If you take a drive along just about any commercial strip in Denver, it won't be long before you see an old convenience store or bar that's been converted into a medical marijuana dispensary. The number of dispensaries has boomed in the last year or so, prompting action from Colorado lawmakers. And now, a one-year moratorium on issuing business licenses to medical marijuana operations has gone into effect (via 7News [2]). The state is currently home to some 1,100 dispensaries, and 9News [3] is reporting that by this time next month, as many as half of them could shut down. Not only is there a moratorium on new businesses, but dispensary owners, contending with a lengthy paperwork process, must submit state registration information by August 1 that could cost them $7,500 to $18,000. [4] The Denver Post [4], meanwhile, points out that a dispensary in Denver's River North neighborhood has gone up for sale---on eBay---as the deadline approaches.
