Some Rivers Are So Drug-Polluted, Their Eels Get High on Cocaine

Illegal drug residues in the water could be affecting native fish.

Critically endangered eels hyped up on cocaine could have trouble making a 3,700-mile trip to mate and reproduce—new research warns.

And while societies have long grappled with ways to cope with the use of illicit drugs, less understood are the downstream effects these drugs might have on other species after they enter the aquatic environment through wastewater.

So, in the name of research, scientists pushed cocaine on European eels in labs for 50 days in a row, in an effort to monitor the effects of the experience on the fish.

The eels are vulnerable to trace concentrations of cocaine, particularly in their early lives, according to the researchers of a study published in Science of the Total Environment.
