What We Really Know About Medical Cannabis: A Review of Reviews

Mixed Results

There is reasonable evidence that cannabinoids improve nausea and vomiting after chemotherapy. They might improve spasticity. There is uncertainty about whether they improve pain, but if they do, it is neuropathic pain and the benefit is likely small. Adverse effects are very common.

Smoked Cannabis Reduces MS Spasticity but Impairs Cognition

Positive with Caveats

Smoked cannabis was superior to placebo in symptom and pain reduction in participants with treatment-resistant spasticity. Future studies should examine whether different doses can result in similar beneficial effects with less cognitive impact.
