Animal Tranquilizer in Street Drugs Sparks Overdose Crisis in SF

U.S. drug gangs are mixing the potent sedative medetomidine into street drugs like fentanyl, causing a surge in overdoses and severe health complications. This new combination, which began causing mass overdoses in late April, is difficult to detect and treat, complicating medical responses. Public health officials are issuing warnings as the toxic drug supply grows more dangerous, with similar outbreaks reported in Chicago, Pittsburgh, and Toronto. Experts are urging better preparedness for emergency treatments and cautioning drug users about the heightened risks.
