Pending legislation, a cadre of trained psychotherapists are poised to apply their expertise for those who might benefit however, they are currently largely blocked from doing so. There are also ranks of competent psychedelically informed psychotherapists who might provide support to clients engaging with the medicines but are lacking guidelines to do so.\u0000 ‘Psychedelic-Supportive Psychotherapy’ is a proposed model which might be immediately implemented by qualified practitioners for working with clients adjacent to but not during a medicine experience without compromising ethical or legal risk. This model aimed at psychotherapists who are increasingly challenged to help clients already engaging with or considering psychedelics, draws from the current field of knowledge to respond to a moral imperative for practitioners to act in the service of client's best interests and expand access for diverse communities. It balances psychedelic harm reduction perspectives with support for the emotional, psychological, and spiritual gains to be had when clients use psychedelics outside of therapy and can process the experience within their therapy. The model of psychedelic-supportive psychotherapy,’ is transtheoretical, its core premise being centrality of the therapeutic relationship as a change agent even as the therapist is not physically present in the client's medicine journey. Here a foundational structure is presented along with criteria, parameters, and recommendations for practitioners in its application.","PeriodicalId":34732,"journal":{"name":"Journal of Psychedelic Studies","volume":" ","pages":""},"PeriodicalIF":4.5,"publicationDate":"2022-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43755724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial trials of psychedelic-assisted treatments have established feasibility and safety, generating calls for replications. Meanwhile, social and medical sciences have drawn criticism due to perceptions of replication failures and varying public trust in empiricism. Data suggest that researchers and the public frequently misunderstand some of the statistical issues associated with replication, potentially leading to unrealistic expectations of treatment effects. Promoting discourse on what constitutes sufficient replication is especially warranted considering the ongoing progression of multi-site phase II and III clinical trials. Here, we review recent and classic work on prediction intervals and power analysis to reveal that trials of psychedelic-assisted therapy that emphasize statistical significance will likely include failures to replicate, especially if sample sizes do not increase dramatically. The field and the public should expect some failed replication attempts based on sampling variability alone. Continued emphasis on statistical significance will require markedly larger samples than those used in clinical trials to date, necessitating substantially greater resources. An alternative approach focused on prediction intervals has distinct advantages. We focus on a recent trial of MDMA-assisted therapy for PTSD to show that, based on prediction intervals, reasonable replications are well within reach. A lack of attention to these statistical issues could unnecessarily prompt widespread dismissal of these therapies before the intervention receives adequate investigation and a fair assessment. In contrast, realistic expectations and appropriate planning could help ensure that these treatments receive the opportunity to help those most in need.","PeriodicalId":34732,"journal":{"name":"Journal of Psychedelic Studies","volume":" ","pages":""},"PeriodicalIF":4.5,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46221929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its use for indigenous religious purposes has appeared since pre-Columbian period in various localities of American continent. Practice is considered sacred in indigenous culture and suffered from trivialization of consumption due to influence of colonizers, which triggered subsequent industrialization of this complex for commercial purposes. Commercial snuff is essentially made from industrialized tobacco without addition of other medicinal plants and without therapeutic or spiritual purposes beyond its indiscriminate and inappropriate use, causing health risks. Therefore, this study aimed to make a review on snuff in Brazilian culture and a tour of a local community. In shamanism, plants are used as access vehicles to other religions of cosmos and its inhabitants, from where experts dialogue, bring songs, news, omens, and acquire new knowledge. The plants used in shamanic composition of snuff vary with the locality of indigenous villages in America and are essential ingredients of this interaction between humans and non-humans, a special mediator of intersubjective interactions. Several studies show the use and meaning of Erythroxylum coca used in different communities of the Amazon, besides Chacrona and Mariri, popular names of plants used in manufacture of Ayahuasca drink by doctrine Santo Daime. Because of this, it is essential to establish differences between recreational snuff and shamanic and their effects on body as well as studies on use of shamanic snuff should be directed according to their applications and plants employed by communities.","PeriodicalId":34732,"journal":{"name":"Journal of Psychedelic Studies","volume":"1 1","pages":""},"PeriodicalIF":4.5,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41714193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
