"I received a call that people were pouring into the emergency room dead on arrival after taking counterfeit Norco laced with fentanyl," Sacramento County Public Health Officer Dr. Olivia Kasirye told health professionals gathered at the Prescription Drug Awareness Conference held at Sacramento State University on May 20. Trying desperately to prevent additional deaths, Kasirye says she went into overdrive to get the word out about this dangerous batch of fake Norco. Norco is a prescription painkiller, but this batch contained fentanyl, a powerful painkiller hundreds of times stronger than heroin.
