Scientists drugged fish - and couldn't believe what happened to them

Researchers in Canada exposed aggressive fish to psilocybin, the active ingredient in hallucinogenic mushrooms, and discovered a change in their behavior: fewer attacks and more calm. The study was published in the journal Frontiers in Behavioral Neuroscience. The researchers emphasize that no direct conclusions can be drawn for humans.

Researchers from Acadia University and the University of British Columbia exposed aggressive mangrove rivulus fish to psilocybin, the active ingredient in hallucinogenic mushrooms. The experiment showed a change in the fish's behavior: fewer attacks, less movement, and more calm. The study was published in the journal Frontiers in Behavioral Neuroscience. The researchers emphasize that this was a short experiment on fish, and no direct conclusions can be drawn regarding humans, and there is no evidence that the fish experienced hallucinations. The headline creates a curiosity gap about the result.
