Cannabis use can cause a subjective experience of temporal perception alteration and increases the risk of emergence of mental illnesses such as psychotic and mood disorders. In this framework, we systematically reviewed the findings regarding the clinical, cognitive, and neurobiological correlates of time alterations due to cannabis consumption. According to preclinical results, cannabis exerts a dose-dependent time overestimation, associated with motor inhibition and circadian alterations. Clinical results reported that cannabis impair time estimation and time reproduction abilities, causing subjective temporal fragmentation and depersonalization symptoms. The alteration of timing mediated by cannabis use might depend on a dopaminergic indirect action and on structural, functional, and metabolic alterations of the cerebello-thalamo-cortical circuit. Despite the potential interest, however, only few studies explored the link between cannabis-induced alterations of time processing and psychiatric symptoms.

Drug resistance is seen early in many patients, and the management of TSC associated epilepsy remain a major challenge for clinicians. In 2018 clinical recommendations for the management of TSC associated epilepsy were published by a panel of European experts. In the last five years considerable progress has been made in understanding the neurobiology of epileptogenesis and three interventional randomized controlled trials have changed the therapeutic approach for the management of TSC associated epilepsy. Pre-symptomatic treatment with vigabatrin may delay seizure onset, may reduce seizure severity and reduce the risk of epileptic encephalopathy.

Zika virus (ZIKV) is a virus transmitted mainly by the Aedes aegypti mosquitoes, which causes neurological diseases, such as microcephaly and Guillain-Barre syndrome. Although the frequency of viral outbreaks has increased recently, no vaccinations or particular chemotherapeutic treatments are available for ZIKV infection. The major aim of this study was to explore the in vitro antiviral activity of CBD against ZIKV, expanding also to other dissimilar viruses.

Cannabidiol (CBD), an extract of hemp species, has recently attracted increased attention as a cancer treatment, but Δ9-THC is also requiring explored pharmacological application. This study evaluated the pharmacological effects of Δ9-THC in two human colorectal cancer cell lines. We inves-tigated whether Δ9-THC treatment induces cell death in human colorectal cancer cells.

This was a double-blind, randomized, placebo-controlled study conducted between May and November 2022. Participants were randomized to receive either (a) placebo, (b) 20 mg CBN, (c) 20 mg CBN + 10 mg CBD, (d) 20 mg CBN + 20 mg CBD, or (e) 20 mg CBN + 100 mg CBD for seven consecutive nights. Participants were 18–55 years of age who self-rated sleep quality as “very poor” or “poor.” The primary endpoint was sleep quality, while secondary endpoints included sleep onset latency, number of awakenings, wake after sleep onset (WASO), overall sleep disturbance, and daytime fatigue

Yet >50% of pregnancies in women with epilepsy are unintended, making fetal exposure to CBD possible. As a small-molecule, highly lipid-soluble drug, CBD is likely to distribute into the placenta and cross it. To estimate the placental distribution profile of CBD and its potential short-term placental effects, we conducted an ex vivo perfusion study in human placentas.

This study examined baseline prevalence and changes in prescription anxiety medication use three months following MM treatment initiation among individuals with these qualifying conditions. The study sample was comprised of 108 adults with anxiety or PTSD as a referring condition; they were enrolled in a longitudinal study evaluating biopsychosocial outcomes in new MM patients. Consenting participants completed an assessment battery at baseline and Month 3 (n = 94, 87 % follow-up rate) that included a measure of anxiety severity and questions about current anxiety medication prescription and desired (baseline) and actual (Month 3) reductions in medication use.

The major volatile constituents include monoterpenes, sesquiterpenes, and their oxygenated derivates. In particular, the compounds ß-myrcene, D-(+)-limonene, ß-caryophyllene, and terpinolene are often found in greatest amounts, which has led to their use in chemotaxonomic classification schemes and legal Cannabis sativa L. product labeling. While these compounds contribute to the characteristic aroma of Cannabis sativa L. and may help differentiate varieties on a broad level, their importance in producing specific aromas is not well understood. Here, we show that across Cannabis sativa L. varieties with divergent aromas, terpene expression remains remarkably similar, indicating their benign contribution to these unique, specific scents.
