Fentanyl Test Strips

Fentanyl Test Strips


Fentanyl test strips (FTS) are a low-cost harm reduction tool that can be used to prevent overdoses in combination with other strategies. FTS are small strips of paper that can detect the presence of fentanyl in different kinds of drugs (cocaine, methamphetamine, heroin, etc.) and drug forms (pills, powder, and injectables).

How to Use Fentanyl Test Strips*

* FTS may not work in all cases

  • FTS do not differentiate between fentanyl and fentanyl analogs and may not identify the presence of some analogs (e.g., alfentanil or carfentanil).
  • FTS may not work as well in the presence of large amounts of methamphetamine, MDMA, or diphenhydramine.
  • FTS can’t tell you how much fentanyl is in a sample, just if the sample contains fentanyl.
Chocolate Chip Cookie Effect: One portion of a drug may contain fentanyl, while another portion may not.
