Fentanyl has changed what a lot of families are dealing with, and often without warning. It now shows up in counterfeit pills made to look like prescription medication, and it gets mixed into heroin, cocaine, and other street drugs. That means someone can be exposed without ever choosing to take it. We want you to know the signs, because catching them early is one of the clearest ways to keep a person alive. Small changes matter, and paying attention to them is not overreacting.
