Newest firstABSTRACTBackground and AimsGiven the rising prevalence of cannabis use as an alternative strategy for managing mental health symptoms, there is a crucial need to understand the determinants of substitution behavior, particularly among midlife women who may experience distinct psychosocial and clinical profiles. This study examined the predictors of cannabis substitution among midlife women by comparing profiles of…
Open article record in new tab ↗Introduction The COVID-19 pandemic was associated with high levels of depression and anxiety among pregnant individuals in the UK, as shown previously in the EPPOCH cohort. However, the relationships between these psychological burdens, pandemic-related stressors, and substance use in the prenatal period have not been systematically investigated. Methods To address this gap, we conducted a cross-sectional analysis…
Prenatal alcohol exposure (PAE) leads to fetal alcohol spectrum disorder (FASD), the most common preventable cause of neurodevelopmental impairment. The classical narrative attributes the clinical picture of FASD exclusively to direct ethanol-induced brain injury. In the present review, we argue that this perspective is incomplete and leads to diagnostic errors, most often to the misdiagnosis of ADHD in children w…
Open article record in new tab ↗Background Entry to higher education coincides with a period of accelerated psychosocial and brain development. Student need for acceptable and accessible well-being and mental health support is straining university resources. Aims To evaluate the acceptability and impact of a digital mental health literacy course tailored for undergraduates and delivered as an accredited interdisciplinary elective. Method Analyse…
Open article record in new tab ↗Depression is a leading cause of disability worldwide, and currently available antidepressants are limited by delayed therapeutic onset, inadequate efficacy in some patients, and adverse effects. G protein-coupled receptors (GPCRs), the largest family of membrane receptors in the central nervous system, regulate neurotransmission, neuroplasticity, neuroinflammation, stress responses, and reward processing, and are…
Rationale Traumatically injured individuals can develop chronic negative psychological sequelae. Improved understanding of contributing, peri-traumatic risk factors is essential to reduce the risk of these consequences. Previous studies have found that peri-traumatic, circulating endocannabinoid concentrations are positively associated with development of post-traumatic stress disorder (PTSD), chronic pain and dep…
Background This SONRIE randomized controlled trial (NCT05849792) examined the effects of a 12-week combined physical exercise and internet-based cognitive-behavioral therapy (iCBT) intervention on endocannabinoid system (ES) biomarkers and physical fitness in adults with mild-to-moderate depression. Methods Eighty adults were randomly assigned 1:1 to an intervention (IG) or control (CG) group. Outcomes included ni…
Background Depression is a leading cause of global disability, affecting approximately 280 million individuals worldwide. Emerging evidence suggests that both physical fitness and endocannabinoids system play significant roles in the pathophysiology and management of depressive disorders. Purpose To examine the associations between physical fitness, in terms of cardiorespiratory fitness (CRF) and muscular fitness…
Purpose of review This scoping review used a five-stage framework to evaluate empirical studies positing anxiety and depression as mechanisms or moderators in associations between cannabis use and sleep. Applicable peer-reviewed studies were identified in Google Scholar and PubMed using relevant search terms (e.g., cannabis, sleep, depression, anxiety). Recent findings Of the 20 articles included, most examined ca…
Open article record in new tab ↗Intolerance of uncertainty is often associated with emerging adult psychopathology, including depression, anxiety, and substance use behaviors. However, positive sibling relationships, which are known to support emerging adult mental health during stressful periods, may mitigate the stress related to uncertainty. Thus, this study investigated the role that sibling relationships may have between uncertainty and psy…
Open article record in new tab ↗BACKGROUND: Major depressive disorder (MDD) is a chronic, recurrent psychiatric illness with challenging management, partly due to the heterogeneity of clinical presentations, unpredictable course and episodes, and variable treatment responses. Cannabis may alleviate depression by promoting glutamate, GABA, and dopamine, but results from previous studies remain controversial or inconsistent. In this study, we aime…
Open article record in new tab ↗BackgroundIndividuals who directly experience major natural disasters are at an increased risk for developing psychological distress and engaging in substance use. Beyond such direct experiences, however, viewing media portrayals of disasters could serve as an indirect means of exposure to a disaster. The objective of this study was to examine the associations between exposure to natural disaster information on so…
Open article record in new tab ↗Background More severe substance use, defined as higher scores on validated measures of problematic use, is increasing within young adult populations. Substance use has been associated with mild traumatic brain injury (mTBI) and elevated symptoms of depression and anxiety. We aimed to understand the relationship between these factors and sex differences in a university sample. Method 894 university students (372 m…
Open article record in new tab ↗Background and hypothesis Evidence suggests a complex interplay among childhood trauma (CT), substance use, and psychopathology in psychosis, yet the precise nature of these relationships remains unclear. Network analysis offers distinct advantages for examining these factors simultaneously, as it can capture multidirectional associations across multiple trauma subtypes, substances, and symptoms that conventional…
ObjectiveAs epidemiological patterns of cannabis use and internalizing problems evolve globally, it is critical to reassess their associations-particularly in the post-legalization and post-pandemic context.MethodsParticipants were assessed in the 2012 Canadian Community Health Survey's Mental Health Component (CCHS-MH; n = 25,113) and 2022 Mental Health and Access to Care Survey (MHACS; n = 9,861), two nationally…
The role of the endocannabinoid system (ECS) in the development of depression and anxiety is being actively studied, with evidence suggesting that elevation of ECS signaling can have anxiolytic and antidepressant properties. The current study explored the therapeutic potential of Oleoyl Serine (OS), an endocannabinoid-like lipid, and HU-910, a synthetic selective Cannabinoid type 2 (CB2) receptors agonist, in depr…
Objective This study examined whether cannabis expectancies mediate the relationship between lifetime cannabis use and symptoms of anxiety or depression among women who screened positive for post-traumatic stress disorder (PTSD). Method A total of 271 women completed an online survey assessing PTSD symptoms, lifetime cannabis use, anxiety and depression symptoms, and cannabis expectancies. Mediation analyses evalu…
Open article record in new tab ↗Background: Suicide prevention strategies in university settings largely rely on detecting explicit suicidal ideation. However, students experiencing severe psychiatric distress may not endorse suicidal thoughts and therefore remain unidentified by ideation-centered screening models. This study aimed to identify and clinically characterize university students with high depressive symptoms, poor sleep quality, and…
Background and aims Epidemiologic research suggests that adolescent cannabis use is associated with psychological distress (i.e. depression and anxiety symptoms); however, most studies have relied on 20th-century data, when cannabis was significantly less potent than today. This study aimed to estimate the association between adolescent cannabis use and psychological distress using contemporary population-based da…
Alzheimer's disease (AD) is primarily recognized for progressive cognitive decline driven by beta-amyloid accumulation and tau pathology. However, many individuals with AD also experience chronic pain and depressive symptoms, which significantly impair daily functioning and quality of life and increase caregiver burden. These non-cognitive features are frequently underrecognized, despite evidence suggesting they s…
