STOP Fentanyl and Xylazine Act

This bill clarifies that equipment designed to detect fentanyl or xylazine in substances is exempt from certain restrictions under the Controlled Substances Act. It amends Section 422 to explicitly state that possessing, selling, or transporting such testing equipment does not violate federal law. The change directly affects harm reduction organizations, first responders, and public health groups using these tools to identify dangerous substances and prevent overdoses.
