This chapter begins with a brief review of descriptions and definitions of mystical-type experiences and the historical connection between classic hallucinogens and mystical experiences. The chapter then explores the empirical literature on experiences with classic hallucinogens in which claims about mystical or religious experiences have been made. A psychometrically validated questionnaire is...

Lysergic acid diethylamide (LSD), is a classical hallucinogen, discovered accidentally in the middle century. It is a psychedelic drug used to treat drug abuse as it shows limited efficacy, leaving severe and persistent effects in treated patients. Preliminary studies in animals and clinical trials suggest that lysergic acid diethylamide may have anti-depressive, anxiolytic, hallucinogenic and...
The present study sought to extend compulsive sexual behavior (CSB) and mindfulness research by testing whether dispositional mindfulness negatively related to CSB among men with substance use disorders (SUD) through experiential avoidance. Dispositional mindfulness is believed to decrease experiential avoidance, a correlate of CSB. We therefore hypothesized that dispositional mindfulness would...
Article AbstractBecause this piece does not have an abstract, we have provided for your benefit the first 3 sentences of the full text.To the Editor: Dr Bartoli and colleagues suggest that the dissociative and antidepressant effects of ketamine are two sides of the same coin or, to use a different metaphor, that they go hand in hand. This is hardly surprising. The efficacy and adverse effects...
Salvinorin A (SalA) is a plant metabolite that agonizes the human kappa-opioid receptor (κ-OR) with high affinity and high selectivity over mu- and delta-opioid receptors. Its therapeutic potential has stimulated extensive semisynthetic studies and total synthesis campaigns. However, structural modification of SalA has been complicated by its instability, and efficient total synthesis has been...
The classical psychedelic drugs, including psilocybin, lysergic acid diethylamide and mescaline, were used extensively in psychiatry before they were placed in Schedule I of the UN Convention on Drugs in 1967. Experimentation and clinical trials undertaken prior to legal sanction suggest that they are not helpful for those with established psychotic disorders and should be avoided in those...
The bed nucleus of the stria terminals (BNST) is a subcortical structure involved in anticipatory and sustained reactivity to threat and is thus essential to the understanding of anxiety and stress responses. Although chronic stress and anxiety represent a hallmark of post-traumatic stress disorder (PTSD), to date, few studies have examined the functional connectivity of the BNST in PTSD. Here,...
Dissociative phenomena are common among psychiatric patients; the presence of these symptoms can worsen the prognosis, increasing the severity of their clinical conditions and exposing them to increased risk of suicidal behavior. Personality disorders as long duration stressful experiences may support the development of dissociative phenomena. In 933 psychiatric outpatients consecutively...
We used the psychotomimetic phencyclidine (PCP) to investigate the relationships among cognitive behavior, coordinated neural network function, and information processing within the hippocampus place cell system. We report in rats that PCP (5 mg/kg, i.p.) impairs a well learned, hippocampus-dependent place avoidance behavior in rats that requires cognitive control even when PCP is injected...
Methylenedioxymethamphetamine (MDMA, ecstasy) is used recreationally and frequently leads to sympathomimetic toxicity. MDMA produces cardiovascular and subjective stimulant effects that were shown to partially depend on the norepinephrine transporter (NET)-mediated release of norepinephrine and stimulation of α 1 -adrenergic receptors. Genetic variants, such as single-nucleotide polymorphisms...
