FURTHER STUDIES ON THE MODE OF ACTION OF PSYCHOTOMIMETIC DRUGS: ANTAGONISM OF THE EXCITATORY ACTIONS OF 5‐HYDROXYTRYPTAMINE BY METHYLATED DERIVATIVES OF TRYPTAMINE

British Journal of Pharmacology March 1, 1974 Philip Bradley, Ian Briggs 54 citations

The actions of 5‐methoxytryptamine (5‐MeOT), N,N ‐dimethyltryptamine (DMT), 5‐hydroxy‐ N,N ‐dimethyltryptamine (bufotenine, 5‐HODMT) and 5‐methoxy‐ N,N ‐dimethyltryptamine (5‐MeODMT), and their interactions with 5‐hydroxytryptamine (5‐HT), acetylcholine, (–)‐noradrenaline, and glutamate were studied by microiontophoresis on single neurones in the brain stem of rats anaesthetized with urethane...

Psychedelic Drugs in Correctional Treatment

Crime & Delinquency July 1, 1972 D F Duncan 1 citation

Psychedelic drugs have been used for individual psychotherapy in prison settings. This paper outlines two studies that explore the use of psychedelic drugs in correction. In 1961 Timothy Leary and Walter Houston Clark administered psilocybin to thirty-three prisoners at the Massachusetts Correctional Insti tution. This program seemed to have positive effects on the inmate-subjects. William H....

Drug use and hypnotic susceptibility

International Journal of Clinical and Experimental Hypnosis 1972 David Whitman van Nuys 4 citations

Abstract 47 undergraduate male volunteers were asked 2 questions relating to their use of marijuana and/or psychedelic drugs (e.g., LSD, mescaline, psilocybin) and were administered the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A). The HGSHS:A scores of Ss who had, at some time, taken any of these drugs averaged 2 points higher than scores of Ss who had not. Further research...

II. The Effects of Some Hallucinogens on Aggressiveness of Mice and Rats

Pharmacology 1972 Wojciech Kostowski, W Rewerski, T Piechocki 28 citations

The action of JB-336, psilocybin, ibogaine and bufotenine on the aggressiveness os isolated mice, as well as the muricide reaction of rats, was investigated. All drugs evoked a substantial decrease in aggressiveness, but this effect was dependent on isolation time, time after injection and the type of test used.

DOET(2,5-Dimethoxy-4-Ethylamphetamine), a New Psychotropic Drug

Archives of General Psychiatry 1971 Solomon H. Snyder 30 citations

DOET (2,5-dimethoxy-4-ethylamphetamine) is a new psychotropic agent which chemically resembles mescaline and amphetamine. It is essentially the ethyl homologue of DOM (2,5-dimethoxy-4-methylamphetamine), a psychotomimetic drug widely used by hippie populations and designated "STP." DOET was administered to normal male subjects in doses ranging from 0.75 to 4 mg and contrasted with effects of a...

Microcrystalloptic tests for lysergic acid diethylamide and other hallucinogens

Journal of Pharmacy and Pharmacology November 1, 1970 K. Genest, Lorna J. Lowry

Abstract Microcrystallopic tests for LSD, NN-diethyltryptamine, NN-dimethyltryptamine, bufotenine, psilocin, psilocybin and STP are described. The tests are recommended in conjunction with other analytical techniques if applied for the forensic identification of hallucingens.

The experimental use of psychedelic (LSD) psychotherapy

JAMA June 15, 1970 W. N. Pahnke 41 citations

The history of research with psychedelic drugs has produced a variety of methods for their use and conflicting claims about results. First came the wave of excitement among experimentalists in the 1950s when it was claimed that lysergic acid diethylamide (LSD) could produce a model psychosis which might be useful in understanding schizophrenia. While this promise was fading, enthusiastic...

Flashbacks: Recurrent Intrusive Images After the Use of LSD

American Journal of Psychiatry October 1, 1969 Mardi J. Horowitz 125 citations

Flashbacks are returns of imagery for extended periods after the immediate effect of hallucinogens has worn off. The most symptomatic form is recurrent intrusions of the same frightening image into awareness, without volitional control. The author compares flashbacks with other clinical phenomena; he believes that psychotherapy is helpful, especially if there is a focus on the traumatic and...

A study of the role of noradrenaline in behavioural changes produced in the rat by psychotomimetic drugs

British Journal of Pharmacology February 1, 1969 Michael F. Sugrue 40 citations

LSD‐25, psilocybin and JB‐329 reduced the noradrenaline content of the rat hypothalamus. All three drugs affected the acquisition of a conditioned avoidance response, LSD‐25 and psilocybin retarding and JB‐329 enhancing the acquisition. With the exception of JB‐329, doses affecting the acquisition of a conditioned avoidance response were lower than those required to decide hypothalamic...

DOM (STP), a New Hallucinogenic Drug, and DOET: Effects in Normal Subjects

American Journal of Psychiatry September 1, 1968 Solomon H. Snyder, Louis A. Faillace, Herbert Weingartner 77 citations

DOM, a hallucinogen related to mescaline and amphetamine and designated "STP" by hippies, along with DOET, the ethyl homologue of DOM, were given in small doses to normal subjects in a double-blind study. Both drugs increased self-awareness and produced mild euphoria but no hallucinogenic or psychotomimetic effects. The two drugs "freed up" subjects' word associations without impairing memory...
