Psychedelics, such as psilocybin and LSD, interact as serotonin agonists, interacting predominantly with serotonin receptors in the brain (Jaster and González-Maeso, 2023).

Modulating serotonin receptors triggers a series of consequences, ultimately leading to the induction of modified states of consciousness
