Menstrual cramps

Painful periods. No condition-specific evidence; covered loosely by chronic pain.

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

What the evidence says

No condition-specific evidence. Loosely covered by the chronic pain conclusion.

There is no NASEM conclusion for dysmenorrhea and no substantial trial evidence for cannabis specifically. What support exists is inherited from the broader chronic pain finding.

Topicals and suppositories are marketed for this. Evidence for both is thin.

If you might become pregnant, note that CDC and ACOG advise avoiding cannabis in pregnancy by every route, including topical.

What to ask for

This is a starting point, not a prescription. Take it to a licensed dispensary and ask to see the batch certificate of analysis.

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

  • TopicalOnset 15–60 min · lasts 2–6 h

    Creams, balms, and patches applied to skin. Non-transdermal topicals do not produce intoxication.

  • 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.

  • EdibleOnset 30–120 min · lasts 6–8 h

    Eaten or swallowed. Slow onset and long duration — and disproportionately responsible for cannabis-related emergency visits.
