Marijuana Enforcement Division (MED) rule changes effective Dec. 1

The MED’s changes clarify that “a Medical Marijuana Store that is designated as a patient’s primary store must maintain both the physician certification required under Title 25 and, if the patient is authorized to purchase Medical Marijuana in excess of the statutory daily limits, the patient’s uniform certification form required under Title 44.” Read more in MED’s stakeholder bulletin or MED’s rules page. For information on what information patients can redact from their physician certification, review this tip from MED.

Patients are able to view or print their most recent physician certification from their Medical Marijuana Registry patient account
