Caffeine, cocaine, and painkillers detected in sharks from The Bahamas

This classifies Cocaine Shark as a documentary https://en.wikipedia.org/wiki/Cocaine_Shark

  • So much potential in that franchise. Cocaine moose, cocaine snake (or Snakes on Cocaine, which could have the line “I want these mother f’ing snakes off mother f’ing cocaine!”), cocaine lion, cocaine hippo, cocaine alligator…

    • Meh, i think branching out to different animals is a mistake. They could have evolved beyond comedy to drama by instead putting the bear on meth in the sequel. Follow the bear through its downward spiral losing its teeth and eventually hitting bottom drinking its own urine to stay high. The redemption ark could be an unlikely friendship formed with one of the campers it mauled in the first movie sparked by the bear sobering up and doing the apology tour.

Not surprising. A lot of these substances get metabolized, or just diluted by water and filtered out without being like, magically deconstructed and turned into all CO2 and H2O and N2. So a lot of wacky chemical compounds humans tend to consume tend to get detected wherever humans gather and discharge bodily fluids that eventually reach the ocean. This does not immediately indicate that e.g. evil corporations are dumping toxic wastes, forever plastics pieces are leaching out scary additives, etc.

The measured concentrations are on the order of 1-20 ng/mL in blood. Cmax in humans when taking those drugs are about 100-1000x higher.

I wouldn't put too much weight on the finding that those with detections had different urea/lactate etc. There might be something underlying explaining both drug and physiology, like age.

Could still be bad to have chronic exposure at such low levels - also fish physiology is different.

I wonder how much of this is just that our tests are getting more sensitive.

  • Exactly, the detection itself doesn't mean anything. Is the dose relevant? If not, then not. And the dose likely isn't relevant.

    • Agreed. When you zoom in, even the normal life stuff can give you concern. I showed my kids what creatures live on their and others' bodies. You have millions of microscopic arachnids called Demodex mites living in your hair follicles and sebaceous glands, particularly on your face. My wife gave me an evil look as I showed my children this fact in online vids and pics. Granted these are symbiotic/parasitic relationships of life, but still, the closer you look, the more you see!

Does that make for more aggressive sharks in the waters with unexplained behaviors?

Is caffeine really that bad?

After the "plastic glove" smoking gun the other day, I wonder if this is another instance of lab contamination making it into the results.
