State and Federal Regulations

Massachusetts Regulations

All registered qualifying patients must notify the Massachusetts Department of Public Health:

  • Of changes in the patient’s name or address
  • If the patient ceases to have the debilitating medical condition
  • If the qualifying patient is deceased (the designated caregiver, if any, or a legal representative of the patient shall notify the Department)
  • Of a change in the designated caregiver
  • If the registry identification card is damaged, lost or stolen;
  • Of a change to the information that he or she was previously required to submit to the department;
  • A registered qualifying patient must carry his or her registration card at all times while in possession of marijuana.;
  • Caregiver must not allow a registered qualifying patient who is under 18 years of age to possess marijuana at any time when not in the presence of the personal caregiver; 

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 medicinal cannabis medicine storage product.
  • Individuals that meet the requirements set forth under the MA adult regs would be able to use marijuana.

Patients and caregivers are required to carry their registry identification card at all times when in possession of medical marijuana products.

Safely and Legally Possessing Medical Cannabis in Massachusetts

Possessing marijuana is legal for:

  • An adult 21 years of age or older
  • A registered medical marijuana patient, caregiver or agent of a registered marijuana dispensary

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

Safely and Legally Transporting Medicinal Cannabis

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

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 Massachusetts 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 Medicinal Cannabis in a Permitted Place

The law prohibits smoking medical marijuana. Medical marijuana can only be ingested in forms approved by the Massachusetts Department of Health. 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 if, 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.
