Now, to be clear, scientists doubt the chemical buildups would affect humans, as people don't eat young, migrating chinook or sculpin (another small fish), and area drinking water comes from the Cascades -- pretty much as crisp and clean as you can get. That doesn't mean everyone should dismiss the chemically altered sea life, however.
“You have to wonder what it is doing to the fish,” Jim Meador, an environmental toxicologist told the paper.
In fact, fish migrating in estuaries of Puget Sound "die at twice the rate of fish elsewhere" and nobody knows how being hopped up on the entire contents of a medicine cabinet will affect the fish's ability to reproduce, migrate, and stave off disease. Additionally, no tests were done on organisms higher and lower in the food chain, so the broad impact has not been measured.
Suffice it to say: don't go swimming in estuaries near Puget Sound. Especially if you're a juvenile chinook salmon.
But if that's the case: holy shit! Those drugs enabled you to use a computer and read English!
