The Canadian government in 2001 established regulations to expand the use of marijuana as a medicine. According to an editorial in the Canadian Medical Association Journal, "The new regulations promise more transparency in the review of applications to grow or possess medicinal marijuana, a broader definition of medical necessity, and greater latitude for physicians in determining the needs of individual patients."
