Sharks in Bahamas test positive for cocaine, caffeine: Study

(NewsNation) — Sharks in the Bahamas have tested positive for cocaine, caffeine and painkillers, a new study found, showing the impact of marine pollution.

Researchers analyzed blood samples from 85 sharks captured around one of the most remote islands in the Bahamas.

Of those sharks, 28 had drugs of some kind in their system.

The findings show how widespread pollution can spread, even to places seen as pristine, researchers say.

Caffeine was the most commonly found substance, but two sharks tested positive for cocaine, leading scientists to suspect they may have bitten into packets of the drug that fell into the water.

The sharks were captured near popular diving and cruise spots, suggesting that wastewater could be contributing to the results, along with increased wastewater from urban development and tourism.

It’s the first time caffeine has been found in sharks and the first time cocaine has been found in sharks in the Bahamas, though it has been found in sharks in other locations.

Researchers also found painkillers acetaminophen, the generic name for Tylenol, and diclofenac, which is sold under the brand names Voltaren, Cambia, Cataflam, Zipsor and Zorvolex.
