A pill that looks exactly like a prescription painkiller can contain fentanyl instead. That is the reality behind so many overdoses now, because fentanyl gets pressed into counterfeit tablets and mixed into other street drugs without any warning on the outside. People take a dose they never agreed to. This is why paying attention matters so much. When you notice the signs early, in yourself or in someone you love, you have a real chance to step in before things turn dangerous.
