The science on cannabis topicals for headaches
If peppermint oil rubbed onto the forehead, neck or temples can provide headache relief, couldn’t a cannabis topical go the extra mile and dissolve the pain altogether?
For now, the health community says no, mainly because we’re missing human clinical trials to say whether cannabis applied to the skin is effective at all for headaches and migraines. But that’s not to say anecdotal data has been a dead end—in fact, just the opposite. A 2017 report amassed a large body of preliminary studies, concluding that we have enough evidence to start clinical trials on cannabis headache treatments. The report even made it a point to say that “cannabis is commonly used to self-medicate for headache disorders”.
Dr. Stefan Kuprowsky, a Vancouver-based naturopathic doctor specializing in ethnomedicine and ethnopharmacology, agrees the theory of topical cannabis relief for headaches is sound, especially given cannabis’s known anti-inflammatory benefits.
“Right now, topicals are most useful for joint-type pain, muscle pain and skin rashes such as eczema, acne and psoriasis,” he says. By extension, a cannabis product could also be helpful for headaches, which are often inflammatory in nature.
