The Marihuana for Medical Purposes Regulations (MMPR) was a set of Canadian regulations enacted in July 2013 concerning the production, distribution and use of medical marijuana. (Note: The government of Canada and some other civic agencies' Web sites use the spelling "marihuana" but most other Canadians, including news agencies, use the United States' spelling of marijuana.) The law was struck down as unconstitutional by the Federal Courts due to the inability for patients to grow their own medicine. The new act put forward was the ACMPR.

Under the MMPR, Health Canada maintained a list of authorized licensed producers of medical marihuana. While the MMPR originally only contemplated the sale of dried marijuana, amendments allowed patients to turn their marijuana into products such as edibles and cannabis oil.
