Cannabis containing equivalent concentrations of delta‐9‐tetrahydrocannabinol (THC) and cannabidiol (CBD) induces less state anxiety than THC‐dominant cannabis Nadia R. P. W. Hutten, T. R. Arkell, F. Vinckenbosch, J. Schepers, R. C. Kevin, E. L. Theunissen, K. P. C. Kuypers, I. S. McGregor, J. G. Ramaekers Psychopharmacology, 2022, 239, 3731–3741 Doi : 10.1007/s00213-022-06248-9 Abstract Rationale : Delta-9-tetrahydrocannabinol (THC), an active component of cannabis, can cause anxiety in some users during intoxication. Cannabidiol (CBD), another constituent of cannabis, has anxiolytic properties suggesting that cannabis products containing CBD in addition to THC may produce less anxiety than THC-only products. Findings to date around this issue have been inconclusive and [...]
Lire la suiteChemical and Morphological Phenotypes in Breeding of Cannabis sativa L. Gianpaolo Grassi and John M. McPartland in S. Chandra et al. (eds.), Cannabis sativa L. - Botany and Biotechnology, Chapter 6, 2017, 137-160. Doi : 10.1007/978-3-319-54564-6_6 Abstract This chapter has two parts. The first part details five characters that contribute to phenotypic diversity in Cannabis. Cannabinoids can be assayed by quantity (dry weight percentage of cannabinoids in harvested material) or by quality (the THC/CBD ratio, or chemotype). Cannabinoid quality is largely genetic, possibly monogenic. We dissect the monogenic inheritance model (two alleles at a single gene locus). Essential oil is composed of volatile, aromatic terpenoids. [...]

Setting : This study was conducted retrospectively through collecting clinical data from caretakers and clinicians on study outcome variables. Participants were recruited through the MedCann Support and End our Pain charity groups which are patient representative groups that support children [...]
Lire la suiteEpidiolex Plus THC May Lower Seizures in Pediatric Epilepsy Randy Dotinga Medscape.com - Oct 14, 2021. https://www.medscape.com/viewarticle/960842 Children and young adults with epilepsy had fewer seizures after combination treatment with the drug Epidiolex, which contains the cannabidiol (CBD), and various doses of tetrahydrocannabinol (THC), the component of cannabis that makes people high in larger quantities, researchers reported. "THC can contribute to seizure control and mitigation some of the side effects of CBD," said study coauthor and Austin, Tex., child neurologist Karen Keough, MD, in an interview. Keough and colleagues presented their findings at the 50th annual meeting of the Child Neurology Society. In a landmark move, the Food and [...]

Bloomfield British Medical Journal, 2019, 365, l1141 doi : 10.1136/bmj.l1141 What you need to know • Cannabis based products for medicinal use contain cannabinoids derived from the cannabis plant, including Δ9-tetrahydrocannabinol (THC), cannabidiol (CBD), or a combination of THC and CBD. Synthetic cannabinoids for medicinal use typically mimic the effects of specific cannabinoids such as THC • THC is the constituent of cannabis that causes the “high,” whereas CBD is not intoxicating at typical doses. THC and CBD have contrasting mechanisms of action and therapeutic indications; THC [...]

Study protocol for a pilot single-site phase I/II randomised placebo controlled trial Daryl Efron, Kaitlyn Taylor, Jonathan M Payne, Jeremy L Freeman, Noel Cranswick, Melissa Mulraney, Chidambaram Prakash, Katherine J Lee, Katrina Williams BMJ Open, 2020, 10, e034362. doi : 10.1136/bmjopen-2019-034362 Abstract Introduction : Severe behavioural problems (SBPs) are a common contributor to morbidity and reduced quality of life in children with intellectual disability (ID). Current medication treatment for SBP is associated with a high risk of side effects. Innovative and safe interventions are urgently needed. Anecdotal reports and preliminary research suggest that medicinal [...]

Barratt, Tom Decorte, Pekka Hakkarainen, Simon Lenton, Gary Potter, Bernd Werse and Chris Wilkins Drugs and Alcohol Today, 2019, 19, (4), 251-256, Doi : 10.1108/DAT-06-2019-0021 Abstract Purpose – It is conceivable that cannabis cultivators who grow for medical purposes aim to improve the therapeutic index of their cannabis by attempting to produce particular concentrations of CBD and/or THC. The purpose of this paper is to examine whether small-scalemedical cannabis growers differ fromthose growing for recreational reasons in terms of self-assessed concentrations of THC and CBD [...]

No effective medication is currently available for the treatment of the underlying disease and accompanying behavioral symptoms. Cannabinoids might have a beneficial effect, but clinical studies with (low-dose) synthetic THC have not been conclusive. Objective : To test the acceptability, practical aspects, and clinical outcomes of the introduction of a THC/ CBD-based oral medication in severely demented patients in a specialized [...]

Caldera SAGE Open Medical Case Reports, 2020, Volume 8, 1–3 DOI : 10.1177/2050313X20907015 Abstract Opioid medication–related deaths have increased to epidemic proportions in the last decade. This report describes a case of 43-year-old female with a traumatic brain injury who developed chronic pain and opioid dependence. The patient expressed concerns and wanted weaning off opioids. Recent legalization of medical marijuana in Pennsylvania allows us to try it as an alternative to opioids for chronic pain. Medical cannibus has risks associated with administration but is safer than opioids. Our patient [...]
