According to a report that was based on five separate clinical trials findings marijuana does have medicinal properties. Report of this study conducted by UC San Diego was submitted to the Legislature on Wednesday.

Dr Igor Grant, executive vice chairman of the department of psychiatry at the UC San Diego School of Medicine and director of the school's Center for Medicinal Cannabis Research, said, “These findings provide a strong, science-based context in which policymakers and the public can begin discussing the place of cannabis in medical care."

Earlier studies that were conducted over 10 years now and were funded by the state said that marijuana was effective alone or in combination with other drugs. It proved useful in conditions such as nerve pain caused by HIV and multiple sclerosis muscle spasms.

Apart from California being the first state to legalize marijuana's medical use, it is also the only state to have used public money on researching marijuana’s medicinal properties.

State Sen. Mark Leno, D-San Francisco said, "This study confirms all of the anecdotal evidence of suffering eased by marijuana.”

National Institute on Drug Abuse remains the only legal source of marijuana for such. The institute manages a farm at the University of Mississippi.
