I know you’re the pro in these matters not me. OTOH, a reasonably effective dose of Fentanyl legitimately prescribed might be 25 micrograms per hour. Into a critter with ~5 liters of blood. So about 5 micrograms per liter is enough to have real physiological / psychological effects. ---

I’m imagining scientists in a lab looking for all sorts of contaminants in marine life; microplastics, carcinogens, petrochemicals, etc. One of them gets bored one day and looks for cocaine. Bam! Stop the presses! ---

So about 5 micrograms per liter is enough to have real physiological / psychological effects. This being the waters off Brazil, I’m surprised they didn’t test the sharks for fentanyl. The effects could more than balance out the cocaine, leading to mellow sharks that don’t bother anybody. ---

Let’s say you are in an e-boat that is obviously going to sink because the battery is too heavy. Do you go down with the ship and get electrocuted? Or, do you jump over by the sharks? What if you knew the sharks weren’t hopped up on cocaine…would that influence your decision? ---

I thought cocaine would be off the West coast of South America. Now we know the real crop planted in the deforested areas of the Amazon! ~VOW ---

More news (I hope this isn’t paywalled. I can’t tell because I have a subscription, so I’m not blocked.) The results are from the same team that found cocaine in Brazilian sharks. > **[Sharks are ingesting drugs in the Bahamas](https://www.sciencenews.org/article/cocaine-sharks-drugs-bahamas-eleuthera)** > > Nearly one third of sharks studied near the Bahamas’ Eleuthera Island were found to have caffeine, painkillers and other drugs in their bloodstreams. ---
