Support for banning sale of smoked tobacco products among adults who smoke: findings from the International Tobacco Control Four Country Smoking and Vaping Surveys (2018-2022).

Background: Many people continue to smoke despite strong policies to deter use, thus stronger regulatory measures may be required. In four high-income countries, we examined whether people who smoke would support a total ban on smoked tobacco products under two differing policy scenarios.

Methods: Data were from 14 363 adults (≥18) who smoked cigarettes (≥monthly) and participated in at least one of the 2018, 2020 or 2022 International Tobacco Control Four Country Smoking and Vaping Surveys in Australia, Canada, England and the USA.

Awareness, trial and use of heated tobacco products among adult cigarette smokers and e-cigarette users: findings from the 2018 ITC Four Country Smoking and Vaping Survey.

Objective: To evaluate heated tobacco product (HTP) awareness, trial and current use among adult cigarette smokers and vaping product users in four countries with varying regulations governing HTP sales.

Design: Data came from Wave 2 of the ITC Four Country Smoking and Vaping Survey, collected from February to July 2018. Respondents were current and former smokers and/or users of vaping products (18 years or older) from Canada (CA; n=3778), England (EN; n=4848), the USA (US; n=2846) and Australia (AU; n=1515).

Cross-country comparison of cigarette and vaping product marketing exposure and use: findings from 2016 ITC Four Country Smoking and Vaping Survey.

Objective: To compare exposure to and use of certain cigarette and vaping product marketing among adult smokers and vapers in four countries with contrasting regulations-Australia (AU), Canada, England and the USA.

Data Sources: Adult smokers and vapers (n=12 294) from the 2016 International Tobacco Control (ITC) Four Country Smoking and Vaping Survey (4CV1).

Analysis: Self-reported exposure to cigarette and vaping product advertising through point-of-sale, websites/social media, emails/texts, as well as exposure to and use of price offers were assessed for country differences using logistic regression models adjusted for multiple covariates.

Tobacco smoke exposure in public places and workplaces after smoke-free policy implementation: a longitudinal analysis of smoker cohorts in Mexico and Uruguay.

Objective: To determine the prevalence, correlates and changes in secondhand smoke (SHS) exposure over the period after comprehensive smoke-free policy implementation in two Latin American countries.

Methods: Data were analysed from population-based representative samples of adult smokers and recent quitters from the 2008 and 2010 waves of the International Tobacco Control Policy Evaluation Survey in Mexico (n = 1766 and 1840, respectively) and Uruguay (n = 1379 and 1411, respectively). Prevalence of SHS exposure was estimated for regulated venues, and generalized estimating equations were used to determine correlates of SHS exposure.

Cigarette prices, cigarette expenditure and smoking-induced deprivation: findings from the International Tobacco Control Mexico survey.

Aim: Mexico implemented annual tax increases between 2009 and 2011. We examined among current smokers the association of price paid per cigarette and daily cigarette expenditure with smoking-induced deprivation (SID) and whether the association of price or expenditure with SID varies by income.

Methods: We used data (n=2410) from three waves of the International Tobacco Control Mexico survey (ie, 2008, 2010, 2011) and employed logistic regression to estimate the association of price paid per cigarette and daily cigarette expenditure with the probability of SID ('In the last 6 months, have you spent money on cigarettes that you knew would be better spent on household essentials like food?').

Cigarette packet warning labels can prevent relapse: findings from the International Tobacco Control 4-Country policy evaluation cohort study.

Objectives: To investigate the links between health warning labels (WLs) on cigarette packets and relapse among recently quit smokers.

Design: Prospective longitudinal cohort survey.

Setting: Australia, Canada, the UK and the USA.
