Three students died and six others were hospitalized over a span of just a few months. Keith Brown, the deputy director of the Texas and Oklahoma High Intensity Drug Trafficking Area and a retired DEA executive, says all parents, students, and educators need to know just how potent fentanyl really is. Just one pill can kill.
