Background and Aims
People with mental ill health are more likely to smoke and experience smoking‐related harm than those without. Switching from combustible tobacco to lower‐risk nicotine‐containing products may be of benefit; however, misperceptions of harm may prevent their use. We aimed to assess, among adults with and without mental ill health, (1) perceptions of harm from nicotine and relative...
Aims
To understand dual users’ cigarette and e‐cigarette use patterns, including the contexts in which they vape versus smoke and to understand how environmental and internal contexts and smoking patterns differ between dual users and exclusive smokers.
Design
Longitudinal observational trial.
Setting
Research center in Wisconsin, USA.
Participants
Adult dual users (n = 162) and adults who...
Background and aims
Smoking is extremely common among adults experiencing homelessness, but there is lack of evidence for treatment efficacy. E‐cigarettes are an effective quitting aid, but they have not been widely tested in smokers with complex health and social needs. Here we build upon our cluster feasibility trial and evaluate the offer of an e‐cigarette or usual care to smokers accessing a...
Aim
To quantify the trends in frequent and occasional cannabis vaping, demographic differences and concurrent nicotine and alcohol use.
Design
Observational study. Survey‐weighted multinomial logistic regression models assessed trends and disparities in past 30‐day cannabis use. Trends were assessed overall and by sex, race/ethnicity, parental education and urbanicity. Multinomial logistic regression...
Aim
To (i) estimate the prevalence of adolescent vaping in 47 lower‐middle, upper‐middle and high‐income countries, and (ii) test the association between implementation of World Health Organisation (WHO) tobacco control policies and adolescent e‐cigarette use (also known as vaping) in 44 countries where implementation data were available.
Design
Cross‐sectional surveys.
Settings
A total of 47...
Aims
To identify subpopulations of dual users of combustible and electronic cigarettes using current smoking and vaping behaviors.
Design
Secondary analysis of baseline data from a randomized controlled trial testing a smoking cessation intervention for dual users. Finite mixture modeling of frequency, quantity, and dependence on combustible and electronic cigarettes was used to identify classes...
Aims
To measure the prevalence and changes in smokers’ discussions with health professionals (HPs) about nicotine vaping products (NVPs) and HPs’ recommendations about NVPs between 2016 and 2020, and their associations with tobacco product use transitions.
Design
Cohort study using multinomial logistic regression analyses on data from waves 1 (2016), 2 (2018) and 3 (2020) from the International...
Background and Aims
Although over half of United States states have passed taxes on electronic nicotine delivery systems (ENDS), recent evidence links ENDS tax rates to increases in smoking, suggesting potentially substantive health costs. Overall health implications will depend on how these taxes affect transitions from experimentation to regular smoking and vaping. Current analyses have not assessed...
Aims
To estimate the association of longitudinal patterns of e‐cigarette use with cigarette smoking abstinence, after accounting for time‐dependent confounding and selection bias.
Design
Secondary analysis of longitudinal national cohort data. Using marginal structural models and four waves of the population assessment of tobacco and health (wave 1, 2013–14; wave 2, 2014–15; wave 3, 2015–16; wave...
