Someone you know may be using fentanyl without ever choosing it. Dealers press it into counterfeit pills and mix it into heroin, cocaine, and other street drugs. People swallow or snort it thinking it's something else. That's why the signs matter. Watch for pinpoint pupils, sudden drowsiness, slowed breathing, and confusion. Notice the small changes too: nodding off mid conversation, missing money, new secrecy. Spotting these early gives you time to act. With fentanyl, that time can be the difference between life and death.
