To use or not to use electronic cigarettes? Reasons for use, stopping use and their behavioural sequelae among Mexicans who smoke.

Introduction: Reasons for using and stopping the use of e-cigarettes and their associations with transitions in nicotine product use are relatively unknown in countries with e-cigarette bans, such as Mexico.

Methods: Data comes from an open cohort of people who smoke in Mexico, surveyed every 4 months from November 2018 to November 2021. Those who smoked and used e-cigarettes at time t (n=904 individuals, 1653 observations) were categorised at 4-month follow-up (t+1): (1) continued 'dual use', (2) exclusive smoking, (3) exclusive use of e-cigarettes or neither product.

Does e-cigarette use predict short-term smoking cessation behaviors among adults who smoke in Mexico? A longitudinal study.

Introduction: This study assessed quit attempts among adults who use cigarettes either exclusively or with e-cigarettes in Mexico, where non-daily smoking predominates.

Methods: An open cohort of Mexican adults who smoke was surveyed every four months from November 2018 to March 2021. Participants followed to the next survey were analyzed (n = 2220 individuals, 4560 observations).

Heated tobacco product use frequency, smoking quit attempts, and smoking reduction among Mexican adult smokers.

Introduction: Heated tobacco products (HTPs) are promoted as less harmful than cigarettes; nonetheless, whether HTPs help smokers quit is uncertain.

Methods: Data from 4067 Mexican adult smokers surveyed longitudinally every four months (November 2019-March 2021) were analyzed. Mixed-effects multinomial models regressed HTP use frequency (no use=reference; monthly; weekly; and daily use) on sociodemographics and tobacco/nicotine-related variables.

Smoking Dependence, Time-Discounting, and Sustained Cessation Behavior: A Longitudinal Study of Predominantly Light Smokers.

Introduction: This study aimed to assess whether two established psychosocial predictors of smoking abstinence, nicotine dependence and time-discounting, also apply to a population of predominantly cigarette light smokers, which is the dominant pattern of smoking in countries like Mexico. Relatively infrequent smoking is increasingly prevalent, yet still harmful, making it important to understand the predictors of cessation in this population.

Aims And Methods: Mexican adult smokers recruited from an online consumer panel were surveyed every 4 months between November 2018 and July 2020.

The validity of self-rated alcohol susceptibility in predicting alcohol use in early adolescents in Latin America.

Background: The measurement of substance use susceptibility was first conceived as part of the preparatory stage that precedes youth smoking initiation and is defined as the lack of a firm commitment not to smoke in the future. Despite being a consistent and validated predictor of smoking initiation, there has been little research on whether susceptibility can predict alcohol use. This study assessed the validity of an adapted alcohol susceptibility measure to predict alcohol consumption among early adolescent students in Argentina and Mexico who had not previously consumed alcohol.

Exposure to e-cigarette advertising and provaping websites, and the social acceptability of their use among nicotine users.

Objectives: To evaluate the prevalence of exposure to Internet communications on and advertising of electronic cigarettes (e-cigarettes) and their association with perceptions of the social acceptability of e-cigarettes in Mexico.

Methods: Data were analyzed from eight surveys (2018-2021) of an online sample of Mexican adult (> 18 years) smokers and dual users (of combustible and electronic cigarettes).

Transitions between tobacco products: Correlates of changes in cigarette smoking and e-cigarette use among exclusive adult smokers and dual users in Mexico.

This study examined transitions in tobacco products use among Mexican smokers and dual users. Data were analyzed from exclusive smokers (n = 2,946) and dual users (n = 1,643) recruited from an online consumer research panel and surveyed every-four months from November 2018 to April 2021. For exclusive smokers, estimated transitions were (time "t + 1" four months after prior survey): a) remain as exclusive smokers; b) dual use; c) exclusive e-cigarette use or quit both products.

The fallacy of science is science: the impact of conflict of interest in vaping articles.

Objective: To explore the association between reporting conflict of interest (COI) and having a positive outcome toward vaping in scientific articles.

Methods: A cross-sectional study that analyzed a sample of 697 articles published between 2017 and 2020 regarding vaping. Information on the reporting of COI, type of COI (no conflict, conflict with the tobacco industry, pharmaceutical industry, or other), and country of publication were collected.

Strategies to enhance the effects of pictorial warnings for cigarettes: results from a discrete choice experiment.

Aims: To measure the effects of changing attributes of pictorial health warning labels (HWLs) on cigarette packs in a country that has already implemented pictorial HWLs.

Measures: For each choice set, participants were presented with two cigarette packs and asked the following three questions: (1) 'If only these two cigarette packs were available, which would you buy?'; (2) 'Each of these two packs has warnings on the front and back about the health effects of smoking. Which of these warnings best informs you about the dangers from smoking?'; and (3) 'Which warning most makes you think about quitting smoking?'.

Smoking Behaviors, Mental Health, and Risk Perceptions during the Beginning of the COVID-19 Pandemic among Mexican Adult Smokers.

Mexico is one of the countries most affected by COVID-19.

Assessing cigarette packaging and labelling policy effects on early adolescents: results from a discrete choice experiment.

Introduction: Cigarette packaging is a primary channel for tobacco advertising, particularly in countries where traditional channels are restricted. The current study evaluated the independent and interactive effects of cigarette packaging and health warning label (HWL) characteristics on perceived appeal of cigarette brands for early adolescents in Mexico.

Methods: A discrete choice experiment (DCE) was conducted with early adolescents, aged 12-14 years (n=4251).

Adult Smokers' Awareness and Interest in Trying Heated Tobacco Products: Perspectives from Mexico, where HTPs and E-Cigarettes Are Banned.

Background: We evaluated smokers' perceptions of heated tobacco products (HTPs) in Mexico, where industry publically lobbied to introduce HTPs into this country that banned both HTPs and e-cigarettes.

Methods: Online surveys (November 2018 to July 2019) were analyzed from adults who only smoked cigarettes ( = 2091) or who smoked and used e-cigarettes ("dual users" = 1128). Logistic models regressed HTP awareness, interest to trying HTPs, and having seen HTPs for sale (only among aware participants) on sociodemographics and tobacco-related variables.

Unlabelled: This study describes the prevalence and correlates of adult smokers' discussions about electronic cigarettes (e-cigarettes) with health professionals (HPs), including whether these discussions may lead smokers and vapers to use e-cigarettes for smoking cessation.

Methods: We analyzed data from an online survey of Mexican smokers recruited from a consumer panel for marketing research. Participants who had visited an HP in the prior four months ( = 1073) were asked about discussions of e-cigarettes during that visit and whether this led them to try to quit.
