One of the authors of this study said in Instagram they didn’t found drugs in shark livers. She said they’ve found the cocaine in the fishes’ muscles. She said It suggests the chronic use of this substance, that is, the sharks have been full of cocaine for some time.
She also suggests that sharks, as they are at the top of the food chain, are consuming many fish and other animals impregnated with the white powder. It seems like all the animals in the sea are getting higher and higher.
