Newest firstPurpose Nicotine and cannabis are commonly co-used among adolescents and young adults (AYAs). Same session co-use has more negative effects than co-use that does not overlap. Little is known about how or why these products are used within the same session. Enhanced understanding of this behavior pattern can be leveraged to reduce co-use in this population. Methods Connecticut AYAs (15-20 years old) who self-report…
Open article record in new tab ↗Background An estimated 5 to 8 million US children live with a parent who uses cannabis, and most cannabis users report smoking cannabis inside their homes, placing children at risk for cannabis secondhand smoke (cSHS) exposure. Indoor air quality (IAQ) monitoring provides real-time feedback on airborne pollutants and has shown promise in reducing in-home tobacco secondhand smoke exposure, suggesting its potential…
Objective Parents represent a growing yet understudied population of people who use cannabis in the era of legalization. Studies examining how increasing availability of cannabis retail stores affects parental cannabis use, norms, and perceived harm are needed to guide interventions to support families. This longitudinal study examines whether perceived and objectively measured cannabis outlet availability are ass…
Introduction Use of cannabis vaping products has been increasing in Canada. This study examined the prevalence and patterns of use of cannabis vaping products, including higher-risk use, by sex and age. Methods Data were from four cycles of the Canadian Cannabis Survey, an annual web-based survey of people aged ≥ 16 years in Canada. Past 12-month consumers of cannabis for non-medical purposes were analysed (n2020…
Open article record in new tab ↗Background Cannabis has shown mixed results in its association with alcohol urge, which may be explained by individual differences. One such factor, working memory capacity (WMC) is associated with drug-related cue reactivity and implicated in alcohol use and problems. In the current study, we examined whether WMC moderates the acute effect of cannabis on alcohol urge in a randomized placebo-controlled crossover t…
Open article record in new tab ↗Aims To test whether the total consumption model and its extension, the theory of collectivity, apply to adolescent cannabis use. We estimated: (1) whether the distribution of cannabis use frequency was stable over time; (2) whether changes in average cannabis use were mirrored across consumption quantiles; and (3) whether higher average use corresponds with a higher prevalence of high-frequency users. Design Repe…
Open article record in new tab ↗Background Population data on cannabis use-beyond prevalence and frequency of use-in the UK is lacking, yet needed to inform harm reduction messaging about cannabis. This study examined (a) recreational and medical cannabis use; (b) cannabis product use; (c) cannabis risk perceptions via three different routes of administration; (d) how product use and risk perceptions vary by reasons for use and higher risk use.…
Open article record in new tab ↗BACKGROUND: In 2018, the Cannabis Act regulated the production and sale of cannabis for non-medical purposes in Canada. With the aim of continuing to protect the public health and safety of Canadians as the legal cannabis market matures, we conducted a thorough data disaggregation to identify segments of the cannabis consumer base in Canada who are more likely to engage in ‘higher risk’ cannabis use behaviours. Th…
Open article record in new tab ↗Rationale Between periods of use, chronic cannabis consumers may display residual effects on selective cognitive functions, particularly memory and attention. Whether there are comparable deficits in real-world behaviors, such as driving, has not been thoroughly examined. Objectives The current study explored the association between driving simulator performance, cannabis use history, and demographic factors after…
Given the increasing availability of high-potency Δ9-tetrahydrocannabinol (Δ9-THC) products, understanding potency-related effects of Δ9-THC on driving performance is an important public safety issue. This randomized, double-blind, placebo-controlled, within-subjects trial examined the effects of smoked cannabis with varying Δ9-THC concentrations on simulated driving. Adults aged 19–45 who regularly used cannabis…
Background Over the past 2 decades, global rates of cannabis use have risen significantly, especially among young adults. This has corresponded to an increase in cannabis-related problems and hospitalizations. Thus, there has been significant interest in developing new interventions that can help facilitate cannabis cessation and reduce hospitalization rates. Specifically, mobile apps have emerged as scalable and…
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 ↗OBJECTIVE: We aimed to explore how women living in places with legalized recreational cannabis perceive perinatal cannabis use, and how legalization potentially impacts their experiences. METHODS: Between September 2024 and December 2025, we searched databases including PubMed, CINAHL, Scopus, PsycINFO, and Web of Science. All research reports were screened and evaluated based on the inclusion and exclusion criter…
Open article record in new tab ↗Background Cannabis may cause chronic pulmonary disease. Prior studies have been limited by low cannabis exposure, lack of data on tobacco cigarettes, and/or limited numbers of those without tobacco cigarette use. Objective To examine whether inhaled cannabis associated with asthma and chronic obstructive pulmonary disease, independent of tobacco cigarettes. Design Cross-sectional analysis of population-based, nat…
Background and aims The impact of exposure to cannabis dispensaries on young adult cannabis use may depend on how exposures and outcomes are defined. We estimated associations of dispensary exposure with young adult cannabis use across: (a) a government-maintained licensed dispensaries registry versus a web-scraped list of licensed and unlicensed dispensaries; and (b) varying modes of cannabis modes (i.e. smoked,…
Cannabis is commonly smoked and often co-used with tobacco, yet evidence on interventions to reduce smoking harms for people who use cannabis is limited. We systematically reviewed evidence on the efficacy and effectiveness of health education interventions (aiming to increase health literacy, knowledge, or motivation) in reducing cannabis smoking and tobacco smoking among people using cannabis. We searched five d…
Importance Adolescents are exposed to e-cigarette and cannabis content on social media. Understanding associations of these exposures with use and dual use of these products can guide regulations. Objective To assess whether adolescent exposure to e-cigarette and/or cannabis content on social media, including posts by various content creators, is associated with e-cigarette, cannabis, and dual use. Design, setting…
Tobacco and cannabis use are prevalent among adults with HIV and co-use is associated with drug dependence and negative health outcomes such as lung disease. This study examined the co-use of tobacco and cannabis by HIV status overall and by sociodemographics. Data came from the adult sample from the 2021-2023 National Survey on Drug Use and Health. Adjusted multinomial logistic regressions were performed on tobac…
Open article record in new tab ↗Objectives Cannabis legalization has triggered an increase in prenatal cannabis use. Given that tobacco is commonly co-used with cannabis, determining outcomes associated with prenatal cannabis and tobacco co-exposure is crucial. While literature exists regarding the individual effects of prenatal cannabis and tobacco exposure on childhood behaviour, there is a gap regarding their combined use, which may have inte…
Open article record in new tab ↗Background Inhaled combusted cannabis and co-use of combusted cannabis and nicotine electronic cigarettes (ECIGs) are emerging trends among young adults, yet the potential cardiovascular disease risks associated with these substances remain unclear. This study examined whether cannabis use increases cardiovascular disease risk, specifically, arrhythmia risk, as estimated by ventricular repolarization, and whether…
