Sharks in the Bahamas Are Full of Cocaine, Caffeine, and Painkillers

On Tuesday, researchers led by biologist Natascha Wosnick reported that sharks near Eleuthera Island in the Bahamas tested positive for human pharmaceuticals and cocaine, published in Environmental Pollution.
The researchers noted that drugs likely enter water from people "peeing and dumping sewage," while lost or discarded drug shipments also represent potential contamination sources.
Nearly a third of the 85 sharks tested positive for caffeine, acetaminophen, and diclofenac, with contaminated specimens showing metabolic shifts tied to stress and energy use.
Marine scientists warn that ingestion of these contaminants might be "modifying the sharks' behavior," prompting urgent calls to address pollution in ecosystems often perceived as pristine.
Similar detections in Brazilian sharpnose sharks, where 92 percent of muscle samples contained cocaine, reveal these contaminants of emerging concern represent a global ecological challenge.
