Feds warn of so-called rainbow fentanyl as growing concern.
Rainbow fentanyl has appeared recently in several forms in cities across the country. Fentanyl is usually disguised in fake prescription pills and that the fakes are indistinguishable from real pills.
Provisional data from the Centers for Disease Control and Prevention indicate there were over 107,000 fatal drug overdoses in the U.S. in 2021, an increase of nearly 15% from the previous year, federal officials said. Synthetic opioids — primarily fentanyl — accounted for more than three-quarters of those deaths.
