Reported effects of psychedelic use on those with low well-being given various emotional states and social contexts Natasha L. Mason, Patrick C. Dolder and Kim P.C. Kuypers Drug Science, Policy and Law, 2020, Volume 6, 1–11. Doi : 10.1177/2050324519900068 Abstract Background : It has been suggested that the outcome of the psychedelic experience is dependent on set and setting. While scientific research into the therapeutic potential of psychedelics is growing, it is clear that in clinical populations an optimal set and setting will not always be attainable. It was aimed to assess under which emotional and environmental circumstances psychedelic users use psychedelics, and the outcome [...]

Crippa, Jaime E.C. Hallak, Draulio B. de Araujo, Jordi Riba European Neuropsychopharmacology, 2015, 25, 483–492 http://dx.doi.org/10.1016/j.euroneuro.2015.01.008 Abstract Psychedelic agents have a long history of use by humans for their capacity to induce profound modifications in perception,emotion and cognitive processes. Despite increasing knowledge of the neural mechanisms involved in the acute effects of these drugs, the impact of sustained psychedelic use on the human brain remains largely unknown. Molecular pharmacology studies have shown that psychedelic 5-hydroxytryptamine (5HT)2A [...]
Lire la suiteMystical experiences occasioned by the hallucinogen psilocybin lead to increases in the personnality domain of openness Katherine A. MacLean, Matthew W. Johnson and Roland R. Griffiths Journal of Psychopharmacology, 2011, 25, (11), 1453-1461. doi: 10.1177/0269881111420188. Abstract A large body of evidence, including longitudinal analyses of personality change, suggests that core personality traits are predominantly stable after age 30. To our knowledge, no study has demonstrated changes in personality in healthy adults after an experimentally manipulated discrete event. Intriguingly, double-blind controlled studies have shown that the classic hallucinogen psilocybin occasions personally and spiritually significant mystical experiences that predict longterm changes in behaviors, attitudes and values. In [...]

We conducted a systematic review of studies assessing the effects [...]
Lire la suitePsychological variables implied in the therapeutic effect of ayahuasca : a contextual approach. Alba Franquesa, Alberto Sainz-Cort, Sam Gandy, Joaquim Soler, Miguel Ángel Alcázar-Córcoles, José Carlos Bouso Psychiatry Research, 2017 PII: S0165-1781(17)31377-X DOI: 10.1016/j.psychres.2018.04.012 Abstract Ayahuasca is a psychedelic decoction originating from Amazonia. The ayahuasca-induced introspective experience has been shown to have potential benefits in the treatment of several pathologies, to protect mental health and to improve neuropsychological functions and creativity, and boost mindfulness. The underlying psychological processes related to the use of ayahuasca in a psychotherapeutic context are not yet well described in the scientific literature, but there is some evidence to suggest that psychological [...]
