According to Wikipedia, fentanyl is an opioid used as a pain medication and together with other medications for anesthesia. Fentanyl is also made illegally and used as a recreational drug, often mixed with heroin or cocaine. It has a rapid onset and effects generally last less than an hour or two. Medically, fentanyl is used by injection, as a patch on the skin, as a nasal spray, or in the mouth.
It has become an epidemic. The government is looking for solutions on how to slow down and eventually stop the epidemic.
Particularly, the Department of Homeland security has recently contracted a Utah company, Vaporsens, to develop fentanyl sensors.
The idea is to equip first responders with the wearable sensor that will enable them to detect traces amounts of the drug.
