Cannabis and cannabinoid drug development: evaluating botanical versus single molecule approaches Marcel O. Bonn-Miller, Mahmoud A. ElSohly, Mallory J. E. Loflin, Suman Chandra and Ryan Vandrey International Review of Psychiatry, 2018, VOL. 30, NO. 3, 277–284 Doi : 10.1080/09540261.2018.1474730 ABSTRACT Accumulating evidence suggests that the endocannabinoid system is a promising target for the treatment of a variety of health conditions. Two paths of cannabinoid drug development have emerged. One approach is focused on developing medications that are directly derived from the cannabis plant. The other utilizes a single molecule approach whereby individual phytocannabinoids or novel cannabinoids with therapeutic potential are identified and synthesized for pharmaceutical [...]

Choi Cannabis and Cannabinoid Research, 2020,Volume X, Number X, Doi : 10.1089/can.2019.0102 Abstract Introduction: Reports on the neurotoxic and neuroprotective effects of cannabidiol (CBD) have not been in complete accord, showing different and somewhat contradictory results depending upon the brain cell types and experimental conditions employed. This work systematically examines the neuroprotective capability of CBD against oxidative stress (i.e., hydrogen peroxide [H2O2]) as well as its toxicity profile in the in vitro culture platform of primary hippocampal neurons. Materials and Methods: The low cell-density (100 neurons [...]

DOI: 10.1089/can.2019.0098 Abstract Introduction : Cannabidiol (CBD) is known to affect the pharmacokinetics of other drugs through metabolic inhibition of CYP2C19 and CYP3A4. However, there is a lack of in vivo evidence for such drug interactions. Therefore, we investigated the saturability of CBD metabolism and CBD-drug interactions through inhibition of CYP3A in vivo. Materials and Methods : A nanoemulsion formulation of CBD (CBD-NE) was orally administered to [...]

LSD was used in the treatment of anxiety, depression, psychosomatic diseases and addiction. However, most of the studies were not performed under contemporary standards, and it has taken several decades for a resurgence of interest in LSD research and [...]
Lire la suiteAcute and chronic effects of cannabinoids on effort-related decision-making and reward learning: an evaluation of the cannabis ‘amotivational’ hypotheses Will Lawn, Tom P. Freeman, Rebecca A. Pope, Alyssa Joye, Lisa Harvey, Chandni Hindocha, Claire Mokrysz, Abigail Moss, Matthew B. Wall, Michael A.P. Bloomfield, Ravi K. Das, Celia J.A. Morgan, David J. Nutt, H. Valerie Curran Psychopharmacology, 2016, 233, 3537–3552 Doi : 10.1007/s00213-016-4383-x Abstract Rationale : Anecdotally, both acute and chronic cannabis use have been associated with apathy, amotivation, and other reward processing deficits. To date, empirical support for these effects is limited, and no previous studies have assessed both acute effects of Δ-9-tetrahydrocannabinol (THC) and [...]

Doi : 10.3238/arztebl.2017.0627 SUMMARY Background : There are conflicting interpretations of the evidence regarding the efficacy, tolerability, and safety of cannabinoids in pain management and palliative medicine. Methods : We conducted a systematic review (SR) of systematic reviews of randomized controlled trials (RCT) and prospective long-term observational studies of the use of cannabinoids in pain management and palliative medicine. Pertinent publications from January 2009 to January 2017 were retrieved by a selective search in the Cochrane [...]

Doi : 10.1371/journal.pone.0228326 Abstract Background Marijuana is the most popular drug of abuse in the United States. The association between its use and coronary artery disease has not yet been fully elucidated. This study aims to determine the frequency of coronary artery disease among young to middle aged adults presenting with chest pain who currently use marijuana as compared to nonusers. Methods In this retrospective study, 1,420 patients with chest pain or angina equivalent were studied. Only men between 18 [...]

Lire la suiteModern Clinical Research on LSD Matthias E Liechti Neuropsychopharmacology, 2017, 42, 2114–2127. doi : 10.1038/npp.2017.86 All modern clinical studies using the classic hallucinogen lysergic acid diethylamide (LSD) in healthy subjects or patients in the last 25 years are reviewed herein. There were five recent studies in healthy participants and one in patients. In a controlled setting, LSD acutely induced bliss, audiovisual synesthesia, altered meaning of perceptions, derealization, depersonalization, and mystical experiences. These subjective effects of LSD were mediated by the 5-HT2A receptor. LSD increased feelings of closeness to others, openness, trust, and suggestibility. LSD impaired the recognition of sad and fearful faces, reduced left [...]
