Cannabidiol Adverse Effects and Toxicity Marilyn A. Huestis, Renata Solimini, Simona Pichini, Roberta Pacifici, Jeremy Carlier and Francesco Paolo Busardò Current Neuropharmacology, 2019, 17, 974-989 Doi : 10.2174/1570159XI7666190603171901 Abstract : Background : Currently, there is a great interest in the potential medical use of cannabidiol (CBD), a non-intoxicating cannabinoid. Productive pharmacological research on CBD occurred in the 1970s and intensified recently with many discoveries about the endocannabinoid system. Multiple preclinical and clinical studies led to FDA-approval of Epidiolex®, a purified CBD medicine formulated for oral administration for the treatment of infantile refractory epileptic syndromes, by the US Food and Drug Administration in 2018. The World [...]

Treatment guidelines have unequivocally designated psychotherapy as a first line treatment for PTSD. Yet, even after psychotherapy, PTSD often remains a chronic illness, with high rates of psychiatric and medical comorbidity. Meanwhile, the search for and development of drugs with new mechanisms of action has stalled. Therefore, there is an urgent need to explore not [...]

Hutson Psychiatry Research, 2020, 284, 112749 Doi : 10.1016/j.psychres.2020.112749 A B S T R A C T The current meta-analysis examined the effects of psilocybin in combination with behavioral interventions on anxiety and depression in samples with elevated symptoms. Across four studies (one uncontrolled; three randomized, placebo-controlled; N = 117), within-group pre-post and pre-follow-up effects on anxiety and depression were large (Hedges’ gs=1.16 to 1.47) and statistically significant. Across three placebo-controlled studies, pre-post placebo-controlled effects were also [...]

Nicholas, Chi Wing Ng, Geetanjali Deole, Zhuofan Chen and Charles L. Raison Psychological Medicine, 2020, 1–12. doi : 10.1017/S003329172000389X Abstract Background. Scientific interest in the therapeutic effects of classical psychedelics has increased in the past two decades. The psychological effects of these substances outside the period of acute intoxication have not been fully characterized. This study aimed to: (1) quantify the effects of psilocybin, ayahuasca, and lysergic acid diethylamide (LSD) on psychological outcomes in the post-acute period; (2) test moderators of these effects; and (3) evaluate [...]
