Opioids Field Testing

Some large law enforcement agencies have recently abandoned the routine chemical field tests out of concern that officers could be exposed to opioids that can be absorbed through the skin or inhaled. Even a minute amount of the most potent drugs, such as fentanyl, can cause violent illness or death. (AP Photo/Jacquelyn Martin, File)
