A new study has been published in the October 8th issue of Journal Of Neurology, Neurosurgery and Psychiatry that shows doses of marijuana extract can ease muscle stiffness in people suffering from Multiple Sclerosis.

The study, conducted by researchers from the University of Plymouth in the UK, included 300 adults who suffered from MS.  Patients were selected to receive THC extract or an inactive placebo daily over the course of three months.

The doses began at 5 milligrams and increased gradually up to a maximum of 25 milligrams for two weeks, followed by 10 milligram doses for the following ten weeks.

After twelve weeks of treatment, 30% of the patients taking the THC extract reported reduced muscle stiffness.  16% of patients taking the placebo reported reduced muscle stiffness.

Patients reported noticing differences in their muscle stiffness after four and eight weeks.  Throughout the entire study, patients also reported improvements in sleep quality, muscle spasms, and overall pain.

Researcher and study author John Peter Zajicek believes the findings suggest that THC extracts could be a useful treatment method for Multiple Sclerosis sufferers.
