don't think it's "only" people on the left who think it's a good idea. I'm on the right and I actually think it's a good idea. In fact, I think the same kind of legislation should be extended to all drugs. I have my reasons for this position which I wont go into detail at this point. Suffice to say, I believe that taking the criminalization part out of the addiction equation would go miles toward helping people who have additions in secret, to come out in the open and possibly seek help.
As for the left of center part, one need only place a demographic chart up against a political map and the strong correlation will become quite self evident. Where are the Democrats most popular? Where is marijuana currently legal? Where is the marijuana agenda being pushed? Where is it getting the strongest reception? Rejection? Get the point?
