For the first time, researchers have completed a study that proves medical marijuana can treat migraines. A study like this has never been done before due to federal regulations preventing scientists in the U.S. from obtaining cannabis for research. Throughout the years, migraine and headache sufferers have turned to smoking pot to alleviate their pain, but this is the first time scientific evidence exists to back up their claims.
Researchers at the University of Colorado Anschutz Medical Campus gathered 121 participants who were diagnosed with migraines. They treated them with medical marijuana between January 2010 and September 2014, and found that their migraines were reduced from over 10 a month to less than five per month. The majority of participants — 103 of them — reported a decrease in migraines overall. And only three saw an increase in migraines over the course of the trial.
