“Anti-anxiety drugs find their way into wastewater where they make fish more fearless and antisocial, with potentially serious ecological consequences, researchers said Thursday. Sientists examining perch exposed to the sedative Oxazepam — which, like many medications, passes through the human body — found that it made them more likely to leave their school and strike out on their own. With the use of such drugs on the rise, in Sweden and elsewhere, the researchers said the changes in the fish could be a global phenomenon, adding that more research is necessary before broad-based conclusions can be drawn.”
