Nowadays, a nice day in D.C. means the pungent stink of pot smoke wafting on a gentle breeze. And a trip to the farmers market can, if you’re so inclined, include a stop by the neighborhood cannabis pop-up, where your purchase of a $30 baseball cap, say, or $50 fanny pack comes with a “free gift” of cannabis-laced crackers.

Or, more straightforwardly, customers can buy an otherwise ordinary Bob Marley poster for $60, and receive up to an ounce of weed with it—the precise amount depends how many prints you buy. But an ounce is the legal limit for a casual, totally non-commercial transfer of recreational homegrown cannabis under a law the District of Columbia passed in 2015 called Initiative 71.
