Study Finds Cocaine Pollution Alters Behavior of Juvenile Atlantic Salmon

A recent study published in Current Biology reveals that trace amounts of cocaine and its metabolite benzoylecgonine in freshwater environments can significantly alter the behavior of juvenile Atlantic salmon. Researchers from Swedish University of Agricultural Sciences and Griffith University used implants to simulate drug exposure, observing increased travel distances and changes in movement patterns. These behavioral shifts may affect aquatic ecosystems by disrupting predator-prey relationships and biodiversity, highlighting the need for environmental risk assessments of drug pollutants.
