Hello. Research has found that cannabis improves dystonia. CBD is mainly responsible for providing muscle spasm relief and THC mainly for pain relief. Researchers found that CBD treatments caused significant dystonia improvements in both a 65-year-old woman and a 31-year-old man (Sandyk, Snider, Consroe & Elias, 1986). Other research studies show that THC can have positive influences to the degree of spasticity and dystonia. Along with pain, muscle spasm is the most common reason that medical cannabis is recommended and prescribed by medical professionals. I would recommend oral capsules or tablets of 1:1 CBD to THC.
