End Gas Station Heroin Act
United States119th CongressS-5383Senate
Updated: Aug 8, 2026
Summary
This bill amends the Controlled Substances Act to classify synthetic 7-hydroxymitragynine and mitragynine pseudoindoxyl as Schedule I controlled substances. However, it explicitly exempts these compounds when naturally occurring in kratom or finished kratom products, provided their concentrations do not exceed specific thresholds, such as 1 milligram per gram for solids or 1 milligram per milliliter for liquids. Any forms that are synthesized, chemically converted, concentrated, or otherwise manufactured are not eligible for this exemption. The legislation also expands enforcement actions against the commercial distribution of emerging synthetic opioids , commonly referred to as "gas station heroin." These "covered emerging synthetic opioids" are to be treated as Schedule I controlled substances for purposes of prohibiting and enforcing against their knowing or intentional manufacture, importation, exportation, distribution, or possession with intent to distribute. Crucially, the bill specifies that no person shall face criminal or civil enforcement solely for the purchase, receipt, simple possession, or personal use of these substances, focusing penalties on those involved in commercial supply. A "covered emerging synthetic opioid" is defined as a substance that is commercially distributed, is an opioid receptor agonist with greater potency than morphine, is produced through chemical synthesis, is not FDA-approved, and is intended for human consumption. Exclusions apply to substances approved for medical treatment, those not intended for human consumption, and natural constituents of plants unless intentionally concentrated or altered. Enforcement under this section is strictly limited to conduct related to commercial distribution.
