Key Magic Mushroom Ingredient Increases Laziness and Reduces Aggression

Canadian researchers found that low-dose psilocybin calmed aggressive mangrove rivulus fish during social encounters.

The fish showed less movement and fewer attack-like behaviors, but they still maintained basic social interaction.

The study suggests psilocybin may reduce escalated aggression without broadly suppressing social behavior.

This could provide a new vertebrate model for studying how psilocybin affects conflict and mood-related behaviors.
