Migraine

Recurrent severe headache. Insufficient evidence specifically for migraine, despite widespread claims.

Insufficient evidenceMixed findings, a single poor-quality study, or the question has not been studied.

What the evidence says

NASEM 2017 did not find sufficient evidence for cannabis in headache or migraine. Consumer claims exceed the evidence.

Migraine is one of the most common reasons people give for using cannabis and one of the least well supported. NASEM did not reach a positive conclusion for headache or migraine.

There is a specific risk worth knowing: medication overuse headache. Frequent use of any acute headache treatment, including cannabis, can produce rebound headaches that are harder to treat than the original problem.

If you get migraines often enough to be treating them regularly, preventive treatment with an established evidence base is likely to serve you better.

Cannabinoids

  • THC

    The main intoxicating compound in cannabis. It drives most of what people mean by "high," and it is also the cannabinoid behind most documented therapeutic effects.

  • CBD

    Non-intoxicating. The only cannabis-derived compound with an FDA-approved medicine behind it, and the cannabinoid most often used to soften THC.

Terpenes to look for

Commonly present in products people choose for this. Terpene effect claims are preclinical — this is a way to find a product again, not a promise about how it will feel.

Formats

  • Vape cartridgeOnset 1–10 min · lasts 2–4 h

    Concentrated cannabis oil in a battery-powered cartridge. Discreet, potent, and easy to over-do.

  • TinctureOnset 15–90 min · lasts 4–8 h

    Liquid extract dosed by dropper. The most precise way to titrate an oral dose in small increments.
