Marijuana may give relief to migraine sufferers, according to research published online in Pharmacotherapy.
The research included 121 patients diagnosed with migraines and treated with medical marijuana between January 2010 and September 2014. Patients in the study used both inhaled marijuana and edible marijuana. The researchers said inhaled marijuana seemed to be preferred for treating current headaches, and edibles seemed to be favored for headache prevention.
The researchers found that 103 study participants said they had a decrease in their monthly migraines. Fifteen patients said they had the same number of migraines, and 3 reported an increase in headaches. Overall, the patients’ number of migraines fell from 10.4 to 4.6 per month, which is statistically and clinically significant.
“There was a substantial improvement for patients in their ability to function and feel better,” senior author Laura Borgelt, PharmD, a professor in the School of Pharmacy and Pharmaceutical Sciences at the University of Colorado Anschutz Medical Campus in Aurora, said in a university news release. “Like any drug, marijuana has potential benefits and potential risks. It’s important for people to be aware that using medical marijuana can also have adverse effects.”
