The Department of Health and Human Services has issued a long-awaited report on barriers to researching the medical use of marijuana. The report is required under the Medical Marijuana and Cannabidiol Research Expansion Act, which passed in 2022. Identified barriers include confusion created by the different definitions around hemp and marijuana under federal law, lack of access to state-legal products for research purposes and additional hoops scientists have to jump through to study a Schedule I drug.  See the Politico article here.
