Researchers say there's evidence lacking that marijuana treats conditions it's prescribed for

Having chronic pain can qualify you for Arizona’s medical marijuana program. But research led by UCLA says there’s a lack of evidence that cannabis treats chronic pain and most other conditions for which it may be prescribed.

The conclusion is based on a review of thousands of articles about marijuana clinical trials, guidelines and analyses published over 15 years.

Researchers found big gaps between public perception of marijuana as medicine and scientific evidence of what it does. And they found a lack of scientific support that cannabis can help ease chronic pain, anxiety and insomnia.

The review also confirmed marijuana is an effective treatment for appetite loss caused by HIV medication, nausea from chemotherapy and certain child seizure disorders.
