It may seem strange, but on 1 January 2014 it became legal to buy marijuana in the US state of Colorado. That’s right, you could legally buy pot from a store and not get arrested. This groundbreaking event was obviously big local news and The Denver Post responded by creating the first section in a US newspaper, The Cannabist, devoted entirely to pot: its production, its sale, strain reviews, recipes, you name it. The newspaper appointed an editor to oversee the section, Ricardo Baca, who surrounded himself with freelance journalists and in-house staffers with, shall we say, an affinity for the project. All this is covered in Mitch Dickman’s entertaining, wickedly funny documentary that tells the story of what might be regarded as a desperate ploy to boost sales, or an extraordinarily relevant reaction to a new social phenomenon – you decide. But when you do, ask yourself this question first: are you high?
