Newest firstBackground Cannabis use is increasingly common among collegiate athletes. While acute tetrahydrocannabinol (THC) effects are well documented, the chronic impact on game-speed cognition, defined as the ability to perceive, decide, and act within sub-second windows, remains poorly quantified. The current study examined whether chronic THC use degrades football specific game-speed cognition and reaction times. Method…
Open article record in new tab ↗Background/objectives Cannabis use has a particularly high prevalence in individuals with psychotic disorders. Although cannabis use is generally associated with cognitive impairments in the general population, its impact on cognition in psychosis remains controversial. This study aimed to investigate the association between cannabis use and cognitive performance in a cohort of individuals affected by psychotic di…
Open article record in new tab ↗Introduction Cannabis use during adolescence and young adulthood has been associated with neurocognitive alterations. However, limited attention has been paid to whether these findings vary according to developmental stage and regional context. This systematic review examined the neurocognitive effects of cannabis use in adolescents and young adults, with particular attention to age-related patterns and geographic…
Open article record in new tab ↗Oral cannabidiol (CBD) treatment has been suggested to alleviate severe symptoms of autism spectrum disorder (ASD). While many CBD preparations have been studied in clinical trials involving ASD, none has used purified CBD preparations or preparations approved by the U.S. Food and Drug Administration, nor have they focused on children with ASD with higher support needs. Previous studies have identified several can…
Background Medical cannabis is now commonly prescribed for a range of chronic health conditions. Many medical cannabis products contain delta-9-tetrahydrocannabinol (THC), the intoxicating component in cannabis, though it is unclear whether these products produce impairment when used as prescribed and at therapeutic doses. With current Australian laws prohibiting driving with any amount of THC in one's system, thi…
Open article record in new tab ↗Adolescents experience extensive neurocognitive development, with cannabis use potentially impacting developmental trajectories. Here, we comprehensively assess the influence of adolescent cannabis use onset on neurocognitive trajectories and consider how recent delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) may influence neurocognition. We use the large, diverse longitudinal Adolescent Brain Cognitive D…
People with HIV (PWH) exhibit persistent immune activation despite suppressive antiretroviral therapy, contributing to neurocognitive vulnerability. Marijuana use is common among PWH and may influence inflammatory pathways, but its in vivo immunologic effects in treated HIV remain unclear. In this cross-sectional study (Durham, NC; 2021-2023), 238 adults with and without HIV were grouped by chronic marijuana use.…
Background/Objectives: Alzheimer's disease (AD) is a neurodegenerative disease for which there are no highly effective treatments, which highlights the need for novel therapeutics. Cannabidiol (CBD) has demonstrated antioxidant, anti-inflammatory and neuroprotective properties. Chronic CBD treatment (20 mg/kg and 50 mg/kg) reverses social recognition memory deficits of APPSwe/PS1∆E9 (APP/PS1) transgenic mice; howe…
Open article record in new tab ↗Prospective memory (PM) deficits are common among people with HIV (PWH) and are linked to poor clinical outcomes. Risk factors for PM deficits in PWH are poorly understood. While cannabis use is associated with worse PM in people without HIV, it is unclear whether this association generalizes to PWH. Three hundred and seven PWH (79% with regular cannabis use) completed the Memory for Intentions Test (MIST). Associ…
Open article record in new tab ↗Cury et al. present the first randomized placebo-controlled trial of a low-dose balanced tetrahydrocannabinol–cannabidiol extract targeting cognition in Alzheimer’s disease (AD). The study marks a milestone in a field long dominated by anecdotes and low-certainty evidence. While it demonstrated modest cognitive improvement on the Mini-Mental State Examination, the lack of functional and behavioral outcomes raises…
Open article record in new tab ↗Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, memory impairment, and behavioral disturbances. While its pathogenesis is complex, increasing evidence supports the role of an imbalance between excitatory and inhibitory (E/I) neuronal activity in disease progression. E/I imbalance contributes to synaptic impairment, network hypersynchrony, and ultimately cogn…
Cocaine use disorder (CUD) remains a major public health challenge with limited effective therapeutic options. Cannabidiol (CBD) has been proposed as a potential treatment due to its neuroprotective and anti-craving properties. This scoping review aims to synthesize and map the existing evidence from clinical trials evaluating CBD's effects on craving reduction, relapse prevention, cognitive function, and emotiona…
Objectives To examine next-day cognitive performance and subjective drug effects after smoking cannabis and to assess associations between performance and cannabinoid concentrations in blood and oral fluid. Methods In this observational study, healthy adults who regularly used cannabis (mean age 30 years; n = 65) smoked a legally purchased pre-rolled "joint" at night and were tested the next day, 12-15 h later. He…
Background Substance use has consistently been linked with cognitive impairments. However, most previous studies have focused on highly selective samples of individuals with chronic substance use disorders and have typically relied solely on self-reports. The associations between recreational use patterns of single or multiple substances and cognitive functioning in representative samples remain unclear. Methods W…
Maternal cannabis use in pregnancy is reported to be associated with perinatal and neurodevelopmental outcomes in offspring. Such associations, however, may be biased by residual confounding by socioeconomic position (SEP). To assess confounding, we use paternal cannabis use in pregnancy as a negative control exposure. We use data from 15,013 mother-father-child trios from the ALSPAC birth cohort, with participant…
Open article record in new tab ↗Background Adolescence is a key developmental period associated with an increased risk of experiencing cannabis-related problems. Identifying modifiable risk factors prior to the onset of cannabis use could help inform preventative interventions. Method Analysis nested within a UK prospective birth cohort study, the Avon Longitudinal Study of Parents and Children. Participants (n = 6,049) provided data on cannabis…
Open article record in new tab ↗Objective We evaluated performance-based differences in neuropsychological functioning in older adults (age 65+) across the dementia continuum (cognitively intact, mild cognitive impairment, and dementia) according to recent cannabis use (past six months). Method A sample of 540 older adults from a well-characterized observational cohort was included for analysis. Participants completed a standardized questionnair…
Background Schizophrenia is a serious psychiatric disorder that affects over 24 million people worldwide. Current therapies treat positive symptoms but show little efficacy for negative and cognitive symptoms, which can impact quality of life. Development of effective medication for this unmet medical need is imperative. Phytocannabinoids, such as cannabidivarin (CBDV), show promising results for the treatment of…
Background and hypothesis Cognitive impairments are particularly disabling for patients with a psychotic disorder and often persist despite optimization of antipsychotic treatment. Thus, motivating an extension of the research focus on the endocannabinoid system. The aim of this study was to evaluate group differences in brain fatty acid amid hydrolase (FAAH), an endocannabinoid enzyme between first-episode psycho…
Background Recent preclinical studies have shown sex-dependent antidepressant-like responses of cannabidiol in adolescence, which were dependent on biological sex, early-life stress, and dose. In particular, cannabidiol (10 mg/kg) induced acute and sustained antidepressant-like responses in adolescent male rats, while it lacked efficacy in females. This follow-up study aimed at further characterizing cannabidiol's…
