 London’s cocaine problem could become an eel problem.  According to Business Insider, high levels of the Class A drug have been detected in the water of the U K. city’s Thames river.

A lot of the triggers and the ways that cocaine affects the system is really primal,” James Robson, a senior curator at the SEA LIFE London aquarium, told Business Insider  For the numerous eels in the Thames — who, according to the Independent, recolonized the Thames Estuary “after it was considered ‘biologically dead’ in the 1960s” — this would likely mean “hyperactive” behavior  In response to growing concern about the level of drugs in the Thames, a group of biologists at the University of Naples Federico II conducted an experiment with eels and cocaine-laced water in June 2018 and wrote up their results for the journal Science of the Total Environment  For the study, the biologists left live European eels in water that had a small dose of cocaine, reportedly comparable to what is found in the Thames, reports The Independent The eels in the cocaine water appeared more hyperactive to the biologists than the eels in cocaine-free water The drug also caused serious injury to the eels’ skeletal muscle, which was slow to heal after the eels were removed from the water with the cocaine  “This study shows that even low environmental concentrations of cocaine cause severe damage to the morphology and physiology of the skeletal muscle of the silver eel, confirming the harmful impact of cocaine in the environment that potentially affects the survival of this species,” the 2018 report reads  However, Robson told Business Insider that the eels in this study had more exposure to cocaine than the eels of the Thames, and that Thames eels are not likely being affected in the same way  “You haven’t got a lot of disco-dancing fish down the bottom of the Thames,” he said  The aquarium curator added that animal lovers and conservationists should be more concerned about the effects of plastics pollution and climate change on London’s sea life, since both of these threats are capable of doing far more damage to eels, fish and other animals than cocaine
