In my latest Forbes column, I compare marijuana legalization in Colorado and Washington with the policies embodied in three initiatives on the ballot this year. Here is how the piece begins:
This week a marijuana legalization initiative officially qualified for the ballot in Oregon. Voters will also consider legalization measures in Alaska and (probably) the District of Columbia this fall, so by the end of the year three more jurisdictions could join Colorado and Washington in allowing recreational use of cannabis. The differences among the five measures illustrate the advantages of federalism, which allows policy experiments that will help chart the course to the end of marijuana prohibition in America.
