Fentanyl is an opioid, like heroin or morphine – but it is 50-100 times stronger. Illegally manufactured fentanyl has been increasingly added to street drugs like cocaine, heroin, and methamphetamine, making them cheaper, more addictive, and more lethal. This has caused a significant spike in accidental overdose deaths, as people taking a drug laced with fentanyl were not even aware that it was present.
Because it is not recognizable by sight, smell, or taste, the only way to identify the presence of fentanyl is by using test strips.
