Cannabidiol (CBD) is an exogenous phytocannabinoid with therapeutic potential for individuals with anxiety, poor sleep, and cognitive deficits, as well as populations with endocannabinoid deficiencies, such as those who suffer from FXS. The objective of this study was to provide a brief narrative review of recent literature on endocannabinoids and FXS and [...]

Psilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer : A randomized double-blind trial GRIFFITHS R.R., JOHNSON M.W., CARDUCCI M.A., UMBRICHT A., RICHARDS W.A., RICHARDS B.D., COSIMANO M.P., KLINEDINST M.A. Journal of Psychopharmacology, 2016, 30, 12, 1181–1197. DOI: 10.1177/0269881116675513       jop.sagepub.com   Abstract Cancer patients often develop chronic, clinically significant symptoms of depression and anxiety. Previous studies suggest that psilocybin may decrease depression and anxiety in cancer patients. The effects of psilocybin were studied in 51 cancer patients with life-threatening diagnoses and symptoms of depression and/or anxiety. This randomized, double-blind, cross-over trial investigated the effects of a very low (placebo-like) dose [...]

Increased nature relatedness and decreased authoritarian political views after psilocybin for treatment-resistant depression, Taylor Lyons, Robin L. Carhart-Harris, 2018

Increased nature relatedness and decreased authoritarian political views after psilocybin for treatment-resistant depression LYONS T., CARHART-HARRIS R.L. Journal of Psychopharmacology, 2018, 32, 7, 811-819. Doi : 10.1177/0269881117748902   journals.sagepub.com/home/jop   Abstract Rationale : Previous research suggests that classical psychedelic compounds can induce lasting changes in personality traits, attitudes and beliefs in both healthy subjects and patient populations. Aim : Here we sought to investigate the effects of psilocybin on nature relatedness and libertarian authoritarian political perspective in patients with treatment-resistant depression (TRD). Methods : This open-label pilot study with a mixed-model design studied the effects of psilocybin on measures of nature relatedness and libertarian– authoritarian political perspective in patients with [...]

Effects of psilocybin therapy on personnality structure, D. Erritzoe et al., 2018

Effects of psilocybin therapy on personnality structure ERRITZOE D., ROSEMAN L., NOUR M.M., MacLEAN K., KAELEN M., NUTT D.J., CARHART-HARRIS R.L. Acta Psychiatrica Scandinavica, 2018, 1-11. DOI : 10.1111/acps.12904 .   Objective : To explore whether psilocybin with psychological support modulates personality parameters in patients suffering from treatment-resistant depression (TRD). Method : Twenty patients with moderate or severe, unipolar, TRD received oral psilocybin (10 and 25 mg, one week apart) in a supportive setting. Personality was assessed at baseline and at 3-month follow-up using the Revised NEO Personality Inventory (NEO-PI-R), the subjective psilocybin experience with Altered State of Consciousness (ASC) scale, and depressive symptoms with QIDS-SR16.

Quality of Acute Psychedelic Experience Predicts Therapeutic Efficacy of Psilocybin for Treatment-Resistant Depression, Leor Roseman, David J. Nutt, Robin L. Carhart-Harris, 2018

Quality of Acute Psychedelic Experience Predicts Therapeutic Efficacy of Psilocybin for Treatment-Resistant Depression Leor Roseman, David J. Nutt, Robin L. Carhart-Harris Psychedelic Research Group, Department of Medicine, Imperial College London, London, United Kingdom Frontiers in Pharmacology, 2018, 8, article 974. Doi : 10.3389/fphar.2017.00974 .   Introduction : It is a basic principle of the “psychedelic” treatment model that the quality of the acute experience mediates long-term improvements in mental health. In the present paper we sought to test this using data from a clinical trial assessing psilocybin for treatment-resistant depression (TRD). In line with previous reports, we hypothesized that the occurrence and magnitude of Oceanic Boundlessness (OBN) [...]

Relapse is the main cause of concern when treating addiction. It could manifest after a long period of abstinence. Previous studies showed that there is a strong connection between sleep impairment and relapse. Also, it has been reported that cannabidiol might be a potential treatment for drug craving and relapse. [...]
