Just as Canada made a sweeping decision to fully legalize marijuana, former Mexican President Vicente Fox made headlines of his own after joining the board of “High Times”, a publication that has carried the crusade for cannabis legalization since its inception. In an interview with the Associated Press, Fox argues in favor of extending legalization not just to marijuana but to all so-called street drugs. Fox cites as a reason for his position the brutality associated with the illegal drug trades. Government cannot successfully regulate people’s behavior, he argues, and so individuals ought to be free to do what they wish without fear of criminal repercussion.

Fox’s support of drug legalization is no longer the minority opinion it once was among national leaders. In the U.S., eight states — Alaska, Washington, Oregon, Nevada, California, Colorado, Maine and Vermont — have legalized recreational marijuana. Lawmakers are increasingly supportive of marijuana legalization not just as a means to relieve prison overcrowding but as another source of jobs, tax and investment revenue. When it comes to an across-the-board legalization at the federal level, however, a wait-and-see approach ought to be embraced. Why? Because early evidence in the wake of successful State-based decriminalization initiatives reveal problems policymakers have yet to resolve.
