A study published last year by the Journal of Neurology, Neurosurgey and Psychiatry, as well as the National Institute of Health, found that cannabis can treat the primary symptom of multiple sclerosis, muscle stiffness. The study followed the gold standard of scientific research, being double-blind, placebo-controlled and used human subjects.
According to the study’s official objective; “Here we report the results of the Multiple Sclerosis and Extract of Cannabis (MUSEC) study that aimed to substantiate the patient based findings of previous studies.”
According to researchers – which examined subjects with multiple sclerosis, who were given varying doses of THC over the course of several weeks – “The rate of relief from muscle stiffness after 12 weeks was almost twice as high with CE than with placebo (29.4% vs. 15.7%; OR 2.26; 95% CI 1.24 to 4.13; p=0.004, one sided). Similar results were found after 4 weeks and 8 weeks, and also for all further CRSs. Results from the MS scales supported these findings.”
Researchers conclude; “The study met its primary objective to demonstrate the superiority of CE over placebo in the treatment of muscle stiffness in MS. This was supported by results for secondary efficacy variables. Adverse events in participants treated with CE were consistent with the known side effects of cannabinoids. No new safety concerns were observed.”
A similar study published in 2011, which also used a double-blind, placebo-controlled method, also found that cannabinoids can be beneficial to those with multiple sclerosis.
