Trafficking opioids via the dark web

Two 13-year-old boys in Park city, Utah, are among the dead from the synthetic opioid fentanyl — now the fastest-growing cause of overdoses nationwide. Authorities say another local teenager bought the drugs on the dark web using Bitcoin. That's according to Nathaniel Popper of the New York Times, who reports that the online drug trade is on track to be "even more formidable than the cartels."
