Individual Experiences in Four Cancer Patients Following Psilocybin-Assisted Psychotherapy Tara C. Malone, Sarah E. Mennenga, Jeffrey Guss, Samantha K. Podrebarac, Lindsey T. Owens, Anthony P. Bossis, Alexander B. Belser, Gabrielle Agin-Liebes, Michael P. Bogenschutz and Stephen Ross Frontiers in Pharmacology, 2018, 9, 256 doi: 10.3389/fphar.2018.00256 Abstract : A growing body of evidence shows that existential and spiritual well-being in cancer patients is associated with better medical outcomes, improved quality of life, and serves as a buffer against depression, hopelessness, and desire for hastened death. Historical and recent research suggests a role for psilocybin-assisted psychotherapy in treating cancer-related anxiety and depression. A double-blind controlled trial was performed, where 29 [...]

Vollenweider Proceedings of the National Academy of Sciences ,· January 2019 DOI: 10.1073/pnas.1815129116 Abstract : Psychedelics exert unique effects on human consciousness. The thalamic filter model suggests that core effects of psychedelics may result from gating deficits, based on a disintegration of information processing within cortico–striato–thalamo-cortical (CSTC) feedback loops. To test this hypothesis, we characterized changes in directed (effective) connectivity between selected CTSC regions after acute administration of lysergic acid diethylamide (LSD), and after pretreatment with Ketanserin (a selective serotonin [...]

Damian McNamara, CME, Laurie Barclay, MD Posted: 12/14/2018 Clinical Context The effects of cannabis in humans include euphoria, increased sensitivity to external experience, relaxation, and potential for addiction. Cannabidiol is a compound in the cannabis plant that lacks euphoric and addictive qualities and that may be useful to treat conditions including chronic pain, nausea, epilepsy, psychosis, and anxiety. The optimal therapeutic dose of CBD has not yet been determined, and it has been used in a wide dose range from 2.85 to 50 mg/kg/day. The therapeutic effects of CBD appear to emanate from its interaction [...]

Joca, Progress in Neuropsychopharmacology & Biological Psychiatry, 2018 Aug 30; 86: 255-261. Doi: 10.1016/j.pnpbp.2018.06.002 https://www.ncbi.nlm.nih.gov/pubmed/29885468 PMID : 29885468 Abstract Cannabidiol (CBD) is a compound of Cannabis sativa with relevant therapeutic potential in several neuropsychiatric disorders including depression. CBD treatment has shown significant antidepressant-like effects in different rodent preclinical models. However, the mechanisms involved in CBD-induced antidepressant effects are still poorly understood. Therefore, this work aimed at investigating the participation of serotonin (5-HT) and/or noradrenaline (NA) in CBD-induced antidepressant-like effects in [...]
