Short answer
Reddit threads about cannabis for muscle spasms report relief in some users and no change in others. No cannabis product holds FDA approval for muscle spasms. The trial base is largest for spasticity from multiple sclerosis, and the results are mixed. Reddit posts are not trials. Dose, product, and condition differ from post to post.

What people post
Threads cluster in r/MultipleSclerosis, r/spinalcordinjuries, r/ChronicPain, r/trees, and state medical cannabis subreddits. Claims repeat across them:
- 1:1 and high-CBD tinctures and gummies get named for night spasms.
- Some users say THC does the work and CBD alone does little.
- Vape and inhalable forms get described as fast, minutes to onset.
- Edibles get described as slow, 1 to 2 hours, and easy to overdo.
- Topicals get mixed reviews, with users reporting help for skin and joint pain more than deep spasm.
The sample is skewed. People who got no benefit stop posting. Nobody in a thread knows the THC mg, the batch, or the lab result.
What trials show
Trials of multiple sclerosis spasticity use nabiximols, a THC and CBD oromucosal spray, oral THC, and nabilone. Cochrane reviews of those trials report gains on patient-rated spasticity scales and smaller or absent changes on clinician-rated scales such as the Ashworth scale. Nabiximols is not sold in the US. Dronabinol and nabilone carry FDA labeling for chemotherapy-induced nausea and vomiting, and dronabinol also for AIDS-related weight loss. Spasticity is not a labeled use. Epidiolex, a CBD drug, is approved for three seizure conditions. That approval does not extend to spasms.

Convenience as the deciding factor
Access shapes what people try. Hemp-derived THC sold under the 2018 Farm Bill ships by mail to most states, which removes the dispensary trip. State medical programs require a card, a renewal, and a shop visit. Delivery and curbside pickup cut that time. Format matters too. A 10 mg gummy or a marked dropper of tincture doses at home. Flower needs a grinder, a lighter, and a room. Users in threads cite price per mg, shipping time, and stock status as reasons to switch products. Convenience decides what people buy. It does not decide whether the product works.
Check before you buy
- Lab report with batch number, cannabinoids, pesticides, solvents, microbials.
- mg per dose, not mg per package.
- CBD to THC ratio.
- State rules: medical card, possession limit, hemp versus cannabis.
- Interactions with baclofen, tizanidine, clonazepam, and other spasm drugs. Ask the prescriber.
Side effects named in trials and in threads: dizziness, dry mouth, fatigue, memory change, and worse balance in some users.
