District of Columbia is one of the few places that allow marijuana for personal use.
Residents 21 years or older may legally possess up to 2 oz of marijuana for personal use and grow no more than 6 plants (with up to 3 mature). Possessing more than 2 oz is a misdemeanor, penalties for which include a $1,000 fine and a 6-month imprisonment.
Persons are also allowed to transfer without payment no more than 1 oz to other adults and use or sell drug paraphernalia related to the use, growing, or processing cannabis. Selling between 1 oz and 0.5 pounds is a crime, punishable by a $1,000 fine and a 6-month incarceration. A subsequent offense increases the penalties. Furthermore, sale within 1,000 feet of a school zone may bring a doubled penalty.
A person can use the substance only on private property. Public consumption is punishable by a fine of up to $100.
Patients with certain debilitating medical conditions and their primary designated caregivers are also allowed to have up to 2 oz of usable marijuana.
However, home cultivation remains illegal under the current law.
