Researchers at the Oswaldo Cruz Institute in Brazil found cocaine in 13 Brazilian Sharpnose sharks caught off the coast of Rio de Janeiro.

Sharks off the coast of Brazil's party city Rio de Janeiro have tested positive for cocaine. The predators were consuming the potent stimulant due to its continuous release from inadequate sewage treatment facilities and clandestine refining operations,

A team of marine biologists and ecotoxicologists affiliated with several institutions in Brazil has found cocaine in muscle and liver samples collected from Brazilian Sharpnose sharks harvested off the coast of Rio de Janeiro.

A team of researchers with Brazil’s Oswaldo Cruz Institute has detected cocaine in 13 specimens of the Brazilian sharpnose shark found off the coast of Rio de Janeiro.

Cocaine has been detected in sharks for the first time, but scientists aren’t sure of the impact Sharks swimming off the cost of Brazil have something a little startling coursing through their systems: cocaine.

Scientists are blown away after finding significant traces of cocaine in a small sample of sharks from the waters off the coast of Rio de Janeiro. In a study published online last week, researchers reported the presence of the unfiltered drug in the liver and muscle tissues of all 13 Brazilian sharpnose sharks they tested.

Researchers have confirmed the presence of cocaine in sharks off the coast of Rio de Janeiro, though questions remain about the effects of the drug.

Off the coast of Brazil, researchers have reported a group of free-range Brazilian Sharpnose sharks that tested positive for cocaine and benzoylecgonine, which is the major metabolite of cocaine. The latest discovery of cocaine and its metabolite in free-range sharks and its findings are the first to date and were published on Science Direct.

Scientists have found traces of cocaine in wild sharks off the coast of Brazil. A study from the Oswaldo Cruz Foundation found high levels of the drug in the tissue of these wild marine animals. Researchers tested 13 Brazilian sharpnose sharks caught in the waters around Rio de Janeiro which they bought from fishers between September 2021 and August 2023.

No, Cocaine Shark is not a sequel to the recent Cocaine Bear movie (based on a true story). It is, however, a real thing. Researchers from the Oswaldo Cruz Foundation recently detected cocaine in Brazilian sharpnose sharks living off the coast of Rio de Janeiro.
