hallucinogen

 [hah-loo´sĭ-no-jen″]
a chemical agent capable of producing hallucinations. adj., adj hallucinogen´ic. Drugs that have hallucinogenic properties include lsd, mescaline, and psilocybin. Certain mushrooms, seeds, and cactus buttons (such as peyote) are also hallucinogenic. The experiences brought about by the use of hallucinogens involve a more acute “awareness” of one's environment and a distorted response to visual, auditory, and tactile stimuli. They can also cause a person to exhibit behavior symptomatic of a psychotic state of mind. Indiscriminate use of these compounds can bring on psychosis and may result in permanent brain damage. drug abuse with hallucinogens has led to the regulation of their distribution by the Food and Drug Administration.

A Hypothesis of the Mechanisms Underlying Visual Distortions Caused by Psychedelic Drugs. Available at http://www.erowid.org/archive/rhodium/pharmacology/visualdistortions.html
Based on anecdotal evidence--such as hundreds of psychedelic drug experience self-reports available online (Erowid 2010)--our initial work hypothesis held that there should be detectable differences in life meaningfulness and coping characteristics between autognostic psychonauts, users of other drugs for other purposes, and drug nonusers.
Youth flocked to San Francisco to be part of the hippie scene, to dance, to listen to rock and roll, to protest the Vietnam war, and to take drugs, particularly marijuana, hashish, and psychedelic drugs. After they arrived, they took whatever drugs were popular or available: LSD (lysergic acid diethylamide), both real and bogus, psilocybin--"magic mushrooms" that were more often than not grocery-store mushrooms laced with LSD--and the latest creations of several world-class psychedelic chemists in the San Francisco Bay Area.
One of the most respected online drug information sources, particularly among psychedelic drug users, is Erowid: this site is the first port of call for most psychonauts before they embark on an adventure with a new substance (http://www.erowid.org).
Folklore and anecdotal evidence have long suggested that psychedelic drugs such as cannabis and LSD may enhance creativity, and there has been some experimental support for this (Krippner 1977), or at least support for such drugs increasing the perception that one is being creative (Krippner 1985, 1968).
Abstract--This article investigates the influence of perception that is altered by psychedelic drugs on processes of creativity through a case study of the work of well-known comic artist Robert Crumb.
The former Never Mind the Buzzcocks presenter, 39, danced "like a lunatic" while high on the psychedelic drug ayahuasca last month, prompting guffawing from his "healers", who were overseeing the spiritual experience.
The Never Mind the Buzzcocks comedian drank psychedelic drug ayahuasca to help him let go of his shame around sex and nudity.
The jury was shown videos taken by the defendant as her condition worsened - and possibly after she had died - after she had taken a "large dose" of the psychedelic drug on the afternoon of September 10.
Her ex-boyfriend and rapper Ceon Broughton gave her a dose of a psychedelic drug and filmed her as she died, asking for help.
Smaller amounts of LSD, ketamine, cannabis and psychedelic drug 4-HO-MET were also discovered at his Beech Court flat.
In his fascinating book How to Change Your Mind, bestselling author Michael Pollan (The Omnivore's Dilemma, Cooked) discusses the recent psychedelic drug resurgence.
