What This Bill Would Do
This bill proposes to permanently classify a group of synthetic opioids known as 'nitazenes' as controlled substances. This change would make the manufacturing, distribution, and possession of these substances illegal under federal law.
If passed, this bill would permanently criminalize the entire class of nitazene opioids, removing them from the illicit market and subjecting anyone possessing or distributing them to federal penalties.
Who It Would Affect
Groups the bill's text would affect if enacted, as described in the record. Being affected is not a position for or against it.
Drug Enforcement Administration
The agency is tasked with enforcing the permanent Schedule I status of the entire class of nitazenes.
Medical researchers
Researchers must maintain specific federal registrations to study these substances due to their Schedule I classification.
