There has been a wave of overdoses, some fatal, in the Sacramento area in California and the suspicion falls on fake Norco pills that contained fentanyl.
Forty eight opioid-related overdoses have been reported to the Sacramento County Department of Health and Human Services (DHHS) since March 23.
Fentanyl is a synthetic opioid estimated to be 80 times more potent than morphine and hundreds of times more potent than heroin.
