For the first time in United States history, there was over 100,000 overdose deaths in a 12-month period. Fentanyl is increasingly responsible for the growing amount of accidental overdoses. Currently, more than 67% of drug overdoses involve fentanyl. 

It is now more important than ever to know the risk of contamination of street drugs, signs of an overdose, and to carry naloxone. 

Fentanyl Forms and Appearance

In the last few years, fentanyl has expanded from the East Coast to the West Coast and is found in all cities and within many rural communities. Fentanyl is found in various forms, including:

  • Pills sold as fake oxycodone, Xanax and sought after medications (left) 
  • Powder form; sometimes mixed into other drugs such as cocaine, crystal meth, and heroin. When sold as a powder, fentanyl can look varying levels of off-white to light brown. When it is mixed into other powders, fentanyl tends to bring an off-brown color to the mixture.
  • Prescribed fentanyl patches, but are mainly found in clinical settings.

Fentanyl Test Strips and Harm Reduction


Fentanyl test strips are a tool to test unregulated drugs for the contamination of fentanyl and various fentanyl analogs in powder and pill form. While helpful, it is important to keep the following notes in mind:

  • Fentanyl test strips do not provide an amount or quantity of fentanyl present in the substance, which means there could be a lethal dose. They also do not test for all the fentanyl analogs. A negative result does not guarantee the substance being tested is free from fentanyl or other synthetic opioids.
  • When using unregulated drugs, it is vital to employ safer drug use practices. The fentanyl test strips should not provide a false sense of security and should always be used in addition to safer drug use practices.

The effects of taking fentanyl with other drugs – including over-the-counter or prescribed medications – can be unpredictable and dangerous, and could cause:

Fentanyl + alcohol may increase the risk of respiratory depression and possible overdose.

Fentanyl + benzodiazepines: may add to the sedative effects and diminished breathing and possible overdose.
