Report Calls For More Medical Marijuana Reasearch

Think about this before that next puff of medical marijuana. For some, medical marijuana can ease chronic pain and might help some people sleep, but it's also likely to raise the risk of triggering schizophrenia and a heart attacks.

Those are among the conclusions about marijuana reached by a federal advisory panel in a recently released report. The experts also called for a broader national effort to find out more about marijuana and its chemical cousins.

There is a federally controlled limit on marijuana research and CBS News reports the current lack of scientific information "poses a public health risk,". The report was released by the National Academies of Sciences, Engineering and Medicine which concluded patients, health care professionals and policy makers need more evidence to make sound decisions.
