Oral medical cannabis could ease MS symptoms

Evaluating 33 studies, the neurologists concluded oral cannabis extract and tetrahydrocannabinol (THC) pills may treat spasticity, pain and overactive bladder in patients with MS.

However, synthetic THC did not relieve drug-induced dyskinesias in patients with Parkinson’s disease.

The evidence was insufficient to determine if medical marijuana was safe or effective in treating motor symptoms in Huntington’s disease, tics in Tourette syndrome, cervical dystonia or epileptic seizures, the experts said.
