Rapid Surge in Fentanyl-Stimulant Overdose Deaths Shakes the U.S.

Overdose deaths involving a combination of fentanyl and stimulants like cocaine and methamphetamine have increased 50-fold since 2010, according to a study by researchers at the University of California. Many recreational drug users may be unaware that their drugs are laced with fentanyl, a potent opioid that can be deadly even in small doses. This "fourth wave" of the U.S. overdose crisis poses a significant risk, as people who use stimulants may unintentionally consume fentanyl and have a low tolerance for opioids. The combination of fentanyl and stimulants presents challenges for doctors and public health officials, who are still grappling with the ongoing opioid crisis. Experts recommend using fentanyl test strips and having the overdose reversal drug Narcan on hand to prevent and respond to overdoses.
