McPherson, Debra Srebnik, John M. Roll, Richard K. Ries, and Michael G. McDonell Cannabis and Cannabinoid Research, 2017, 2, 1, 133-138. Doi : 10.1089/can.2017.0006 Abstract Introduction : People with serious mental illness (SMI) use cannabis more than any other illicit drug.

PMID: 31408248 Abstract AIMS : To summarize and evaluate our knowledge of the relationship between heavy cannabis use, Cannabis Use Disorder (CUD), and the brain. METHODS : Narrative review of relevant literature identified through existing systematic reviews, meta-analyses and a PubMed search. Epidemiology, clinical representations, potential causal mechanisms, assessments, treatment and prognosis are discussed. RESULTS : Although causality is unclear, heavy and dependent cannabis use is consistently associated with a high prevalence of comorbid psychiatric disorders and learning and memory impairments that seem [...]

This study investigated the potential of cannabidiol (CBD), a nonintoxicating phytocannabinoid, to reduce cue-induced craving and anxiety, two critical features of addiction that often [...]
Lire la suiteRegular cannabis use is associated with altered activation of central executive and default mode networks even after prolonged abstinence in adolescent users : Results from a complementary meta-analysis Grace Blest-Hopley, Vincent Giampietro and Sagnik Bhattacharyya Neuroscience & Biobehavioral Reviews, 2019, 96, 45–55. doi: 10.1016/j.neubiorev.2018.10.026: 10.1016/j.neubiorev.2018.10.026 PMCID: PMC6331661 PMID: 30395923 Abstract Whether the effects of cannabis use on brain function persist or recover following abstinence remains unclear. Therefore, using meta-analytic techniques, we examined whether functional alterations measured using fMRI persist in cannabis users abstinent for over 25 days (or 600 h) as evidence suggests that the effects on cognitive performance no longer persist beyond this period. Systematic literature search [...]
