Legalization could slash the price of pot 80%

I'm hoping that it might make it so that Mexican people don't have to teach their children things like this in school. The monetary amount is secondary. The cost in ruined lives over a drug that is much less harmful than alcohol is the toll that bothers me. I can't dig up statistics right now but I would venture to say that yes, because most of the drugs coming over the border are NOT cocaine, heroin, methamphetamine, or even fake prescription stuff that this might put a big dent in the cartel profits and slow down the murders. So what if it puts some useless rich kid pot dealers out of business?
