What most people notice first is a change that does not add up. Fentanyl is now pressed into counterfeit pills and mixed into other street drugs, so a person can be exposed without ever choosing it. That is why the signs matter. We watch for pinpoint pupils, slowed or shallow breathing, extreme drowsiness, and confusion that comes on fast. Catching these early is not about panic. It is about knowing what you are seeing, and acting while there is still time.
