A major new analysis published in JAMA examined more than 2,500 scientific papers from the last 15 years, including other reviews, clinical trials and guidelines focused on medical marijuana.

"While many people turn to cannabis seeking relief, our review highlights significant gaps between public perception and scientific evidence regarding its effectiveness for most medical conditions," Dr. Michael Hsu of University of California – Los Angeles (UCLA) Health Sciences, author of the study, said in a press release.

The researchers — led by UCLA with contributions from Harvard, UC San Francisco, Washington University School of Medicine and New York University — set out to determine how strong the research is on the effectiveness of medical cannabis and to offer evidence-based clinical guidance.

The review found that evidence supporting most medical uses of cannabis or cannabinoids is limited or insufficient, the release stated.

"Whenever a substance is widely used, there is likely to be a very wide set of outcomes," Alex Dimitriu, MD, double board-certified in Psychiatry and Sleep Medicine and founder of Menlo Park Psychiatry & Sleep Medicine, told Fox News Digital.

"Cannabis is now used by about 15 to 25% of U.S. adults in the past year, for various reasons ranging from recreational to medicinal. This study points to the reality that this widely used substance is not a panacea," said Dimitriu, who was not involved in the study.

There are very few conditions for which cannabinoid therapies have clear, well-established benefits backed by high-quality clinical data, according to the researchers.

The strongest evidence supports FDA-approved cannabinoid medications for treating specific conditions, including HIV/AIDS-related appetite loss, chemotherapy-induced nausea and vomiting, and certain severe pediatric seizure disorders.
