Future Directions for Clinical Psychedelic Research : The Relaxed Symptom Network Evan Lewis-Healey, Ruben Laukkonen , Michiel van Elk Pre-Print, May 2021 Doi : 10.31234/osf.io/q3ymd Abstract Recent clinical trials have demonstrated that psilocybin may have strong antidepressant effects, and may be effective in the treatment of depressive disorders when embedded in a psychotherapeutic protocol (psychedelic-assisted psychotherapy; PAP). There are now dozens of registered and ongoing clinical trials that intend to test for the efficacy of psilocybin within a psychotherapeutic protocol. Despite promising results, the mechanism(s) that may be responsible for the antidepressant effects of PAP are still hotly contested. In this paper, we provide a [...]

Several state-of-the-art studies have provided new insight into the mechanisms of action of psilocybin and its therapeutic potential. Nevertheless, many questions remain unanswered. With this review, we provide an overview of the current state of research on the potential mechanisms of psilocybin, its antidepressant potential, and the associated risks [...]

Frank, Tallan Black, Pramodkumar D. Jadhav, Larry A. Holbrook & Robert B. Laprairie Scientific Reports, www.nature.com, 2020, 10, 20405, 1-13. Doi : 10.1038/s41598-020-77175-y The Cannabis sativa plant contains more than 120 cannabinoids. With the exceptions of Δ9-tetrahydro-cannabinol (Δ9-THC) and cannabidiol (CBD), comparatively little is known about the pharmacology of the less-abundant plant-derived (phyto) cannabinoids. The best-studied transducers of cannabinoid-dependent effects are type 1 and type 2 cannabinoid receptors (CB1R, CB2R). Partial agonism of CB1R by Δ9-THC is [...]

Several studies are being conducted worldwide on cannabidiol use in ASD; however, these studies are still ongoing, and data on the effects of its use is very limited. In this study we aimed to report the experience of parents who administer, [...]

There has been growing attention in recent years on its potential therapeutic efficacy as municipalities and legislative bodies in the United States, Canada, and other countries grapple with enacting policy to facilitate the use of cannabis or its constituents for medical purposes. There are 4550 chemical compounds and 4100 phytocannabinoids [...]

Canada (since 2001) and the Netherlands (since 2003) have government-run programs, in which quality-controlled herbal cannabis is supplied by specialized and licensed companies. Several other countries are now setting up their own programs (Israel, Czech Republic, Switzerland) or import products from the Dutch program (Italy, Finland, Germany, Switzerland). In the US, despite strong opposition by the federal government, so far 18 states including the District of Columbia have introduced laws to permit “medical marijuana use” [...]
