Input Invited on the Establishment and Implementation of a Standard Unit Dose of THC for Cannabis Research

The National Institute on Drug Abuse (NIDA) issued a Request for Information (RFI) from the research community and any other interested parties regarding the establishment of a standard unit dose of THC in order to facilitate research on cannabis. As medical and recreational marijuana become more accessible in the United States, there is increased urgency to study its effects—both adverse and potentially therapeutic—in a systematic fashion. The lack of a standardized measure of THC in various cannabis products, makes it difficult to compare the results of different studies, especially with the “widening variety of cannabis products, such as edibles and extracts, as well as the increasing potency of cannabis available on the street and in dispensaries.”
