These votes suggest what may be a spreading, geographic Humboldt of the mind, in which the liberties of pot in far-northern California, and the unusually ambiguous legal regime there, metastasize around the country. If you live in Seattle and sell licensed marijuana, your operation could be perfectly legal from the perspective of the state government and committing a federal crime at the same time. It is hard to detect much political enthusiasm for a federal pot crackdown, but the complexities that come with these new laws may be hard for Washington to simply ignore. What happens, for instance, when a New York dealer secures a license and a storefront in Denver, and then illegally ships the weed back home? Economists who have studied these questions thoroughly say that they can’t rule out a scenario in which little changes in the consumption of pot—the same people will smoke who always have. But they also can’t rule out a scenario in which consumption doubles, or more than doubles, and pot is not so much less prevalent than alcohol.
