With the passing of Initiative 71 in March of 2014, Washington, D.C. joined a host of states legalizing adult recreational use cannabis. The measure went into full effect February 26, 2015, legalizing the possession of up to two ounces of cannabis, allowing D.C. residents to grow up to three mature and three immature cannabis plants in their residencies, and transfer up to one ounce of cannabis to another individual.

Although recreational sales are currently prohibited, the municipality is one of the few places to set no exclusive list of qualifying conditions for medical users, and allows doctors to prescribe cannabis as a treatment for any ailment they feel will benefit from its use.  In April of 2018, the district began extending reciprocity to 17 additional states making it one of the most welcoming areas for traveling medical patients.
