Announcement: NIDA establishing 5mg of THC as the standard unit for research

The National Institute on Drug Abuse (NIDA), along with the National Cancer Institute, the National Heart, Lung, and Blood Institute, and the National Institute of Mental Health, published a notice in the National Institutes of Health Guide directing researchers funded by these institutes to measure and report their findings from clinical research on cannabis using a standard unit of THC of 5 milligrams (mg). NIDA Director Dr. Nora Volkow wrote that “utilizing a THC standard unit in cannabis research will help us gain a better understanding of the effects of cumulative THC exposure.” The 5mg standard unit will only apply to THC, not to other psychoactive constituents of the cannabis plant such as cannabidiol (CBD).
