Fentanyl Test Strips

Fentanyl Test Strips

The answer to uncertainty

Fentanyl test strips play a critical role in harm reduction initiatives. Test strips are invaluable tools designed to detect the presence of fentanyl, a potent synthetic opioid, in illicit drugs.

They can be used to check for fentanyl in substances like heroin, cocaine, or other drugs, helping to prevent accidental overdoses and deaths.

Fentanyl test strips allow individuals to make informed decisions about drug use, so they can take necessary precautions if fentanyl is detected. By promoting safer drug use practices, fentanyl test strips can save lives and curb the devastating impact of the opioid epidemic.

Remember, fentanyl test strips are not foolproof and may not detect all forms of fentanyl. Always use caution when handling unknown substances, and never use drugs alone. If you suspect fentanyl or other dangerous substances are present, it’s best to avoid using the substance altogether.

Whether you’re using drugs or care about someone who does, Minnesota has many resources to offer.

Test Strip FAQs

A quick look at the basics

What are fentanyl test strips?

Fentanyl test strips (FTS) are a low-cost method of helping prevent drug overdoses and reducing harm. FTS are small strips of paper that can detect the presence of fentanyl in all different kinds of drugs (cocaine, methamphetamine, heroin, etc.) and drug forms (pills, powder, and injectables). FTS provide people who use drugs and communities with important information about fentanyl in the illicit drug supply so they can take steps to reduce the risk of overdose.

Are fentanyl test strips difficult to use?

Not at all. The process is simple, but it’s important to carefully follow the instructions.

Why do I need to crush a pill before I test it?
Test strips require water to work. Crushing the entire pill and diluting it in water makes sure you’re testing the entire dose, and not just a portion of a badly mixed pill. See the chocolate cookie effect graphic on CDC's website.
Are fentanyl test strips legal in Minnesota?

Fentanyl test strips (FTS) are now legal to possess, carry, and distribute in Minnesota and are an important tool in preventing drug overdose. To learn more about FTS and where you can access them for free in Minnesota, please contact the MDH Drug Overdose Prevention Unit by email at

Will test strips tell me exactly how much fentanyl is in the drug?

Fentanyl test strips (FTS) have some known limitations. They can determine whether a pill contains fentanyl, but cannot measure the quantity or potency of fentanyl present in a drug sample.
