Summary

AI-generated summary, report an error

This bill would add a class of synthetic opioids called nitazenes (2-benzylbenzimidazole opioids) to Schedule I of the Controlled Substances Act. The listing would cover substances with certain chemical structures that act on the mu-opioid receptor, including named drugs such as etonitazene, isotonitazene, and protonitazene, along with their isomers, esters, ethers, and salts. Any of these substances that were only temporarily scheduled would become permanently scheduled when the bill is enacted. The bill states that it does not allow new research with these substances without proper registration and scheduling compliance.
