Is Marijuana Legal in Maryland, DC, and Virginia?

Marijuana is legal for adults 21 and older in Maryland, Washington, D.C., and Virginia, but the three sit at very different points on the same road. Maryland has licensed recreational stores open. D.C. allows possession and home growing but has no legal recreational retail. Virginia allows possession and home cultivation, and stores are not expected to open until January 2027 at the earliest. What you can legally do with cannabis changes the moment you cross a border in this region, and federal property scattered throughout adds a layer of risk that local legalization does not touch.

Maryland Rules for Possession, Growing, and Buying

Maryland voters approved a ballot referendum in November 2022, and Governor Moore signed the Cannabis Reform Act on May 3, 2023.¹ Adults 21 and older may possess up to 1.5 ounces of cannabis flower or 12 grams of concentrate. Between the personal-use amount and 2.5 ounces is a civil offense with a fine of up to $100. Larger quantities can bring misdemeanor charges carrying up to six months in jail or a $1,000 fine.

Home cultivation is capped at two plants per household, no matter how many adults live there. Plants cannot be visible from a public area or a neighboring property without binoculars or other optical aids, and growers must keep them in an enclosed, locked space away from anyone under 21. Breaking the cultivation rules is a misdemeanor punishable by up to three years in prison or a $5,000 fine.²

Retail sales launched on July 1, 2023, through existing medical dispensaries that converted to dual-use licenses.³ Adult-use purchases carry a 9% sales and use tax, the same rate Maryland applies to alcohol.¹ Dispensaries verify ID at every transaction, and the Maryland Cannabis Administration handles licensing and enforcement.

D.C. Rules and Why There Are No Recreational Stores

D.C. voters approved Initiative 71 in November 2014. Adults 21 and older may possess up to two ounces of marijuana. Adults may also transfer up to one ounce to another adult at no cost, meaning no money, goods, or services can change hands.⁴

Home cultivation is more generous than in the neighboring states. A single adult can grow up to six plants, with no more than three mature and flowering at once. In a household with multiple adults, the cap rises to 12 total plants, with a maximum of six mature. Every plant must be inside the grower’s principal residence. Selling any cannabis or cannabis plants, including homegrown, is illegal under the same statute.

Despite legalizing possession more than a decade ago, D.C. has no licensed recreational dispensaries. A congressional appropriations rider first attached in 2015, commonly called the Harris Rider, blocks the District from spending local tax revenue to create a commercial adult-use market. Congress has renewed it every year since, and it remained in place through at least fiscal year 2025. Until Congress drops or modifies the rider, D.C. cannot license or regulate recreational retail sales.

That gap produced a “gifting” economy, where businesses nominally sell a sticker or T-shirt and include cannabis as a free gift. D.C.’s Alcoholic Beverage and Cannabis Administration has been closing unlicensed operators and confiscating product. The only legal way to buy cannabis in D.C. is through a licensed medical dispensary with a valid patient registration.

Out-of-state medical patients can apply for a temporary non-resident registration card through the Alcoholic Beverage and Cannabis Administration.⁵ You need a valid, government-issued medical cannabis card from your home state, plus a government-issued ID. Cards from private organizations do not qualify. Maryland and Virginia medical cardholders are eligible.

Virginia Rules and the Coming Retail Market

Virginia legalized possession for adults 21 and older in 2021. You may carry up to one ounce of marijuana in public.⁶ Penalties escalate above that threshold:

More than 1 ounce up to 4 ounces: a civil penalty of up to $25.
More than 4 ounces up to 1 pound: a Class 3 misdemeanor for a first offense, Class 2 misdemeanor for a second or subsequent offense.
More than 1 pound: a felony carrying one to ten years in prison and a fine of up to $250,000.

Those tiers apply to public possession. Virginia does not cap how much cannabis you can keep inside your own home, but you still cannot sell it.

Home cultivation is limited to four plants per household regardless of how many adults live there. Every plant must carry a legible tag showing the grower’s name, driver’s license or ID number, and a note that the plant is for personal use. Plants must be invisible from any public way and secured against access by anyone under 21. Exceeding four plants brings a $250 civil penalty for five to ten plants on a first offense, a Class 1 misdemeanor for 11 to 49 plants, and a felony for 50 or more.⁷

When Virginia legalized possession in 2021, the retail sales provisions were subject to a reenactment clause the legislature never passed, leaving no legal way to buy cannabis. That changed in March 2026, when the General Assembly passed HB 642 / SB 542, establishing a framework for licensed adult-use retail.⁸ The Cannabis Control Authority is expected to begin accepting retail license applications in September 2026, and the earliest any store can open is January 1, 2027. Until then, Virginians can only obtain cannabis through home cultivation or private, no-cost transfers between adults.

Age Limits and Where You Can Actually Use It

All three jurisdictions set the legal age at 21 for possession, cultivation, and use.³⁹ Providing cannabis to anyone under 21 is a criminal offense throughout the region.

Public consumption is banned everywhere, but penalties differ. In Virginia, consuming cannabis in a public place carries a civil penalty of up to $25 for a first offense. A second offense adds a mandatory referral to a substance abuse program, and a third or subsequent offense becomes a Class 4 misdemeanor.¹⁰ In Maryland, smoking cannabis in a public place is a civil offense with fines starting at $50 and rising to $150 for later violations. D.C. treats public consumption more seriously: it is a misdemeanor punishable by up to 60 days in jail or a fine.¹¹ D.C.’s definition of “public place” is broad and includes clubs, bars, and parking areas.

The practical rule everywhere in the region is that legal consumption happens inside a private residence with the owner’s permission. Using cannabis inside a vehicle is illegal for both drivers and passengers throughout the three jurisdictions.

Driving After Using Cannabis

All three jurisdictions treat impaired driving as a serious criminal offense. None uses a per se THC blood limit equivalent to the 0.08% threshold for alcohol. Prosecutors rely on evidence of observable impairment, officer testimony, and drug recognition experts.

In Virginia, a first-offense cannabis DUI can bring up to one year in jail, fines up to $2,500 with a mandatory minimum of $250, and loss of your driver’s license for up to a year.¹² In Maryland, driving impaired by any drug falls under the same DUI statute as alcohol. D.C. imposes up to 180 days in jail and a $1,000 fine for a first offense, with an additional mandatory minimum of 15 days if a drug test shows a Schedule I substance in the driver’s system.

Federal Property Is a Different Country

Marijuana remains a Schedule I controlled substance under federal law, and the DEA still classifies it alongside heroin and LSD.¹³ That classification matters in a region packed with federal land. The National Mall, Rock Creek Park, Arlington National Cemetery, every federal building, and any property managed by the National Park Service fall under federal jurisdiction. Local police have no authority there; federal officers do.

A first offense for simple possession on federal property can bring up to one year in prison and a mandatory minimum fine of $1,000.¹⁴ The penalty climbs with prior convictions. These are not theoretical risks for tourists on the Mall with a vape pen or commuters cutting through a federal park.

Crossing the Border With Cannabis

Even though Maryland, D.C., and Virginia all allow adult possession, moving cannabis across any border between them technically triggers federal jurisdiction. Transporting marijuana across state lines violates 21 U.S.C. § 841 regardless of the legality on either side.¹⁵ For amounts under 50 kilograms, a first offense can mean up to five years in federal prison and a $250,000 fine.

Federal authorities rarely target individuals carrying personal-use amounts between neighboring jurisdictions, but the risk is real and it becomes acute in specific situations: crossing the Potomac River bridges, driving through the District on I-95 or I-66, or carrying cannabis through Reagan National or Dulles, both of which sit on federal land governed by federal law. Air travel with cannabis is illegal under federal law, and TSA agents are required to report any marijuana they discover to law enforcement.

What Your Employer Can Still Do

Legalization does not mean your employer has to be fine with it, and workplace protections vary sharply.

D.C. offers the strongest employee protections. Under the Cannabis Employment Protections Amendment Act of 2022, employers cannot refuse to hire, fire, suspend, or demote someone based solely on their cannabis use or the presence of THC metabolites in a drug test.¹⁶ Employers can still act if the employee is actually impaired on the job, meaning specific observable symptoms that substantially decrease work performance. Safety-sensitive positions, including security officers, heavy equipment operators, and healthcare workers handling patients, are exempt. Employers governed by federal contracts or regulations can still enforce zero-tolerance policies.

Maryland’s legalization law signaled that employers should exercise caution with cannabis-related drug test results, but the state has not enacted the same explicit statutory shield D.C. has. Virginia’s cannabis laws do not address employment protections at all. In both states, most private employers retain broad discretion to test for cannabis and make hiring or firing decisions based on the results. Federal employers and contractors can enforce drug-free workplace requirements everywhere in the region regardless of local law.

The Three Jurisdictions at a Glance

Maryland: possession up to 1.5 oz legal; two plants per household; retail stores open since July 2023; 9% sales tax; public consumption fine starts at $50.
Washington, D.C.: possession up to 2 oz legal; six plants per adult with three mature; no recreational retail because of the congressional rider; gifting up to 1 oz allowed; public consumption is a misdemeanor.⁴
Virginia: possession up to 1 oz in public legal; four tagged plants per household; no retail sales until at least January 2027; public consumption fine is $25.

All three require you to be 21, ban public consumption, and offer no protection on federal land. The gap between what you can possess and what you can buy will likely keep narrowing in Virginia and D.C. over the next few years.
