You can't legalize pot. I'll tell you why.
Because pot as it stands right now works. If you want it, you can get it, and it's cheap. Legalizing it would do very little for the coffers.
Also it isn't socially acceptable yet, imagine going to the grocery store and seeing packs of joints advertised next the the cigarettes.
There's more detail to it all, but it works right now. I did but don't anymore, and California passed a law last year stating anything under an ounce is a misdemeanor with a 100 dollar fine.
That has acctually helped alot with court costs.
