Cannabis oils are used to treat seizures in drug-resistant epilepsy (DRE). Recent trials provide data on dosing, side effects, and efficacy of CBD, yet there is a paucity of information on THC in epilepsy. Primary [...]

Carney, and Benjamin D. Philpot Journal of Clinical Investigation, 2019 Sep 10, pii: 130419. doi : 10.1172/JCI130419 PMID : 31503547 Abstract Angelman syndrome (AS) is a neurodevelopmental disorder characterized by intellectual disability, lack of speech, ataxia, EEG abnormalities, and epilepsy. Seizures in AS individuals are common, debilitating, and often drug-resistant. Therefore, there is an unmet need for better treatment options. Cannabidiol (CBD), a major phytocannabinoid constituent of cannabis, has antiseizure activity and behavioral benefits in preclinical and [...]

Busch JAMA Published online August 2, 2019 doi:10.1001/jama.2019.10728 Major depressive disorder (MDD) affects approximately 17.3 million adults in the United States,1 with a 12-month and lifetime prevalence of 10.4% and 20.6%, respectively.2 Conducting clinical trials and developing new treatments for depression can be difficult because of spontaneous recovery rates and placebo effects.3 In addition, many patients with chronic and refractory MDD do not experience clinical improvement even after several treatment courses. There is growing interest in the use of exercise and improved nutrition to treat depression,4 [...]

One of the significant barriers to effective treatment is the immunosuppressive pancreatic tumor microenvironment and development of resistance to treatment. New treatment options to increase both the survival and quality of life of patients are urgently needed. This study reports on a new [...]

Elsey Drug Science, Policy and Law, 2017, Vol 3, 1-11 DOI: 10.1177/2050324517723232 Abstract The potential of psychedelic drugs in the treatment of mental health problems is increasingly being recognized. However, relatively little thrust has been given to the suggestion that individuals without any mental health problems may benefit from using psychedelic drugs, and that they may have a right to do so. This review considers contemporary research into the use of psychedelic drugs in healthy individuals, including neurobiological and subjective effects. In line with findings [...]

However, little research has examined enduring changes in traits. This study administered psilocybin to participants who undertook a program of meditation/spiritual practices. Healthy participants were randomized to three groups (25 each): [...]
