Cocaine and other illicit drugs in the marine environment: Potential effects and future directions.

Cocaine and its primary metabolite, benzoylecgonine, have been recently detected in sharks, indicating a growing concern over marine drug pollution. The presence of this drug in marine fauna poses risks such as physiological stress, impaired growth, reproduction, and altered behaviors, potentially leading to biodiversity loss and disrupted ecological interactions. Biomagnification may further affect higher trophic levels, including humans. Addressing this issue requires continuous monitoring, studies on physiological effects, understanding contamination routes, and improving wastewater treatment. Additionally, stricter regulations on pharmaceutical disposal are necessary to mitigate the impacts of such pollutants on marine ecosystems and human health.
