​♦️Cocaine sharks. (Adapted news for pre-intermediate english students). Audio.

Scientists have found cocaine in  sharks  near  Brazil.  They  tested  13  Brazilian sharpnose sharks from near Rio de Janeiro. The  sharks  had  high  levels of cocaine in their muscles and livers, much  higher  than  other  sea animals.

The Oswaldo Cruz Foundation did this research, and it is the first time cocaine has been found in  sharks.  Experts  think cocaine enters the ocean from illegal drug labs or through the waste of drug users. Some cocaine packs lost at sea could also be a source, but this is less likely.

Sara Novais, a scientist, said these findings are important and concerning. All the female sharks tested were pregnant, but it is not clear how cocaine affects the baby sharks.

More research is needed to see if cocaine changes how sharks behave, but past studies suggest drugs can affect animals like they do humans..
