With classes resuming at colleges and universities, the Drug Enforcement Administration is imploring students and administrators to be wary of counterfeit pills that may contain fentanyl, a powerful synthetic opioid that can be deadly in even small amounts.

According to a survey by the DEA, about 20% of college students self-reported misusing prescription drugs.
