A toke might make things feel a little simpler, but there's no denying that marijuana laws are downright complicated. While marijuana is legal for recreational use in nine states and the District of Columbia, that could mean anything from dispensaries on every block to a complicated system of "gifting" pot. And medical marijuana? In some states that means anyone with a sore foot can legally buy a bag of green, while in others it means that only severely ill patients – those who suffer from diseases like cancer, AIDS, or multiple sclerosis – have access to oils and tinctures. Even in states where it's still entirely illegal, sometimes getting caught with pot can mean the cost of a parking ticket, while other times it can mean a year behind bars.
Confused? We were, too. With that in mind, here's a brief state-by-state guide to weed across America.

In 2014, voters passed a ballot initiative that made recreational, adult-use marijuana legal in the nation's capital.
