New drug-detecting tool could help save lives
The landscape of the illegal drug trade changes constantly, particularly amid the current opioid crisis. Law-enforcement officers regularly find or confiscate pills, powders, and other substances and need to know their composition as quickly as possible to determine legal charges and sometimes to issue lifesaving warnings. Carfentanil is a case in point. This cousin to […]
