Number of Medical Marijuana Users in Canada

"Among those who used cannabis, 17.7% (representing about 420,000 Canadians or 1.6% of the Canadian population aged 15 years and older) reported doing so for medical purposes. Prevalence of use for medical purposes was similar between male and female cannabis users (17.3% versus 18.4%, respectively), while more than one in five (21.8%) cannabis users aged 25 years and older reported using it for medical purposes, representing 1.5% of all adults in this age group. The percentage of youth who used cannabis for medical purposes is not reportable.
"Half (49.7%) of those who used cannabis for medical purposes did so mainly for chronic pain caused by conditions such as arthritis, back pain and migraines, while the remaining 50.3% used cannabis primarily for one of a variety of conditions that included insomnia, depression and anxiety. These numbers do not in any way measure or reflect enrolment in the federal Medical Marijuana Access Program."
