If America’s first marijuana legalization experiment is any indication, the end of prohibition can start smoothly. Since retail sales of recreational marijuana began in Colorado, revenues from marijuana sales have continued trending up. At the same time, crime in Denver, home of most recreational marijuana shops in the state, has dropped nearly across the board. Colorado and Denver’s experiment with legalization is, in other words, going well. The state is seeing its coffers filled with some extra revenue, as expected. And crime, despite warnings from law enforcement officials, isn’t rising.
