Beau Kilmer on restricting cannabis marketing

Beau Kilmer has a very sharp short op-ed in the NYT arguing for the use of federal muscle to limit aggressive cannabis marketing and child-friendly packaging in Colorado and Washington. Going after sellers of cannabis candy seems like clearly good idea, given the risk of accidental consumption by little children. Would it really be too great an imposition to insist that cannabis edibles and potables be unsweetened and not look like confections? Since the Supreme Court’s “commercial free speech” doctrine is based on making truthful claims about lawful products, and since cannabis remains an unlawful product at the federal level, I don’t see the basis for claiming that the legalizing states and the federal government have to permit the same sort of unscrupulous advertising for cannabis as they do for alcohol.
