Dark Classics in Chemical Neuroscience: 3,4-Methylenedioxymethamphetamine

ACS Chemical Neuroscience July 12, 2018 Lee E. Dunlap, Anne M. Andrews, David E. Olson 105 citations

Better known as "ecstasy", 3,4-methylenedioxymethamphetamine (MDMA) is a small molecule that has played a prominent role in defining the ethos of today's teenagers and young adults, much like lysergic acid diethylamide (LSD) did in the 1960s. Though MDMA possesses structural similarities to compounds like amphetamine and mescaline, it produces subjective effects that are unlike any of the...

Psychedelics and Personality

ACS Chemical Neuroscience June 4, 2018 Marc Aixalà, Rafael G. Dos Santos, Jaime E. C. Hallak et al. 14 citations

In the past decade, an increasing number of clinical trials are reporting evidence that psychedelics or serotonergic hallucinogens (such as lysergic acid diethylamide, psilocybin, and ayahuasca/dimethyltryptamine) could be effective in the treatment of mood, anxiety, and substance use disorders. The mechanisms responsible for these effects are not fully understood but seem to involve changes in...

Using in vitro norepinephrine transporter (NET) inhibition and 5‐HT 2 receptor binding data to predict psychoactive doses of novel psychoactive substances in humans

The FASEB Journal April 1, 2018 Matthias E. Liechti, Dino Luethi

Objective Novel psychoactive substances (NPS) or “bath salts” are increasingly sold over the Internet and used as substitutes for classic recreational substances. Previous studies showed that classic amphetamine‐type stimulants most potently act on the norepinephrine (NE) compared to the dopamine (DA) and serotonin (5‐HT) system and NE activation correlated with the subjective effects across...

Synesthetic hallucinations induced by psychedelic drugs in a congenitally blind man.

Consciousness and Cognition April 1, 2018 Sara Dell'Erba, David J Brown, Michael J. Proulx 11 citations

This case report offers rare insights into crossmodal responses to psychedelic drug use in a congenitally blind (CB) individual as a form of synthetic synesthesia. BP's personal experience provides us with a unique report on the psychological and sensory alterations induced by hallucinogenic drugs, including an account of the absence of visual hallucinations, and a compelling look at the...

Serotonergic hallucinogens in the treatment of anxiety and depression in patients suffering from a life-threatening disease: A systematic review.

Progress in Neuro-Psychopharmacology and Biological Psychiatry February 2, 2018 Simon Reiche, Leo Hermle, Stefan Gutwinski et al. 125 citations

Anxiety and depression are some of the most common psychiatric symptoms of patients suffering with life-threatening diseases, often associated with a low quality of life and a poor overall prognosis. 5-HT2A-receptor agonists (serotonergic hallucinogens, 'psychedelics') like lysergic acid diethylamide (LSD) and psilocybin were first investigated as therapeutic agents in the 1960s. Recently,...

The Experience Elicited by Hallucinogens Presents the Highest Similarity to Dreaming within a Large Database of Psychoactive Substance Reports

Frontiers in Neuroscience January 22, 2018 Camila Sanz, Federico Zamberlán, Earth Erowid et al. 112 citations

Ever since the modern rediscovery of psychedelic substances by Western society, several authors have independently proposed that their effects bear a high resemblance to the dreams and dreamlike experiences occurring naturally during the sleep-wake cycle. Recent studies in humans have provided neurophysiological evidence supporting this hypothesis. However, a rigorous comparative analysis of...

Serotonergic Hallucinogen-Induced Visual Perceptual Alterations.

Current Topics in Behavioral Neurosciences 2018 Michael Kometer, Franz X. Vollenweider

Serotonergic hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and N,N-dimethyltryptamine (DMT), are famous for their capacity to temporally and profoundly alter an individual's visual experiences. These visual alterations show consistent attributes despite large inter- and intra-individual variances. Many reports document a common perception of colors as more saturated, with...

A Review of Hallucinogen Persisting Perception Disorder (HPPD) and an Exploratory Study of Subjects Claiming Symptoms of HPPD.

Current Topics in Behavioral Neurosciences 2018 John H. Halpern, Arturo G Lerner, Torsten Passie

Hallucinogen persisting perception disorder (HPPD) is rarely encountered in clinical settings. It is described as a re-experiencing of some perceptual distortions induced while intoxicated and suggested to subsequently cause functional impairment or anxiety. Two forms exist: Type 1, which are brief "flashbacks," and Type 2 claimed to be chronic, waxing, and waning over months to years. A review...

Advances and challenges in neuroimaging studies on the effects of serotonergic hallucinogens: Contributions of the resting brain.

Progress in Brain Research 2018 Felix Müller, Matthias E. Liechti, Undine E. Lang et al. 32 citations

The effects of hallucinogenic drugs on the human brain have been studied since the earliest days of neuroimaging in the 1990s. However, approaches are often hard to compare and results are heterogeneous. In this chapter, we summarize studies investigating the effects of hallucinogens on the resting brain, with a special emphasis on replicability and limitations. In previous studies,...

The “Endless Trip” among the NPS Users: Psychopathology and Psychopharmacology in the Hallucinogen-Persisting Perception Disorder. A Systematic Review

Frontiers in Psychiatry November 20, 2017 Laura Orsolini, Gabriele Duccio Papanti, Domenico de Berardis et al. 99 citations

Hallucinogen-persisting perception disorder (HPPD) is a syndrome characterized by prolonged or reoccurring perceptual symptoms, reminiscent of acute hallucinogen effects. HPPD was associated with a broader range of LSD (lysergic acid diethylamide)-like substances, cannabis, methylenedioxymethamphetamine (MDMA), psilocybin, mescaline, and psychostimulants. The recent emergence of novel...
