Overdose deaths from fentanyl- laced stimulants rose 50-fold since 2010

UCLA et al found that US overdose deaths involving both fentanyl and stimulants grew more than 50-fold since 2010, from 0.6% (235 deaths) in 2010 to 32.3% (34,429 deaths) in 2021. The trend marks the 4th wave in the US overdose crisis, which began with prescription opioid deaths in the early 2000s and continued with other drugs.
