Here’s how you die: Sitting on a couch and leaning over a coffee table in your living room, you barely have time to sit up straight after inhaling lines of cocaine laid out on a mirror, coke that you weren’t aware was laced with fentanyl. Before your friend can reach for a cell phone to call 911, your blood pressure plummets and your breathing slows. You don’t realize it, but fluid is filling your lungs. Lacking oxygen, your fingertips and lips are turning blue, and your brain is beginning to malfunction. As your heart rate drops, blood seeps from your nose and mouth, along with a white foam. You stop breathing and slip into cardiac arrest.
