The Department of Justice, Drug Enforcement Administration (DEA), is seeking contractors to conduct in vivo pharmacological studies to evaluate the abuse potential of synthetic cannabinoids and phytocannabinoids. The project aims to support domestic scheduling activities under the Controlled Substances Act (CSA) by comparing test substances to known drugs of abuse, such as THC, through various studies including locomotor activity and drug discrimination. This opportunity is critical for understanding the safety and regulatory implications of these substances, with a contract period starting from March 20, 2026, to March 19, 2027, and the possibility of four one-year extensions. Interested parties should contact Ms. Angel Barkley at angel.d.barkley@dea.gov for further details and to ensure compliance with the required Schedule I researcher registration and protocols.
