Public consumption remains illegal in Washington, DC. The Metropolitan Police Department makes clear on its website that consuming marijuana in any form–or even holding or carrying a lighted roll of paper or other lighted smoking equipment filled with marijuana – in any public space is illegal.
District code dictates that public consumption remains a crime, punishable by up to 60 days in jail and a fine of up to $500.
Technically, because some portions of Washington, DC are federal land, penalties may vary.
In practice, public consumption will result in a $25 fine. Alternatively, offenders may choose to go to court per 2018 policy recommendations issued by the mayor’s office.
