Smoking cannabis (and hemp) is prohibited in any public place. This includes outdoor spaces and indoor spaces open to the public including parks, streets and sidewalks, bars and restaurants, public transportation (e.g, buses, vans, trains, taxicabs, limousines) and indoor places of employment. Because cannabis remains illegal at the federal level, you also may not possess cannabis on any federal property such as national park.
Using cannabis while driving (by a driver or passenger) and impaired driving remains illegal under Maryland law. Law enforcement officers can make a cannabis DUI arrest if they observe impairment using a standard field sobriety testing (roadside test) method. Let’s keep Maryland safe and plan ahead before using cannabis. Learn more with this Cannabis and Driving Don’t Mix fact sheet.
Cannabis can impair important skills needed for safe driving. These include coordination, judgement, and reaction time – remember, reacting too slowly can be just as dangerous when driving. Because it may not be easy to recognize when you are impaired by cannabis, and effects from cannabis edibles can be delayed, be responsible and always make a plan before consuming. Learn more with this Cannabis and Driving Don’t Mix fact sheet.
Like tobacco and alcohol, the legal purchase age for cannabis in Maryland is 21 or older. Valid, government-ID (driver’s license, passport) is required at the point-of-sale. Licensed dispensaries are the only place to legally buy cannabis in Maryland.
No. Cannabis remains illegal under federal law, and you may not carry or transport cannabis over state lines. It remains illegal to leave (or enter) Maryland with any cannabis products – medical or adult-use (non-medical) products. Mailing cannabis in or out of the State is illegal.
Cannabis products may be purchased from licensed dispensaries. Cannabis products are subject to a 9 % sales tax (the same as alcohol).
A person may purchase cannabis or cannabis products from a licensed dispensary if they display a government-issued photo ID at the point-of-sale that demonstrates they are 21 years or older (driver’s license, state ID card, passport/passport card, military ID, tribal card). Individuals will only be able to purchase up to the personal use amount authorized under law. This amount is up to 1.5 ounces of cannabis flower (including joints and pre-rolls), 12 grams of concentrated cannabis (vape products), or a total amount of edible cannabis products that does not exceed 750 mg THC.
Maryland voters approved a ballot referendum in the 2022 General Election to allow use of cannabis by adults 21+ (hence, “adult-use”) starting July 1, 2023. During the 2023 legislative session, the General Assembly passed legislation that provided a framework for implementing legal adult-use sales, including a licensing and taxation framework (see House Bill 556/Senate 516). The Cannabis Reform Act, which took effect immediately upon Governor’s signature on May 3, 2023, authorized existing licensed dispensaries to convert their licenses for dual medical and adult-use sales by July 1, thereby creating a legal adult-use marketplace as of July 1, 2023. The Act also authorized the Maryland Cannabis Administration to issue additional grower, processor, and dispensary licenses, and new incubator licenses over two licensing rounds.
The legislation prioritizes equity in cannabis licensing and seeks to ensure that individuals and communities harmed by cannabis prohibition can access the economic opportunities associated with cannabis legalization. Specifically, it prioritizes diversity and equity in licensing by:
Yes, the use and possession of cannabis remains illegal under the Federal Controlled Substances Act of 1970 (CSA). States may allow adult use within their jurisdictions, but interstate transport is still prohibited under federal law. Cannabis possession also remains
unlawful on federal land (including federal buildings, national parks, military bases, etc.), even within states that have legalized it.
As of July 1, 2023, any product containing more than 0.5 mg THC per serving and 2.5 mg THC per package, with the exception of certain full spectrum tincture products, may only be sold in a licensed cannabis dispensary. This requirement extends to all THC isomers, including delta-8, delta-9, and delta-10.
Effective July 1, 2023, a person 21 years or older may lawfully possess and use cannabis.
A medical card is still needed to purchase cannabis sold as part of the medical cannabis program. Learn more about the Medical Cannabis Program here.
Only individuals who are registered, certified Maryland medical cannabis patients and caregivers can purchase products under the parameters of Maryland’s Medical Cannabis Program. However, individuals from out-of-state who are at least 21 years of age with government-issued ID will be permitted to purchase adult-use cannabis from licensed dispensaries in Maryland beginning July 1, 2023. Interstate transport of cannabis is still prohibited under federal law.
No, members of the military are not exempt. Only persons aged 21 years or older may use or possess non-medical cannabis. Other federal restrictions on the use or possession of cannabis may apply to members of the military.
Adults 21 years and older may possess up to 1.5 ounces of cannabis flower, up to 12 grams of concentrated cannabis; or a total amount of cannabis products that does not exceed 750 mg of THC. This is known as the “personal use amount.”
A person under 21 years of age may not possess or use non-medical cannabis. Possession of 2.5 ounces or less (a civil use amount) may result in a fine, a court order to attend drug education programming, and referral for assessment and/or treatment of substance use disorder. Possession of more than 2.5 ounces may result in criminal penalties.
A person 21 years or older may lawfully cultivate up to two plants in their home, out of public view. Likewise, a household may cultivate a maximum of two plants, regardless of how many persons over age 21 live in the residence. Individuals under 21 are not permitted to cultivate cannabis plants. In addition, medical patients registered with the Maryland Cannabis Administration can cultivate two additional plants, for a total of four plants; not to exceed more than four plants in a given residence. Landlords and property owners can prohibit growing cannabis on their properties.
Adults 21+ can use cannabis in private homes and private property. However, landlords and management companies can prohibit cannabis use. If you rent, be sure to read your rental agreement. Most hotels do not permit guests to smoke cannabis in their rooms. Ask the hotel reception desk about their policy. If you stay in a vacation rental, check with the property owner about their rules for your stay.
The Cannabis Reform Act does not address cannabis use or impairment in the workplace. Individuals remain subject to any existing laws and workplace policies on substance or cannabis use (e.g., federal laws prohibiting the operation of commercial transport vehicles while impaired, or workplace policies prohibiting cannabis use specifically and/or impairment generally). The legislation does not address the use of employer drug screening of employees or prospective employees. Your employer or prospective employer can provide more specific information about its policies regarding substance use in the workplace.
In addition to prohibiting cannabis use and possession for individuals under 21 years of age, the Cannabis Reform Act includes public health best practices to prevent youth access and to reduce the appeal of cannabis to youth. These include marketing and advertising restrictions, age verifications at the point of sale, child-resistant packaging, and restrictions on sales near schools and youth-serving locations like libraries and parks.
Cannabis use can harm the health and wellbeing of youth and young adults. Cannabis use may permanently affect the developing brain, especially with regular or heavy use.2 Parents, caregivers, and trusted adults should discourage youth and young adults from using cannabis; should not consume cannabis in front of youth or young adults; and should always keep cannabis out of sight and locked if it is stored in the home. See Storing Cannabis Safely fact sheet.
The health impacts of cannabis use are not fully known. Studies have linked cannabis use, especially frequent use with cannabis use disorder and addiction, anxiety and paranoia,9 and psychosis 10. People who smoke or vape cannabis regularly, even without tobacco, are more likely to experience irritation or inflammation in the lining of the lungs. 11,12,13 Secondhand cannabis smoke may also pose health risks as it has been found to contain many of the same toxic and cancer-causing chemicals in tobacco smoke.14
A product being legal does not mean it is safe for anyone to use. Much is unknown about the short and long-term effects of cannabis use during pregnancy and while breastfeeding. The American College of Obstetrics and Gynecologists and the American Academy of Pediatrics recommend NOT using any type of cannabis (including CBD) while pregnant or breastfeeding. See Cannabis and Pregnancy & Breastfeeding fact sheet.
Using alcohol and cannabis at the same time can result in greater impairment than when using either one alone, which can lead to greater risk for personal harm (and harm to others).15 Tobacco and cannabis used together increases your exposure to chemicals that may harm the lungs and cardiovascular system (heart and blood vessels).16 Cannabis may alter the effects and/or potency of prescription medication.17 Always talk with your doctor about any medications you are taking or thinking about taking and the possible side effects when mixed with other substances including cannabis.
Cannabis is a plant with many names- marijuana, weed, pot, cannabis, hash- that can have psychoactive characteristics and is consumed for medical and non-medical (recreational) purposes. The cannabis plant has hundreds of chemical compounds, including cannabinoids and terpenes.
No. The new legislation replaces references to marijuana with “cannabis” in the Maryland Code. Either term refers to flowering plants in the genus Cannabis.
The cannabis plant produces more than 100 different cannabinoids, which are compounds that can have different effects on the mind and body. Tetrahydrocannabinol known as “THC” and cannabidiol known as “CBD” are the most common. THC is known for its psychoactive effects (a feeling of being high). There are different forms of THC, including delta-9-THC, traditionally found in most cannabis products. However, other forms of THC, such as delta-8-THC and delta-10-THC can also be found in cannabis plants and will be included in the regulated market as part of this legislation.
CBD, or cannabidiol, is the second most prevalent cannabinoid in cannabis. Unlike THC, CBD does not cause a “high” or psychoactive effect by itself.
Hemp refers to varieties of cannabis plants that contain 0.3% or less delta-9-THC. The hemp plant has various industrial uses, as well as can be made into consumable products derived from hemp. The new adult-use legislation regulates consumable and inhalable intoxicating hemp products with other cannabis products, while exempting non-intoxicating products, such as CBD edibles, lotions, and tinctures.
