Legislative History

Maryland voters approved Question 4 — a constitutional amendment authorizing adult-use cannabis — on November 8, 2022, with 67% in favor. This was one of the largest approval margins for any state cannabis legalization ballot measure. The constitutional amendment authorized the General Assembly to pass implementing legislation establishing the regulatory and commercial framework.

Governor Wes Moore signed the Cannabis Reform Act on May 3, 2023. Recreational retail sales launched on July 1, 2023, as existing medical dispensaries converted to dual-use operations. The Maryland Cannabis Administration (MCA) was created as the independent state agency responsible for licensing, inspections, consumer protection, and social equity program administration for both adult-use and medical cannabis.

Maryland’s proximity to Washington DC gave the July 2023 retail launch particular regional significance. DC has a unique cannabis framework where adult possession is legal but commercial sales are restricted due to a congressional rider blocking regulated retail. Maryland became the immediate alternative for DC residents and visitors seeking regulated cannabis retail access. Baltimore City and the DC suburbs (Montgomery County, Prince George’s County) became the state’s highest-volume cannabis markets.

Possession Limits in Detail

Maryland’s tiered approach to possession distinguishes between legal amounts, a civil-fine zone, and criminal thresholds — a nuanced framework reflecting the state’s broader decriminalization philosophy embedded in the Question 4 framework:

Amount (Flower Equivalent)	Location	Legal Consequence
Up to 1.5 oz (42 g)	Public	Fully legal; no penalty
1.5 oz to 2.5 oz	Public	Civil fine up to $250; no criminal record
Up to 2.5 oz	Private residence	Fully legal; no penalty
Over 2.5 oz	Any location	Criminal misdemeanor; potential fines and jail
Per dispensary transaction	Licensed retail	1.5 oz flower equivalent
Medical patients	Any	Higher limits per patient certification

Home Cultivation Rules

Home cultivation in Maryland became legal on July 1, 2023, the same date as retail sales:

Rule	Detail
Plants per adult	2
Household maximum	4 plants (2 adults maximum benefit)
Plant stages	No separate mature/immature distinction stated
Visibility restriction	Not visible from public place or road
Security requirement	Inaccessible to minors; secured space
Home-grown harvest storage	Must remain within 2.5 oz home limit
State registration required	No registration required for personal grows

Maryland’s 2-plant-per-adult limit is one of the more restrictive among legal states. For context, New Mexico allows 6 per adult and Michigan allows 12 plants per adult. The conservative home grow allowance reflects legislative compromise between cannabis advocates and more cautious legislators during the Cannabis Reform Act negotiations.

Dispensary and Purchase Rules

Licensed dispensaries must verify age at every transaction with valid government-issued photo ID. Acceptable identification includes US driver’s licenses, passports, military IDs, and foreign passports. No residency requirement applies; out-of-state visitors and DC residents may purchase freely.

Baltimore City has the highest concentration of licensed dispensaries in the state. Montgomery County and Prince George’s County — both DC suburbs with large populations — have significant retail activity. The Eastern Shore and western Maryland counties have fewer dispensaries. Cannabis delivery is permitted for licensed retailers; delivery availability varies by operator. All cannabis purchased in Maryland must remain in Maryland; crossing into DC or Virginia carries federal legal risk.

Tax Structure

Tax Component	Rate	Notes
State cannabis excise tax	9%	Cannabis-specific retail excise
Maryland sales tax	6%	Standard rate applies to recreational cannabis
Combined effective rate	~15%	Before any additional local county additions
Medical cannabis excise	9%	Same excise rate applies
Medical cannabis sales tax	0%	Standard 6% sales tax exempt for medical
Effective medical rate	~9%	Significant savings for registered patients

The tax differential between recreational (~15%) and medical (~9%) creates an incentive for regular cannabis users to obtain a Maryland medical card. Medical certification costs approximately $75–200 per year including the physician consultation, plus the state registration fee. For a consumer spending $150 per month on cannabis, the tax savings from the lower medical rate amount to approximately $108 per year.

Driving Under the Influence of Cannabis

Driving under the influence of cannabis is a criminal offense in Maryland under Transportation Article Section 21-902. Maryland does not have a per se THC blood-level threshold. Law enforcement relies on observed impairment, standardized field sobriety testing, and Drug Recognition Evaluator assessments. A first DUI conviction in Maryland carries mandatory fines, license suspension, and potential jail time. Cannabis must be in a sealed container away from the driver’s reach while in a vehicle. Open container violations for cannabis carry separate civil penalties.

Employment and Housing Rights

Maryland does not broadly prohibit employer cannabis testing. Employers may maintain drug-free workplace policies and test for cannabis through pre-employment, random, reasonable-suspicion, and for-cause testing programs. The Cannabis Reform Act does not require employers to accommodate lawful off-duty cannabis use or disregard positive drug test results in employment decisions. Safety-sensitive and federally regulated roles retain full testing rights.

Landlords may prohibit cannabis smoking and cultivation in rental properties. Federally subsidized housing applies federal cannabis prohibitions. Workers’ compensation coverage may be affected when cannabis impairment is found to have contributed to a workplace injury documented under the employer’s drug-free workplace policy.

Expungement of Prior Convictions

Maryland’s Cannabis Reform Act included automatic expungement provisions for prior cannabis possession charges involving amounts now legal under the law. Eligible charges from before November 2022 — when Question 4 passed — are expunged automatically by the courts without requiring individual petitions. This covers the largest category of historical cannabis arrests in Maryland: simple possession of small amounts.

More serious prior convictions for distribution, possession with intent to distribute, or amounts substantially exceeding personal-use thresholds are not automatically expunged. Individuals with such convictions may petition the court where the conviction was entered. The MCA maintains a social equity licensing framework that specifically includes individuals with cannabis conviction history as qualifying equity applicants, creating pathways into the legal industry.

Social Equity Provisions

Maryland’s Cannabis Reform Act established two dedicated funds supported by cannabis tax revenue: the Social Equity Fund and the Cannabis Business Assistance Fund. The Social Equity Fund provides grants, low-interest loans, and technical assistance to equity applicants. The Reinvestment Fund directs a portion of cannabis taxes toward communities most affected by historical cannabis enforcement.

Baltimore City and Prince George’s County are designated priority communities for equity licensing allocation, reflecting their histories as Maryland’s highest-enforcement jurisdictions. Equity applicants receive priority licensing review, reduced fees, and dedicated access to the Social Equity Fund. The MCA also maintains a Social Equity Consultation and Assessment program to assist applicants through the licensing process.

Local Jurisdiction Rules

Maryland counties and municipalities may impose zoning restrictions on cannabis retail locations, including setback requirements from schools, parks, residential zones, and houses of worship. Local governments may also regulate operational hours. However, they may not impose outright bans on licensed cannabis businesses under the Cannabis Reform Act framework. Baltimore City, Montgomery County, and Prince George’s County have the most active regulatory frameworks for cannabis retail; some smaller rural counties have used aggressive zoning to limit retail density.

Medical Cannabis Program

Maryland’s General Assembly authorized medical cannabis in 2014; the program launched operationally in 2017. Qualifying conditions include severe or chronic pain, PTSD, anorexia, cachexia, severe nausea, seizures, severe muscle spasms, multiple sclerosis, ALS, and other serious or chronic conditions where conventional treatment is ineffective and cannabis is likely to provide therapeutic benefit per a licensed provider’s written certification. Patients register with the MCA and obtain an ID card. Medical patients benefit from the lower ~9% effective tax rate and higher possession and purchase limits than recreational consumers.

DC Proximity and Federal Enclave Rules

Washington DC operates under a unique framework where adult possession of cannabis is legal but commercial sales are effectively prohibited due to a congressional budget rider that blocks the DC government from regulating cannabis sales. DC residents and visitors have historically used informal “gifting” markets to access cannabis. Maryland’s legalized retail provides DC-area consumers with their closest regulated cannabis market.

However, the Maryland-DC border is a federal jurisdictional boundary. Bringing cannabis across it — in either direction — is a federal offense regardless of both jurisdictions’ local laws. The Chesapeake and Ohio Canal National Historical Park and other federal properties along the Maryland-DC border enforce federal drug law. Cannabis consumed in Maryland must be purchased in Maryland and consumed on Maryland private property.

Interstate Transportation Rules

Maryland borders DC, Virginia, West Virginia, Pennsylvania, and Delaware. Virginia has legal adult-use cannabis but complex implementation; Delaware also has adult-use sales; Pennsylvania does not yet have adult-use cannabis. Transporting cannabis across any of Maryland’s borders is a federal offense regardless of the neighboring state’s laws. I-95, I-270, I-83, and Route 50 all cross state or DC boundaries and are subject to federal jurisdiction at those crossings.

Frequently Asked Questions

Can I use Maryland cannabis while visiting from Washington DC?

You may purchase at a licensed Maryland dispensary; no residency requirement applies. You must consume within Maryland on private property. Bringing cannabis across the Maryland-DC border is a federal offense because DC is a federal enclave. Federal law governs the Maryland-DC boundary regardless of either jurisdiction’s local cannabis policies.

Are there cannabis consumption lounges in Maryland?

The MCA has been developing social consumption venue rules. As of May 2026, on-site consumption at retail locations is not broadly available in Maryland. Check the MCA website for current licensed consumption venue status in Baltimore and other major markets.

Does Maryland allow cannabis delivery?

Licensed retailers may offer delivery to private residences in Maryland. Drivers must verify ID at the point of delivery. Delivery availability depends on individual retailer licenses and local policies. Coverage is strongest in the Baltimore metro area and DC suburbs.

What ID do I need to buy cannabis in Maryland?

A valid government-issued photo ID demonstrating age 21 or older is required at every dispensary visit. Acceptable forms include US driver’s licenses, passports, military IDs, and foreign passports with a photo and date of birth. Dispensaries may not sell to anyone unable to provide valid age-verifying identification.

How does the social equity licensing work in Baltimore City?

Baltimore City is a designated priority community for Maryland’s social equity cannabis licensing. Equity applicants who meet income, residency, or cannabis conviction history criteria receive priority processing and fee reductions. The MCA’s Social Equity Fund provides grants and loans to certified equity applicants in Baltimore and other priority communities. The Reinvestment Fund additionally directs tax revenue back to these communities for social services and economic development programs.
