Why are drug dealers putting fentanyl in everything? (Part 1)

Isn't it bad business to kill your own customers? In part one of our answer to this question, we talk to reporter Ben Westhoff, who helps us understand how Fentanyl became a street drug in the first place. He'll share recordings taped in a Chinese Fentanyl lab, and explain why some dealers might want to poison their own customers with the drug.
