“Literature on the association between cannabis use and body mass index (BMI) among adults suggests that greater cannabis use is associated with a lower BMI. However, results are mixed among adolescents, with both cross-sectional and longitudinal studies finding positive, negative, and nonsignificant associations between cannabis use and BMI.
This longitudinal study aims to shed light on these associations by prospectively examining the associations between cannabis use and BMI across a 2-year window in a large sample of adolescent cannabis users.
Results: Results showed that baseline BMI predicted a positive and significant association with cannabis use slope. In addition, there was a significant and negative correlation between the cannabis use slope and the BMI slope. These significant associations remained after controlling for relevant covariates.
Conclusions: Results are consistent with the adult literature that reports a negative association between cannabis use and BMI. Future research should focus on uncovering the mechanisms that may drive the association between cannabis use and BMI.”
“Recent studies have suggested that cannabidiol (CBD) could interconvert into Delta-8- and Delta-9- tetrahydrocannabinol. Thus, we tested the plasma samples of 120 healthy human subjects (60 male and 60 female), 60 in fasting and the other 60 under normal feeding conditions after acute administration of an oral solution containing CBD 300 mg.
The results showed that THC was not detected in plasma after the administration of CBD, and those study participants did not present psychotomimetic effects.
The findings presented here are consistent with previous evidence suggesting that the oral administration of CBD in a corn oil formulation is a safe route for the administration of the active substance without bioconversion to THC in humans.”
“Dravet syndrome is a severe, genetic form of paediatric epilepsy associated with premature mortality and co-morbidities such as anxiety, depression, autism, motor dysfunction and memory deficits. Cannabidiol is an approved anticonvulsive drug in the United States and Europe for seizures associated with Dravet syndrome in patients 2 years of age and older. We investigated its potential to prevent premature mortality and improve associated co-morbidities.
The efficacy of sub-chronic cannabidiol administration in two mouse models of Dravet syndrome was investigated. The effect of cannabidiol on neonatal welfare and survival was studied using Scn1a-/- mice. We then used a hybrid, heterozygote Scn1a+/- mouse model to study the effect of cannabidiol on survival and behavioural co-morbidities: motor deficits (rotarod and static-beam test), gait abnormality (gait test), social anxiety (social interaction test), anxiety-like (elevated plus maze) and depressive-like behaviours (sucrose preference test) and cognitive impairment (radial arm maze test).
In Scn1a-/- mice, cannabidiol increased survival and delayed worsening of neonatal welfare. In Scn1a+/- mice, chronic cannabidiol administration did not show any adverse effect on motor function and gait, reduced premature mortality, improved social behaviour and memory function, and reduced anxiety-like and depressive-like behaviours.
We are the first to demonstrate a potential disease-modifying effect of cannabidiol in animal models of Dravet syndrome. Cannabidiol treatment reduced premature mortality and improved several behavioural co-morbidities in Dravet syndrome mice. These crucial findings may be translated into human therapy to address behavioural co-morbidities associated with Dravet syndrome.”

“Advances in the development of drugs with novel mechanisms of action have not been sufficient to significantly reduce the percentage of patients presenting drug-resistant epilepsy. This lack of satisfactory clinical results has led to the search for more effective treatment alternatives with new mechanisms of action.
The aim of this study is to examine epidemiological aspects of the use of cannabis-based products for the treatment of epilepsy, with particular emphasis on the main mechanisms of action, indications for use, clinical efficacy, and safety.
In recent years there has been growing interest in the use of cannabis-based products for the treatment of a wide range of diseases, including epilepsy. The cannabis plant is currently known to contain more than 100 terpenophenolic compounds, known as cannabinoids. The 2 most abundant are delta-9-tetrahydrocannabinol and cannabidiol.
Studies of preclinical models of epilepsy have shown that these cannabinoids have anticonvulsant properties, and 100% purified cannabidiol and cannabidiol-enriched cannabis extracts are now being used to treat epilepsy in humans. Several open-label studies and randomised controlled clinical trials have demonstrated the efficacy and safety of these products.”

“Cannabinoids, broadly speaking, are a class of biological compounds that bind to cannabinoid receptors. They are most frequently sourced from and associated with the plants of the Cannabis genus, including Cannabis sativa, Cannabis indica, and Cannabis ruderalis.
The earliest known use of cannabinoids dates back 5,000 years ago in modern Romania, while the documentation of the earliest medical dates back to around 400 AD. However, formal extraction, isolation, and structural elucidation of cannabinoids have taken place rather recently in the late 19th and early 20th centuries. Since then, numerous advancements have been made in further isolating naturally occurring cannabinoids, synthesizing artificial equivalents, and discovering the endogenous the endocannabinoid system in mammals, reptiles, fish, and birds.”
“The aim of this study was to compare the micro-morphological features of two different non-drug Cannabis sativa L. biotypes (Chinese accession G-309 and one fibrante variety) and to evaluate the phytochemical profile as well as some biological properties of the essential oils (EOs) obtained by hydrodistillation of dried flowering tops. After a micro-morphological evaluation by scanning electron microscopy, the phytochemical composition was analysed by GC-FID and GC-MS analyses.
Antioxidant and anti-acetylcholinesterase properties were investigated by several in vitro cell-free assays, while neuroactive effects were evaluated on mouse cortical neuronal as well as human iPS cell-derived central nervous system cells grown on MEA chips. Both EOs showed strong antioxidant properties mainly attributable to the high content of hydroxylated compounds as well as significant anti-acetylcholinesterase activities (IC50 74.64 and 57.31 μg/ml for Chinese accession and fibrante variety, respectively).
Furthermore, they showed a concentration-dependent inhibition of spontaneous electrical activity of human and mouse neuronal networks, with the fibrante variety, which showed the best activity (MFR, IC50 0.71 and 10.60 μg/ml, respectively). The observed biological activities could be due to a synergic effect between terpenes and phytocannabinoids, although in vivo studies, which clarify the molecular mechanism, are still lacking.”
“Despite the increasing prevalence and acceptance of the medical cannabis use among the general public, the evidence required by physicians to use cannabis as a treatment is generally lacking. Research on the health effects of cannabis and cannabinoids has been limited worldwide, leaving patients, health care professionals, and policymakers without the evidence they need to make sound decisions regarding the use of cannabis and cannabinoids.
This case study outlines an intervention that involved a patient integrating medical cannabis into her treatment to better manage a generalized anxiety disorder and the debilitating symptoms of vertigo. This case demonstrates how the patient drastically improved her quality of life and reinforces the need for more rigorous testing on the use of medical cannabis to support patients and better manage the symptoms associated with their medical conditions.”

“Cannabis sativa or Indian hemp (subfamily Cannaboideae of family Moraceae) is an annual herbaceous plant, native to central and western Asia, cultivated for medicinal properties and for hemp, which is a natural textile fiber. The plant contains over 400 chemical compounds, of which approximately 80 biologically active chemical molecules. The most important cannabis compounds are cannabinoids formed by a terpene combined with resorcinol, or, according to a different nomenclature, by a benzopyranic ring system. There are about sixty cannabinoids, of which the most important psychoactive compound is tetrahydrocannabinol (TCH), in particular the isomer delta (Δ9-THC). Other identified compounds are cannabidiol (CBD), cannabigerol (CBG), cannabinol (CBN), cannabichromene (CBC), and olivetol. In addition to cannabinoids, the plant contains terpenoids such as beta-myrcene, beta-caryophyllene, d-limonene, linalool, piperidine, and p-cymene, as well as flavonoids such as quercetin.”
