The purpose of this Request for Information (RFI) is to invite input on the establishment and implementation of a standard unit dose of THC for cannabis research.
Note: It is important to read this entire RFI notice to ensure how to submit adequate responses and to understand how the responses will be utilized.
As the diversity of products, potency, and use of cannabis increase, research grows ever more critical to determine both the adverse health effects and therapeutic potential of cannabis and its constituents. The potency of such products has increased rapidly: the THC concentration in commonly cultivated marijuana plants increased four-fold between 1995 and 2018 (From 4 to 16); marijuana available in dispensaries in some states has average concentrations of THC between 17.7 percent and 23.2 percent. The consequences of this change in potency are not yet well understood.
In their Recommendations for NIDA’s Cannabis Policy Research Agenda, theCannabis Policy Research Workgroup of the National Advisory Council on Drug Abuse recommended that NIDA explore the possibility of constructing a standardized dose similar to that for alcohol (the standard drink), tobacco (a cigarette), or opioids (morphine milligram equivalents) for researchers to employ in analyzing use and for users to understand their consumption. In February 2020, NIDA Director Nora Volkow published a commentary highlighting the importance of a standard unit dose for cannabis research. While establishment of a standard unit dose for cannabis is complicated by variability due to different routes of administration, different constituents in the product, as well as other factors including the behavior of the users, such a unit is critical for conducting rigorous cannabis research. Recognizing that a perfect measure may not be attainable at the current time, NIDA still believes that a standard dose would improve measures of outcomes in relation to exposure; and thus, could inform policy and public health strategies around cannabis use.
This RFI seeks input from stakeholders throughout the scientific research community and any other interested parties regarding the establishment of a standard unit dose of THC for cannabis research.
The NIH seeks comments on any of the following topics:
