Abstract
Medical marijuana is now available in 23 states, and its growing acceptance has paved the way for the legalization of recreational marijuana. This article examines four recent campaigns to legalize recreational marijuana–two failures and two successes. Using data from newspaper sources, interviews with key players, and other sources, we examine the factors that influence whether a ballot initiative succeeds or fails. We identify similarities and differences between the four measures, the social forces shaping the debate, their claims and counterclaims, and a set of factors that appear to increase the odds that a recreational marijuana ballot measure will be successful.
