The Argument

Major psychedelic drugs include LSD, DMT, mescaline, and psilocybin. These drugs primarily act on serotonin receptors in the brain. Serotonin is an important neurotransmitter which affects many areas of brain function, including cognition, learning, and memory, but is most commonly associated with rewarding feelings of happiness and contentment. By acting on serotonin receptors and thus influencing the complex neurochemistry of serotonin, psychedelic drugs can trigger a myriad of changes to perception and consciousness, from trance-like states to flashbacks to psychotic episodes.
