What it does.
The HALT Fentanyl Act keeps fentanyl and the chemical cousins traffickers engineer to skirt the law on the most-controlled drug list permanently. Before this bill, the DEA had to renew that classification on a temporary basis, and every renewal window opened a legal loophole for synthesis. The law closes it for good.
Doc cosponsored. President Trump signed the bill into law as Public Law 119-26 on July 16, 2025. It sits alongside Doc's broader fentanyl and border work, including the Laken Riley Act (S. 5) and the 287(g) sheriff-participation push he has done with Kansas sheriffs.
Kansas overdose deaths from fentanyl have climbed every year since 2018. Kansas sheriffs have testified that fentanyl-laced drugs are the primary overdose driver in their counties.
