Cocaine and caffeine detected in Bahamas sharks, spotlighting marine pollution

A Bahamas study of 85 sharks around Eleuthera found drugs in 28 individuals: caffeine was most common, with two sharks testing positive for cocaine and others for acetaminophen and diclofenac, suggesting pollution from wastewater and tourism; researchers warn of potential increased stress and detoxification energy use, and call for better wastewater management and more research on ecological impacts.
