Despite the fact that in various places, the medicinal properties of cannabis are presented as debatable, the science is quite clear that cannabis can help treat and possibly even cure a wide variety of diseases. This is precisely why many people are choosing to use medical cannabis, and even grow their own medical cannabis in if they live in a place, like Canada, where one can legally grow their own cannabis. In Canada, it can be done through the ACMPR program.

Medical reasons are why most people use cannabis, at least according to a new study published Friday in the JAMA Open Network. The study surveyed more than 165,000 men and women across the country between 2016 and 2017.

“Adults with medical conditions, especially those with respiratory conditions, cancer, and depression, were more likely to use marijuana,” the study’s authors noted in its conclusions. “At present, marijuana use prevalence decreases with age, even among people with medical conditions. Because public perceptions of marijuana are becoming more favorable and medical conditions increase with age, older adults might also become frequent consumers of marijuana.” (source)

According to the study, approximately one in four 18- to 24-year-olds use medical marijuana as opposed to just 2% of people who are at least 65 years old. The most popular way to use marijuana, across all demographics, is smoking, accounting for 77.5% of regular users. Earlier this year, Pennsylvania added anxiety disorders to a growing list of treatable symptoms in its medical marijuana program. The program currently has 23 approved conditions.
