If that is not one good argument to start producing cocaine locally, then I don't know! Save the fish.

Could this not have been simply an instinct to find cleaner waters? I'm surprised they didn't add another control group which injected something unpleasant that could be naturally found in an area, but would be undesirable - ammonia, some sort of acid, or something along those lines.

Shine on you crazy salmon

And just like that, smoked Salmon became popular again :) BTW, did you knew municipalities can easily measure fluctuations in drug usage by testing the sewage water? In fact, sometimes they can see clear differences between different parts of the city.

We’re looking at you, Vancouver.

Cocaine bear, cocaine shark, cocaine… salmon?

I learned recently about “Vin Mariani” a wine from the 1860s that was fortified with coca leaves and contained 6mg per liquid ounce of the wine; except for the bottles sold in USA where it was 7.2mg per ounce, because there were other patent medicines that had cocaine in them and the manufacturer added a bit more to be competitive in the market. The Pope of the time loved the stuff and awarded the company a Vatican medal for it.

Next up: smackhead whales, dolphins on crack, and manatees hitting the bong.

I wonder about the root cause. Can it be explained as: (1) Stimulant helps the fish to swim more distance? (2) Inhibition is lowered so the fish is more willing to explore?

Good news everyone! If you give a fish a stimulant, it swims more!

How does one get a job as a "let's give cocaine to this animal and see what happens" scientist?

1) Reading the original article as far as I understand, indicates that the dose given the fish is 1000x than is seen in the wild. 2) From a public policy standpoint, OMG, this more than useless. Cocaine is already illegal everywhere.

Weird, it usually keeps me pretty close to a club toilet.

Believe it or not, I am sitting here in botoga in a cafe and drinking coca tea...

Carter Vail was right. Cocaine was invented by salmon - I bet you didn't know that. https://www.youtube.com/watch?v=GX0tVk5T6zc

"Cocaine makes me feel like a new salmon. And he wants some too!"
