Bring It On; Tax Us

Jeremy Singer-Vine tries to figure out how taxing pot fits into the legalization debate:

Whatever they do, governments that tax marijuana will have to balance a trio of related goalsreducing budget deficits, eradicating the black market, and improving public health. Inevitably, one goal will get the short end of the spliff. Harvard's Miron predicts that governments will give priority to reducing deficits in the current round of pot-reform debates. It's not the best argument for legalization, says Miron, who has estimated that U.S. governments could save almost $13 billion annually if they no longer arrested, prosecuted, or imprisoned marijuana buyers or sellers. But in an era of falling tax revenue, it may be the most effective one.
