This would be the greatest marketing trick ever played on an unsuspecting public. The price would shoot up to the point where drug cartels might deal exclusively in pot. Look at how much some people are taxed on cigarettes: http://tobaccofreekids.org/research/factsheets/pdf/0267.pdf Now imagine that tacked on to the price of your weed. You'll go running back to your street dealer. Plus, you just told your kids that drugs are OK because you legalized them. Once you legalize pot, the offense for bringing it over the border will vanish. Cartels could do as they please out in the open. What is the worst that could happen to a typical drug pushing scumbag. Tax-evasion? Big deal. Most border jumpers are experts at that already. So yeah. Legalize it. Every country that has is going through a phase of dehumanization. Prostitution and the sex trades now becomes a way of life. That is too high a price to pay.
