The Trump administration told drug addiction groups that federal grant money cannot be used to distribute test strips to drug users, a policy shift raising concerns about overdose deaths. The strips allow users to check street drugs for dangerous adulterants before consumption.

The directive affects organizations nationwide that have relied on federal funding to provide harm reduction services. Test strips can detect substances like fentanyl, which has become increasingly common in street drugs and is linked to a surge in fatal overdoses across the country. Public health advocates have promoted the strips as a tool to prevent deaths among people who use drugs.

Drug addiction groups said they are reassessing their programs following the announcement. Many harm reduction organizations receive federal grants to support a range of services, including syringe exchange programs, naloxone distribution, and drug checking equipment. The policy change limits how those funds can be spent.

The administration has not specified what prompted the change or whether alternative federal support for overdose prevention will be made available. The decision comes as the United States continues to face high rates of drug overdose deaths, many involving synthetic opioids mixed into other substances without users' knowledge.

Health departments and advocacy organizations in states with high overdose rates have incorporated test strips into their public health strategies. The federal funding restriction may force these programs to seek alternative sources of support or curtail distribution efforts.
