BACKGROUND Cannabis-induced psychosis presents complex sex-based disparities that challenge traditional epidemiological patterns. While males demonstrate higher cannabis use rates, emerging evidence reveals paradoxical vulnerability patterns where females may show heightened susceptibility to cannabis-related psychotic outcomes despite lower consumption rates. OBJECTIVE To map evidence for...

BACKGROUND AND AIMS Although many people who use cannabis report mood-enhancing effects, affective responses are thought to vary within and between individuals. This study examined the bidirectional associations between momentary affect and cannabis use and the potential moderating role of emotion regulation in this. DESIGN Intensive longitudinal observational study using experience sampling...

Background Prenatal cannabidiol (CBD) consumption is increasing, driven by a perception of safety relative to Δ9-tetrahydrocannabinol (THC). However, the neurodevelopmental risks of gestational CBD remain largely uncharacterized. Methods Using a sex-disaggregated framework, we investigated adult (P100–140) mouse offspring following in utero exposure (GD5-18; 3 mg/kg) to THC or CBD. Behavioral...

Background: Individuals with attention-deficit hyperactivity disorder (ADHD) are at increased risk for cannabis misuse, with increasing prevalence among young adults. Existing evidence suggests that cannabis can have therapeutic effects on ADHD symptoms, and continued use may be partly driven by perceived improvements in symptom-related deficits. To investigate the neural evidence for these...

Cannabis use is frequently detected in motor vehicle crashes. While research has found an increased crash risk of driving under the influence of cannabis, research on the effects of cannabis, or THC, on driving behaviour seems to be somewhat limited to vehicle control. Our objectives were to map available research into the effects of THC on higher-order driving skills during actual driving. A...

Background Recently, there has been a significant rise in potency (% tetrahydrocannabinol (THC)) of cannabis products globally. As such, there is a need for a better understanding of the relationship between cannabis potency and mental health outcomes, especially in a developmentally vulnerable population such as adolescents and young adults. Aims The objective of this scoping review was to...

Background: Cannabis remains the most widely used illicit psychoactive substance in Europe, and Germany's landmark 2024 partial legalisation of recreational cannabis has made the clinical evidence base for cannabis-psychosis associations particularly relevant for German public health and forensic psychiatry policy. A growing body of evidence suggests that heavy cannabis use is associated with...

Cannabis use often begins in adolescence and young adulthood, when anxiety, depression, psychosis, and bipolar disorder typically first develop. Young people aged in their mid-teens to mid-twenties who engage in daily cannabis use and develop a cannabis use disorder have a higher prevalence of these mental disorders. We assessed the coherence of evidence from epidemiological, genetic,...

The presence of cannabidiol (CBD) in cannabis may alter cannabinoid pharmacokinetics, however previous research has produced mixed results. Furthermore, no prior research has explored how cannabinoid pharmacokinetics are moderated by age. Using vaporised and inhaled cannabis, we aimed to (1) examine the effect of CBD on the plasma concentration of delta-9-tetrahydrocannabinol (THC) and its...

Cannabis use is a recognised risk factor for psychotic disorders, particularly among young adults. We report a case of cannabisassociated psychosis in a 24-year-old man presenting with persistent somatic delusions and Koro-like symptoms. Despite normal neurological, ophthalmological, and urological evaluations, the patient developed a fixed belief of bodily “power” shifting sides, resulting in...
