Fentanyl and other potent synthetic opioids ingrained in the nation's illicit drug supply are killing more people in the U.S. than any other drug has.

AUSTIN, Texas – A drug ring largely operated by current and former University of Texas students used apps and social media to sell counterfeit Adderall and Xanax often laced with fentanyl, the Department of Justice announced Friday. Justice officials said 13 people, including eight current and former students, have been charged with trafficking LSD, fentanyl and methamphetamine pills. Prasad accepted payments for the drugs via apps including Venmo and Paypal, plus in cash. Former University of Texas at San Antonio professor Rose Rodriguez-Rabin is accused of providing Prasad with methamphetamine-laced counterfeit drugs “on numerous occasions,” Sofer said.
