Whether you're a resident of Washington D.C. or you're visiting the DMV as a tourist, you may be wondering how old you have to be to smoke weed in America's capital district. Residents of Washington D.C. voted in favor of passing the Legalization of Possession of Minimal Amounts of Marijuana for Personal Use Initiative (Initiative 71) in November of 2014 to allow adults who are at least 21 years of age to consume cannabis at their leisure.

Since February 26, 2015, anyone at least 21 years old has been able to smoke weed legally in Washington D.C., but Congressional rules prohibit the sale and taxation of cannabis within the borders of the District of Columbia, so you must either grow your own or receive some green as a gift, as there are no plans for allowing dispensaries to open like in Colorado.

The rule of thumb in Washington D.C. is “home grow, home use,” and adults who are at least 21 old can have no more than two ounces of cannabis in their possession for personal use. They can grow up to six plants at his or her primary residence, but no more than three plants can be mature at one time. Washington D.C. allows individuals to “transfer” up to one ounce of cannabis to another adult at least 21 years of age, as long as nothing of value is given as payment.

Also, just because you're 21 years old doesn't mean you can smoke weed anywhere you please in the capital. D.C. restricts cannabis use to private property and prohibits its public consumption, and (just like other states where cannabis is legal) you're not allowed to smoke weed while (or right before) driving a car, boat, or other motorized vehicle, or even while you're sitting in one while it's stopped. It's also important to remember that you can't transport cannabis across the borders of the District and take it into one of the neighboring states.

In ending, you can learn more about the regulations regarding cannabis consumption in Washington D.C. by checking with the Metropolitan Police Department; until then, enjoy smoking weed in the in the nation's capital!
