Cannabis edibles are legal in Maryland for adults 21 and older and for registered medical cannabis patients, as long as the products are bought from a dispensary licensed by the Maryland Cannabis Administration. Adult-use sales of gummies, chocolates, tinctures, lozenges, and other THC-infused products started on July 1, 2023, under the Cannabis Reform Act signed by Governor Moore earlier that spring.1Maryland Cannabis Administration. MCA Timeline The rest of the answer is in the limits: how much THC a product can contain, how much you can carry, where you can eat it, and what still runs you into trouble.
Who Can Buy, and Where
Only two groups can legally purchase edibles in Maryland: adults 21 or older, and medical cannabis patients, who can be as young as 18 with a valid registration. Both must buy from a dispensary licensed by the MCA. No gas station, smoke shop, or online seller is an authorized retail channel for THC edibles.
Adult-use customers need a government-issued photo ID at the counter proving they are at least 21. A driver’s license, state ID, passport, military ID, or tribal card all work. Medical patients need a written certification from a registered physician and a patient ID card issued through the state program.2Maryland General Assembly. House Bill 881 Chapter 240 – Medical Cannabis
Expect a 9% sales and use tax on recreational purchases, the same rate Maryland charges on alcohol.3Maryland Comptroller. Adult Use Cannabis Information Medical patients do not pay that tax.
Potency Caps
Maryland caps the THC in each edible, and the cap depends on which program you are buying through.
Adult-use edibles are limited to 10 milligrams of THC per serving and 100 milligrams per package.4Library of Maryland Regulations. COMAR 14.17.13.05 – Edible Cannabis Products A typical gummy pack holds ten 10-milligram pieces.
Medical edibles can go up to 40 milligrams per serving and 400 milligrams per package. That is four times the recreational ceiling, which is one reason some patients keep their certification active even after legalization.
How Much You Can Possess
Possession limits for edibles are measured by total delta-9-THC, not by the weight of the brownie or gummy itself. An adult-use consumer can hold edibles containing up to 750 milligrams of THC.5Maryland Cannabis Administration. MCA Guide Adult Use 21+ That works out to roughly seven or eight full 100-milligram packages. The personal-use rules also allow up to 1.5 ounces of flower and 12 grams of concentrate, but those are counted separately from the edible total.
Medical patients get a possession ceiling set by their certifying physician, which can run higher than the recreational limits depending on their treatment plan.
Penalties for Going Over
Carrying edibles with between 750 and 1,250 milligrams of THC is a civil offense with a fine of up to $250. Above 1,250 milligrams of THC in edibles is a criminal misdemeanor under Maryland Criminal Law §§ 5-601 and 5-601.1, which carries potential jail time on top of a fine.
Where You Can Eat Them
Legal to buy does not mean legal everywhere. The safe place to consume an edible is private property where the owner allows it. Landlords, HOAs, and employers can all prohibit cannabis use on their premises regardless of state law.
Consuming cannabis in a public place is a civil offense: up to $50 for a first violation and up to $150 for repeats. Public place is read broadly, covering parks, sidewalks, restaurants, bars, and the common areas of apartment buildings. Local jurisdictions can tack on their own restrictions.
Driving After an Edible
Driving under the influence of cannabis is illegal in Maryland under Transportation § 21-903, and edibles are a particular hazard because the high arrives late. Most people start feeling an edible between 30 minutes and two hours after eating it, and the effects can last several hours. The familiar trap is eating a gummy, feeling nothing after 45 minutes, driving somewhere, and becoming impaired on the way.
Maryland has no per-se THC blood level that automatically produces a DUI the way 0.08% blood alcohol does. Officers rely on observation and field sobriety testing instead. Research from the National Institute of Justice has found that standard field sobriety tests, which were designed around alcohol, are not reliable indicators of cannabis intoxication.6National Institute of Justice. Field Sobriety Tests and THC Levels Unreliable Indicators of Marijuana Intoxication That cuts both ways in court, and it does not stop an arrest from happening. The practical rule is to leave several hours between an edible and the driver’s seat.
Making Your Own at Home
Since July 1, 2023, Maryland adults can grow up to two cannabis plants at home for personal use. The two-plant cap applies per residence, not per person, so a household with several adults still shares the same two-plant limit. Registered medical patients can grow up to four plants per residence. Homegrown cannabis can go into edibles you make for yourself, but homemade edibles cannot be sold. Only licensed processors and dispensaries can sell cannabis edibles in Maryland.
Packaging You Can Trust
Legal Maryland edibles come in child-resistant, tamper-evident packaging and carry labels showing total THC, THC per serving, ingredients, and health warnings about delayed onset.7New York Codes, Rules and Regulations. Maryland Code Alcoholic Beverages and Cannabis 36-203.1 – Potency, Labeling and Packaging Cartoon imagery or packaging that mimics commercial candy is not allowed. If an edible you come across lacks any of this, it almost certainly did not come through the licensed supply chain, and buying it means forfeiting the legal protections above.
The Federal Catch
Everything above is Maryland law. Under federal law, cannabis is still a Schedule I controlled substance.8Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances For a Maryland consumer, the two places that conflict matters most are travel and the mail.
Carrying Maryland-legal edibles across state lines is a federal crime, even when the destination state has also legalized cannabis. The TSA is not actively looking for cannabis, but if screeners find THC products they are required to refer the matter to law enforcement.9Transportation Security Administration. Medical Marijuana Hemp-derived products with no more than 0.3% THC by dry weight are the only exception, and standard dispensary edibles are nowhere near that threshold. The FDA separately treats introducing THC-containing food into interstate commerce as a prohibited act,10U.S. Food and Drug Administration. FDA Regulation of Cannabis and Cannabis-Derived Products Including Cannabidiol which is why Maryland’s edible market stays inside the state. Keep what you buy in Maryland in Maryland.
