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. âscleroticâ) nerves lose their ability to transmit signals, and this results in a wide array of bad results, including numbness, dizziness, itching, and blurred vision. More than half of people who suffer from MSÂ experience pain, muscle stiffness or spasticity, and cognitive impairment.

Itâs those last three symptoms that have been most studied in relation to medical marijuana.
Whatâs the Good News? Cannabis 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 âhighly significantâ difference in spasticity between cannabis users and nonusers. Another quantified that difference as an almost twofold improvement.
What is felt, however, is not necessarily what can be proven. Despite patients reporting strong improvements, a European study from 2005 could only determine a âsmall treatment effectâ by objective measures.
And thereâs more:
The same studies found reduced pain and improved sleep.
Whatâs the Bad News? Weed can addle your brains.
In the past five years, the first studies to specifically examine the effect of cannabis on the mental clarity of MS patients have emerged. And they confirm that cannabis can worsen the cognitive problems caused by the disease. A small study from 2011 concluded that patients who treated their MS with âstreet cannabisâ (how charmingly lurid!) experienced âsignificantly worseâ mental functions, such as processing speed, memory, and executive functions. They were also twice as likely as nonusers to be cognitively impaired. An even smaller study from 2014 found similar results.
