Researchers from the University of

clinical trial that included 30 participants who had multiple sclerosis. The
scientists hoped to understand whether smoked cannabis reduces symptoms of
spasticity, a common symptom of the disease that refers to stiffness and
involuntary muscle spasms.

specifically whether a smoked form of the drug has a beneficial effect.

“Smoking cannabis was indeed
superior to the placebo in reducing spasticity and pain, but that certainly
came at a price,” said Dr. Judy Corey-Bloom, director of the Multiple

Patients experienced less pain after
smoking, but also experienced fatigue, impairment of cognitive function,
attention and concentration.

“There can be a lot of
sources of pain with MS, from that pins and needles and burning feeling, but
also the pain from muscle stiffness,” said Corey-Bloom. “It’s
important for patients to know that pain can be treatable.”
