hallucinogens

Hallucinogen New Psychoactive Substances

"Hallucinogen NPS are a diverse group of substances that alter an individual’s awareness of their surroundings, as well as their thought processes and perception, which can lead to substantial distortions of reality. They can be divided into two main types: dissociatives, which induce euphoria alongside a feeling of weightlessness and detachment from the body; and classic hallucinogens, which produce altered perception,15 causing cognitive and visual disturbances and an altered state of consciousness.

Entheogens as Psychedelics

"Another peculiar effect of these drugs is a dramatic change in perception: it appears to the person as if the eyes (the 'doors of perception') have been cleansed and the person could see the world as new in all respects — 'as Adam may have seen it on the day of creation' as Aldous Huxley (1954, p. 17) pointed out in his popular and influential book. This new reality is perceived and interpreted by some individuals as manifestation of the true nature of their mind; hence, the term 'psychedelic' was suggested by Osmond (1957).
