The hallucinogen d-lysergic acid diethylamide (d-LSD) evokes dramatic somatic and psychological effects. In order to analyze the neural activation induced by this unique psychoactive drug, we tested the hypothesis that expression of the immediate-early gene product c-Fos is induced in specific regions of the rat forebrain by a relatively low, behaviorally active, dose of d-LSD (0.16 mg/kg,...
This article aims to explore, through established scientific research and documented accounts of personal experience, the similarities between religious mystical experiences and some effects of D-lysergic diethylamide or LSD. LSD predominantly works upon the serotonergic (serotonin-using neurons) diffuse neuromodulatory system, which projects its axons to virtually all areas of the brain...
Lysergic acid amides were prepared from (R,R)-(-)-, (S,S)-(+)-, and cis-2,4-dimethyl azetidine. The dimethylazetidine moiety is considered here to be a rigid analogue of diethylamine, and thus, the target compounds are all conformationally constrained analogues of the potent hallucinogenic agent, N,N-diethyllysergamide, LSD-25. Pharmacological evaluation showed that...
In this paper, the authors call into question the idea of moral panic and delineate the rudiments of an alternate model of deviance construction and moral public discourse, using LSD prohibition as a working example. In developing their model, the authors draw on research on people in disasters and collective behavior. In keeping with these traditions, they argue that, when faced with emergent...
Hallucinogenic drugs such as lysergic acid diethylamide (LSD) have profound effects on humans including hallucinations and detachment from reality. These remarkable behavioral effects have many similarities to the debilitating symptoms of neuropsychiatric disorders such as schizophrenia. The effects of hallucinogens are thought to be mediated by serotonin receptor activation; however, how these...
The current study uses a qualitative methodology to investigate socio-cultural and psychological aspects involved in the use of LSD and comparable psychedelic substances. To date, 26 narrative interviews have been conducted with 12 female and 14 male users aged 19 to 53 years. The resulting data were subjected to content analysis in several thematic areas. Subjective reports of LSD use and...
The use of the word "hallucinogens" to classify LSD and other drugs is common-sensical, vague and sometimes confusing. The classification scheme of Jean Delay, first suggested in 1959, is more clinically precise. In this scheme hallucinogens are classified as psychodysleptics (psycho-dysleptiques) because of their characteristic psychological effects: disturbance of mental activity and the...
The trace amine para-tyramine is structurally and functionally related to the amphetamines and the biogenic amine neurotransmitters. It is currently thought that the biological activities elicited by trace amines such as p-tyramine and the psychostimulant amphetamines are manifestations of their ability to inhibit the clearance of extracellular transmitter and/or stimulate the efflux of...
Although psychedelics can induce "cosmic" consciousness through severe distortions of time and space perceptions, little attention has been given to examination of this psychopharmacological property. With the hope of providing an impetus to further research in this area, a case of cosmic perception under the influence of LSD is reported which included the apparent movement of consciousness to...
The metabolism of lysergic acid diethylamide (LSD) to 2-oxo-3-hydroxy lysergic acid diethylamide (O-H-LSD) was investigated in liver microsomes and cyropreserved hepatocytes from humans. Previous studies have demonstrated that O-H-LSD is present in human urine at concentrations 16-43 times greater than LSD, the parent compound. Additionally, these studies have determined that O-H-LSD is not...
