Marijuana Regulations in Maryland

Cannabis use is only for certified patients. All content is intended for viewers 18 or older.

All registered qualifying patients must notify the MMCC:

  • Of changes in the patient’s name or address
  • If the registry identification card is damaged, lost or stolen
  • If the patient changes caregivers (patients cannot have more than two caregivers)  
  • A registered qualifying patient must carry his or her registration card at all times while in possession of cannabis
  • A caregiver must carry his or her caregiver identification card at all times while in possession of cannabis

Safely and Legally Storing Medical Cannabis

Patients are responsible for keeping their medical cannabis fully safe and secure. Medical cannabis can be an attractant to the curious and inquisitive, including children and young adults. Each patient is responsible for making sure that no one else has access to or uses his or her prescribed medical cannabis.

In the event you suspect or learn that your medical cannabis has been stolen or misappropriated or is the subject of any illicit activity, contact your local law enforcement immediately.

To keep your medical cannabis secure:

  • Store cannabis in its original tamper-evident container
  • Do not remove the label from the container
  • Keep it in a secure area, away from children
  • Consider using a third-party medical cannabis storage product

Must prevent children from obtaining and using medical cannabis unless such child is the qualifying patient. 


Safely and Legally Possessing Medical Cannabis in Maryland

  • Patients and caregivers are subject to a 30-day supply purchase limit:
    • 120 grams of dried flower OR
    • 36 grams of a THC product
  • It is illegal to possess or use cannabis if you do not have a debilitating medical condition and are not a registered qualifying patient or caregiver 
  • Patients and caregivers are required to carry their registry identification card at all times when in possession of medical cannabis products

Safely and Legally Transporting Medical Cannabis

Medical cannabis must be secure, sealed, and inaccessible during transport. It is not legal to transport medical cannabis in a vehicle unless the medical cannabis is in a reasonably secured, sealed, tamper-evident container, and reasonably inaccessible while the vehicle is moving.

Patients and caregivers are not immune from the imposition of any civil, criminal, or other penalties for the following:

  • Operating, navigating, or being in actual physical control of any motor vehicle, aircraft, or boat while under the influence of medical cannabis;
  • smoking medical cannabis in a motor vehicle or any public place; 
  • Undertaking any task under the influence of medical cannabis, when doing so would constitute negligence or professional malpractice;
  • Smoking medical cannabis on private property that: (a) Is rented from a landlord, and (b) Is subject to a policy that prohibits the smoking of medical or recreational cannabis on the property

Reckless Driving or Driving Under the Influence of Cannabis Is Illegal

It is illegal to operate, navigate, or be in actual physical control of any motor vehicle, aircraft, or motorboat while under the influence of cannabis. Nothing in Maryland law prevents the arrest or prosecution of a registered qualifying patient for operating a motor vehicle under the influence of cannabis. 

Safely and Legally Administering Medical Cannabis in a Permitted Place

Medical cannabis can only be ingested in forms approved by the MMCC. No medical cannabis products may be consumed through vaporization in any public place or location where smoking is prohibited under the public health law.

A patient may consume products in his or her private residence unless the private residence is being used to provide licensed child care services or is other prohibited 

Though vaporization is generally prohibited in a hospital or healthcare facility, vaporization may occur in separate and enclosed designated smoking rooms for patients of such facilities.

Federal Laws on Cannabis

Cannabis remains a Controlled Substance under Federal Law. Thus, its possession and use are currently illegal under federal law.

Obtaining medical cannabis does not exempt a qualifying patient or caregiver from prosecution and penalties imposed by Federal law, including possessing, transporting, or using medical cannabis on any federal property. These properties include but are not limited to: federal buildings and courthouses, federal parks, federal highways, and federal military bases. It is your responsibility as a patient/caregiver to know the locations under federal jurisdiction.

Always seek the advice of your attorney before purchasing, possessing or using cannabis and regarding the resulting risks and penalties that may be imposed by the federal government. The information and materials provided to you by Verilife should not be used as a substitute for the information and knowledge that your attorney should provide to you.
