Inhaled cannabis reduces self-reported headache severity by 47.3% and migraine severity by 49.6%, according to a recent study. The study also found no evidence that cannabis caused ‘overuse headache,’ a pitfall of more conventional treatments. The researchers did see patients using larger doses of cannabis over time, indicating they may be developing tolerance to the drug. The same goes for all medication over time.
There was no significant difference in pain reduction among cannabis strains that were higher or lower in levels of tetrahydrocannabinol (THC) and cannabidiol (CBD), two of the most commonly studied chemical constituents in cannabis, also known as cannabinoids. Since cannabis is made up of over 100 cannabinoids, this finding suggests that different cannabinoids or other constituents like terpenes may play the central role in headache and migraine relief.
The study, published online recently in the Journal of Pain, is the first to use big data from headache and migraine patients using cannabis in real time. Previous studies have asked patients to recall the effect of cannabis use in the past. There has been one clinical trial indicating that cannabis was better than ibuprofen in alleviating headache, but it used nabilone, a synthetic cannabinoid drug.
Inhaled cannabis reduces self-reported headache severity by 47.3% and migraine severity by 49.6%, according to a recent study led by Carrie Cuttler, a Washington State University assistant professor of psychology.
“We were motivated to do this study because a substantial number of people say they use cannabis for headache and migraine, but surprisingly few studies had addressed the topic,” said Cuttler, the lead author on the paper.”
The study found a small gender difference with significantly more sessions involving headache reduction reported by men (90.0%) than by women (89.1%). The researchers also noted that cannabis concentrates, such as cannabis oil, produced a larger reduction in headache severity ratings than cannabis flower.
Researchers analyzed archival data from the Strainprint app, which allows patients to track symptoms before and after using medical cannabis purchased from Canadian producers and distributors. The information was submitted by more than 1,300 patients who used the app over 12,200 times to track changes in headache from before to after cannabis use, and another 653 who used the app more than 7,400 times to track changes in migraine severity.
Cannabis also has many other healing properties. A study conducted by Harvard University showed that those who had smoked weed at some point in their life had a mean sperm concentration of 62.7 million sperm per milliliter (mL) of ejaculate, while men who’d avoided marijuana entirely had mean concentrations of 45.4 million/mL.
