SACRAMENTO, Feb. 18 (UPI) -- U.S. researchers said there is reasonable evidence that marijuana is a promising treatment for some specific, pain-related medical conditions.
Researchers at the University of California's Center for Medicinal Cannabis Research completed five scientific clinical trials, with more in progress.
The studies showed that marijuana can be helpful in easing pain in selected syndromes caused by injury or diseases of the nervous system and possibly for painful muscle spasms due to multiple sclerosis, the researchers said.
"We focused on illnesses where current medical treatment does not provide adequate relief or coverage of symptoms," Dr. Igor Grant of the University of California, San Diego, School of Medicine said in a statement. "These findings provide a strong, science-based context in which policymakers and the public can begin discussing the place of cannabis in medical care."
The researchers presented their findings to the California Legislature. The findings are also at http://www.cmcr.ucsd.edu.
