Use of dried cannabis for medical purposes


The Marihuana for Medical Purposes Regulations came into effect on April 1, 2014, and was replaced in August 2016 by the Access to Cannabis for Medical Purposes Regulations. To assist its members in complying with the regulations and to ensure patient safety, the Collège des médecins du Québec produces guidelines. It provides a list of research projects underway in Quebec on the use of cannabis for medical purposes.


Any physician who wishes to familiarize himself with the new framework for prescribing cannabis must read the document Guidelines concerning the prescription of dried cannabis for medical purposes in full. A summary is provided below.

  1. The use of cannabis for medical purposes is not a recognized treatment.
  2. An unrecognized treatment can only be used within a research framework.
  3. As of April 1, 2014 and until further notice, only certain indications will have to be considered.
  4. Before considering the use of cannabis to treat a medical condition provided for in the previous regulations, other therapeutic options must be considered, in particular other forms of cannabinoids authorized for prescription by Health Canada.
  5. A physician who is asked to prescribe cannabis must read the medical literature and inform his patient that cannabis can only be prescribed within the framework of a research project; and that the patient must purchase it from a producer authorized by Health Canada.
  6. Before prescribing cannabis, the physician must obtain the written consent of the patient participating in a research project (consent form) and carry out a complete medical assessment.
  7. When a physician prescribes cannabis, he must plan the patient’s follow-up and keep a register of all patients for whom he has prescribed cannabis.
  8. A physician may not supply the patient directly with cannabis or deal in cannabis or cannabinoids.
  9. A physician may not become or apply to become a cannabis producer.
  10. The prescribing physician must collaborate with the Collège and its partners in the collection of scientific data in order to improve knowledge and practices with respect to the use of cannabis for medical purposes and to ensure patient safety.
Research projects underway in Quebec

One research project is currently underway in Quebec:
Project title: “Quebec Cannabis Register: A Research Database on the Use of Dried Cannabis for Medical Purposes”

Lead investigator: Dr. Mark A. Ware, McGill University Health Centre (MUHC) and the Canadian Consortium for the Investigation of Cannabinoids (CCIC)

The CMQ supports this research project. While allowing the physician to comply with his professional ethics, this initiative should make it possible to:

  • systematically collect data across Quebec on the indications, dosages, benefits or side effects of the products used;
  • develop future research;
  • ensure safer access to products, since the research database will be used in the development of a drug monitoring program.

For information about this project, consult the Quebec registry Web page.
