In one of the most comprehensive studies of recent research on the health effects of recreational and therapeutic cannabis use, a new report from the National Academies of Sciences, Engineering, and Medicine offers a rigorous review of relevant scientific research published since 1999. This report summarizes the current state of evidence regarding what is known about the health impacts of cannabis and cannabis-derived products, including effects related to therapeutic uses of cannabis and potential health risks related to certain cancers, diseases, mental health disorders, and injuries. Areas in need of additional research and current barriers to conducting cannabis research are also covered in this comprehensive report.
There are several challenges and barriers in conducting cannabis and cannabinoid research, including:
• There are specific regulatory barriers, including the classification of cannabis as a Schedule I substance, that impede the
advancement of cannabis and cannabinoid research
• It is often difficult for researchers to gain access to the quantity, quality, and type of cannabis product necessary to address
specific research questions on the health effects of cannabis use
• A diverse network of funders is needed to support cannabis and cannabinoid research that explores the beneficial and
harmful effects of cannabis use
• To develop conclusive evidence for the effects of cannabis use for short- and long-term health outcomes, improvements
and standardization in research methodology (including those used in controlled trials and observational studies) are
Drug overdose, driven largely by overdose related to the use of opioids, is now the leading cause of unintentional injury death in the United States.
