What the evidence says
NASEM 2017: no or insufficient evidence for cannabis in Parkinson's disease.
NASEM placed Parkinson's disease in the no-or-insufficient-evidence category, alongside dystonia, Huntington's disease, and ALS.
Some people report subjective benefit for tremor or sleep. That is not the same as demonstrated efficacy, and orthostatic hypotension and falls are meaningful risks in this population.
