It’s a shame the fish had a better experience than the participants.
Last week, the American Chemical Society released the results of a 2011 study that analyzed water contamination levels measured before, during, and after a massive music festival in Taiwan. In news that shocked roughly 27 parents, the 600,000-plus crowd of young people who stormed that year’s Spring Scream fest introduced considerable amounts of MDMA (ecstasy), caffeine, and antibiotics into nearby rivers, along with a range of over-the-counter, prescription, and illegal drugs.
What was less obvious, according to the study (which was coordinated by multiple medical research facilities in Taiwan), was the intense impact an isolated, highly attended event could have on a region’s ecology. “To our knowledge, up to now no study has comprehensively dealt with Emerging Contaminants (ECs) residues and demonstrated the impact of tourism—especially of a time limited mass event,” the report stated.

Without comparison to what is considered a hazardous level the numbers are meaningless. You cant say there is an impact just based on the fact that there is a rise. You would have to show that it rose to a point where it is a meaningful amount.
Its also a fact that drugs that greatly affect humans can have no effect on other animals. The reverse is also true, though. For instance, caffeine is vastly more potent to many animals than it is to humans.
Don’t need to smoke that salmon 😉
