Drug Checking Technologies Program

Drug Checking Technologies Program is a grant from the Wisconsin Department of Health Services that funds organizations in Wisconsin implementing drug checking services to reduce overdose deaths and help people who use drugs make better-informed decisions about the substances they consume.

Drug checking technologies — including fentanyl test strips and other tools — provide information about what substances are present in a drug supply, allowing for harm reduction interventions in communities with high rates of illicit drug use. The program supports Wisconsin's broader substance use prevention and overdose prevention strategy, including fentanyl detection efforts and community-based harm reduction models.

Eligible applicants are organizations in Wisconsin implementing qualifying drug checking services. The application deadline was April 19, 2026. Award amounts are not specified.

Unexpected and dangerous substances may still be present in a drug supply even if they came from a trusted source. CAUTION: The accuracy of drug checking technologies is not guaranteed. People can overdose or experience other harm like infections or diseases even if the drug checking technology says the drug of concern is not present in the drug supply.

The safest practice is to avoid using drugs altogether. It’s dangerous to use drugs when alone. If a trusted family member or friend is around and alert, they can look for the signs of a drug overdose and help if needed.

If a trusted family member or friend is not available, call Never Use Alone or SafeSpot .
