anyone who thinks that legalizing marijuana will stop people slangin chron is a fucking retard. there will ALWAYS be private growers who will undercut the government prices because there will be money to be made there. and guess what? where there is large amounts of money to be made, there will be crime. i think it will be significantly less than there is now, but it will definitely still exists.
and you say that the probation system is chocked full of stoners, but you don't think the prison system isn't too?
"(2007) According to the American Corrections Association, the average daily cost per state prison inmate per day in the US is $67.55. State prisons held 253,300 inmates for drug offenses in 2007. That means states spent approximately $17,110,415 per day to imprison drug offenders, or $6,245,301,475 per year."
