Multiple sclerosis is a neurological disease in which the immune system attacks the fatty protein that protects our nerve cells. The exposed and damaged (i.e. “sclerotic”) nerves lose their ability to transmit signals, and this results in a wide array bad results, including numbness, dizziness, itching, and blurred vision. More than half of people who suffer from MS experience pain, muscle stiffness or spasticity, and cognitive impairment.
It’s those last three symptoms that have been most studied in relation to medical marijuana.
What’s the Good News?
Can>nabis eases spasticity and muscle stiffness:
In double-blind, placebo controlled trials, MS patients who use cannabis oil, synthetic THC, or an oral-spray blend of THC and CBD have reported feeling relief from muscle stiffness and spasms. At least one has shown a “highly significant” difference in spasticity between cannabis users and nonusers. Another quantified that difference as an almost twofold improvement.
