However, the relationship between marijuana use and perinatal complications in live births is uncertain. Objective—Our aim was to examine if [...]

Johnson Journal of Psychopharmacology, 2018, 1 –14 https://doi.org/10.1177/0269881118780 Abstract Background : Recent pilot trials suggest feasibility and potential efficacy of psychedelic-facilitated addiction treatment interventions. Fifteen participants completed a psilocybin-facilitated smoking cessation pilot study between 2009 and 2015. Aims : The aims of this study were as follows: (1) to identify perceived mechanisms of change leading to smoking cessation in the pilot study; (2) to identify key themes in participant experiences and long-term outcomes to better understand the therapeutic process. Methods : Participants were [...]

Recently, after a long [...]

Despite the fact that a number of registered medicines have been developed on the basis of purified cannabis components, there is a rapid increasing acceptance and use of cannabis in its herbal form. Licensed producers of high quality cannabis plants now operate in various countries including The Netherlands, Canada, Israel, and Australia, and in many US states. The legal availability of [...]
Lire la suiteDeveloping Guidelines and Competencies for the Training of Psychedelic Therapists Janis Phelps Journal of Humanistic Psychology, 2017, 1–38 DOI: 10.1177/0022167817711304 Abstract Research since the 1950s has shown that psychedelic-assisted psychotherapy has had significant positive effects in reductions of specific clinical symptoms and increases in quality of life as measured on a variety of indices. The intensity of focus on evidence-based outcomes, however, has resulted in a paucity of active discussions and research on the core competencies of the therapists themselves. The context of the history of psychedelic research reveals how this neglect of therapist variables occurred. With current discussions of Phase 3 and expanded access [...]

Med-CannabisUSA will address the many controversies surrounding cannabis-based medicines. Strong public and patient demand has led to the decision to allow cannabis products for medical use all over the world. There is a rapidly-growing basic-science and clinical research literature providing insight into potential use of cannabis products for chronic pain, cancer management, and many other medical areas. Growing concerns and controversies focusing on overly-optimistic therapeutic claims and potential harms parallel recent expanded access [...]
Lire la suiteCannabinoid CB1 and CB2 Receptor Signaling and Bias Mikkel Soes Ibsen, Mark Connor, Michelle Glass Cannabis and Cannabinoid Research, 2017, Volume 2.1, 48-60 https://doi.org/10.1089/can.2016.0037 Abstract An agonist that acts through a single receptor can activate numerous signaling pathways. Recent studies have suggested that different ligands can differentially activate these pathways by stabilizing a limited range of receptor conformations, which in turn preferentially drive different downstream signaling cascades. This concept, termed “biased signaling” represents an exciting therapeutic opportunity to target specific pathways that elicit only desired effects, while avoiding undesired effects mediated by different signaling cascades. The cannabinoid receptors CB1 and CB2 each activate multiple pathways, [...]
