Even as more and more states allow their residents to use marijuana, the federal government is continuing to obstruct scientists from studying whether the drug is good or bad for people’s health.
A report published last week by the National Academies of Sciences, Engineering and Medicine points out that scientists who want to study cannabis have to seek approvals from federal, state and local agencies and depend on just one lab, at the University of Mississippi, for samples. As a result, far too little is known about the health effects of a substance that 28 states have decided can be used as medicine and eight states and the District of Columbia have approved for recreational use.
The situation is so absurd, the report says, that chemists and brain researchers are not allowed to study cannabis concentrates and edibles. Yet those forms of the drug are widely used. For example, in Colorado, where voters decided to create a regulated market for marijuana in 2012, sales of concentrates reached $60.5 million in just the first three months of last year.
