Psychedelic therapy (or psychedelic-assisted therapy) is the proposed use of psychedelic drugs to treat mental disorders. [60] As of 2021, psychedelic drugs are controlled substances in most countries and psychedelic therapy is not legally available outside clinical trials, with some exceptions.
Furthermore, retrospective studies involving users of illicit drugs as voluntary subjects were conducted, allowing data to be collected on how psychedelics affect the human brain while simultaneously sidestepping bureaucratic difficulties associated with providing illegal substances to subjects.

Psychoactive drugs operate by temporarily affecting a person's neurochemistry, which in turn causes changes in a person's mood, cognition, perception and behavior. There are many ways in which psychoactive drugs can affect the brain. Each drug has a specific action on one or more neurotransmitter or neuroreceptor in the brain.
Additionally, scientists discovered that participants who were heavy cannabis users also had reduced brain activity in certain areas of the brain, including the dorsolateral prefrontal cortex ...
No clear connection has been made between psychedelic drugs and organic brain damage. However, hallucinogen persisting perception disorder (HPPD) is a diagnosed condition wherein certain visual effects of drugs persist for a long time, sometimes permanently, [ 61 ] although the underlying cause and pathology remains unclear.
Psychedelics, including psilocybin, have been shown to affect different clusters of brain regions known as the "theory of mind network" (ToMN) and the default mode network (DMN).

The effects of psychedelics on neuroplasticity appear to be dependent on serotonin 5-HT 2A receptor activation, as they are abolished in 5-HT 2A receptor knockout mice. [7] Non-hallucinogenic serotonin 5-HT 2A receptor agonists, like tabernanthalog and lisuride, have also been found to increase neuroplasticity, and to a magnitude comparable to ...
