NARRATOR: It was designed for use in surgery
and to treat the most severe forms of pain.

found a profitable way to market related opioid medications
outside hospital settings.
Since I've been on this new pain medication

NARRATOR: Prescription surged, and patients

Less than 1% of patients taking opioids actually
become addicted.
NARRATOR: They were very wrong.
As fatal overdoses skyrocketed, doctors made prescription
opioids harder to get.
Addicts turned to heroin, and the crisis got worse.

Potent, cheap, and readily available on the streets
without a prescription.
In the US, overdose rates exploded to record highs.
But here in Mexico, fentanyl became a boon
to the underworld economy.
