Multiple sclerosis spasticity

Muscle stiffness and spasm in multiple sclerosis. Substantial evidence for patient-reported improvement; weaker for clinician-measured.

Substantial evidenceStrong evidence from randomized controlled trials, with very few or no credible opposing findings.

What the evidence says

NASEM 2017: substantial evidence for improving patient-reported MS spasticity symptoms with oral cannabinoids. Only limited evidence for clinician-measured spasticity.

NASEM drew a careful distinction here that is worth preserving. There is substantial evidence that oral cannabinoids improve patient-reported MS spasticity symptoms — how the spasticity feels to the person living with it. There is only limited evidence for improvement in clinician-measured spasticity.

That gap is not a reason to dismiss the benefit. It does mean that objective measures may not move much even when someone reports feeling considerably better.

Nabiximols (Sativex), an oromucosal THC:CBD spray, is approved for MS spasticity in the UK, Canada, and the EU. It is not FDA-approved in the United States.

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

  • 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.

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

    Swallowed softgel or capsule. Behaves like an edible with pharmacy-style consistency.

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

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