Cannabis in Washington, D.C.

In Washington, D.C., cannabis is legal for both medical use and recreational use for possession, personal use, cultivation, transportation and gifting, and for retail sale once a regulatory system is implemented following an affirmative vote by the residents on a 2014 ballot initiative. The United States Congress exercises oversight over the government of the District of Columbia, preventing the local government from regulating cannabis sales like other jurisdictions with authority derived from a U.S. state.
