Medical cannabis is legal in Maryland, and medical dispensaries have been operational since December of 2017. The state has not legalized recreational (adult-use) cannabis. 

Medical marijuana was initially legalized under two laws in 2013, House Bill 180 and House Bill 1101. However, these two pieces of legislation alone were insufficient to establish a state-wide medical marijuana program. The needed legislation would come in 2014 in the form of House Bill 881, which established the Maryland Medical Cannabis Commission to oversee the state's medical market.


In Maryland, possession is based on a 30-day supply. The state imposes a cap of 120 grams (about four ounces) for possession at any time unless a patient receives a special determination from a physician stating that a 120 gram 30-day supply is an inadequate treatment.

Similarly, patients are limited to 36 grams of THC extract per month.

Purchasing Limits

Maryland does not state any purchasing limits for how much a patient may purchase during a single visit to a dispensary. However, patients and caregivers should refer to the allowances for possession to determine the max amount of cannabis they are allowed to purchase per 30 days. Where to Buy


Approved patients can consume cannabis via smoking, vaporizers, extracts, topicals, tinctures and as add-ons to food, though edibles are not sold in Maryland dispensaries. Additionally, patients cannot possess or consume their cannabis on any federal property in the state.

Regulations require patients to sign a statement affirming they understand that they are not immune from any prohibition on smoking cannabis in a public place or in a motor vehicle, or on private property where it is prohibited by the property owner.

Qualifying Patients

Maryland's Medical Cannabis Law (pdf) allows the following medical conditions to qualify for its program:

  • Anorexia
  • Cachexia
  • Chronic or Severe pain
  • Glaucoma
  • Persistent muscle spasms
  • PTSD
  • Seizures
  • Severe nausea

Additionally, physicians have the ability to recommend cannabis for any another chronic medical condition which is severe and for which other treatments have been ineffective. Get Your Card

Driving Under the Influence

Driving under the influence of medical marijuana in Maryland is illegal. Patients are not exempt from civil, criminal or any other penalties and could face similar charges enforced in alcohol DUI cases.

Transporting Marijuana

The state allows legal medical marijuana patients to travel anywhere in the state with their medicine, except for federal property. Maryland’s Medical Cannabis Commission emphasizes that all patients be aware of current laws around the transporting of medical marijuana outside of the state, as it remains a federal offense.

Exporting Marijuana

Due to existing federal regulations,  Maryland does not authorize the exporting of medicinal marijuana outside of Maryland’s borders. People who transport cannabis across state lines may face steep penalties.


Only state-approved growers are permitted to cultivate medical marijuana in Maryland. Home cultivation is not permitted.


Maryland allows medical cannabis delivery. 


Maryland does not offer reciprocity to out-of-state cardholders.
