This bill, called the "End Gas Station Heroin Act," targets the sale of emerging synthetic opioids commonly sold in convenience stores and gas stations. It adds specific compounds (7-hydroxymitragynine and mitragynine pseudoindoxyl) to the list of Schedule I controlled substances, with an exception for naturally occurring kratom products that stay below certain concentration limits. The legislation also creates a broader enforcement mechanism allowing the government to treat any chemically synthesized opioid compound as Schedule I if it is more potent than morphine and sold commercially for human consumption, without requiring a formal scheduling process. Importantly, the bill protects individuals from criminal penalties for simple possession or personal use while targeting manufacturers and distributors of these drugs. The law empowers the Attorney General to enforce against commercial distribution of these substances and to establish regulations defining what qualifies as scientifically reliable evidence of drug potency.
