FILE - This Jan. 31, 2019 file photo shows a display of fentanyl and meth that was seized by Customs and Border Protection officers over the weekend at the Nogales Port of Entry at a press conference in Nogales, Ariz. Law enforcement officers in the U.S. Southwest say they have also seen fentanyl-laced pills mimicking Vicodin pain medicine and Xanax anti-anxiety tablets, as well as fentanyl powder to mix with heroin for an extra kick. Officers say that because the tablets are designed to look like prescription medicine, consumers often don't know they are swallowing fentanyl. And because they are made without any kind of quality control, taking them is like Russian roulette because the amount of fentanyl in each can vary widely.
