strung out people are not productive people, though... productive people go to work and pay taxes. strung out people kill and steal to get their next fix. i'm speaking strictly about hard core drugs, such as crack and meth. coke is the white rich man's poison, it doesn't really apply, but major street drugs and stove-top crank, yeah... gets a lot of people screwed up and hardly any of them can hold down a 40 hr/wk job.
then you have your pill abusers. taking umpteen loritabs (sp), costly, leads to theft (stealing out your grandma's medicine cabinet) ...
crime anyway is the end result of this choice in legislation, at least that's been the argument against. and it's not as if it couldn't work, other countries have legal what we do not. it's american's that fail. they always seem to screw up a good thing.
