Introduction: There has been an increasing amount of research on the consequences of e-cigarette use for respiratory outcomes, which is significant for public health and respiratory medicine. We discuss recent findings and lay out implications for prevention and treatment.

Areas Covered: Based on literature searches using several databases (PubMed, Web of Science, Google Scholar) for keywords, including synonyms, 'e-cigarettes,' with 'pulmonary function,' 'oxidative stress,' and 'inflammation,' we review studies on acute effects of e-cigarette use for measures of pulmonary function and discuss selected laboratory studies on mechanisms of effect, focusing on processes with known relation to respiratory disease; oxidative stress and inflammation.

Introduction: Pictorial health warning labels (HWLs) on waterpipe (WP) tobacco packages represent a better strategy for communicating the health risks associated with WP use and promoting quit intention than text-only. However, the mechanism by which these warnings lead to higher intentions to quit remains unknown.

Aims And Methods: This study explores how pictorial warnings versus text-only induces higher quit intention among a sample of young adult WP smokers in Lebanon.

The experience of perceived ethnic discrimination is prevalent and has harmful effects across various behavioral health processes among Latinx persons. Yet, there is limited work on the association between perceived ethnic discrimination and smoking among this health disparities group. Building from initial work that has demonstrated a relationship between perceived ethnic discrimination and smoking abstinence expectancies, the present study sought to explore mechanisms by which perceived ethnic discrimination may be related to cigarette dependence.

This study compares the impact of pictorial health warning labels (HWLs) and their placements on waterpipe parts (device, tobacco and charcoal packages) on health communication outcomes between waterpipe smokers and nonsmokers in Lebanon. An online randomized crossover experimental study was conducted among young adults (n = 403, August 2021) who observed three conditions of HWLs: pictorial HWLs on the tobacco package, pictorial HWLs on all waterpipe's parts and text-only HWL on the tobacco package in random order. Participants completed post-exposure assessments of health communication outcomes after each image.

Background: Waterpipe (WP) use is rapidly increasing among young people worldwide due to the widespread misperception that it is safer than cigarette smoking. Health warning labels (HWLs) can effectively communicate tobacco-related health risks but have yet to be developed for WP. This study aimed to optimize and adapt a set of 16 pictorial WP-specific HWLs, developed by an international Delphi study, to the Tunisian context.

This study aims to explore the perceived effectiveness of waterpipe (WP) tobacco specific health warning labels (HWLs) among young adult WP smokers and nonsmokers in Lebanon. Before participating in focus group discussions, participants ( = 66; WP smokers = 30; nonsmokers = 36; age 18-33) completed a brief survey to rate the effectiveness of 12 HWLs' and rank them according to four risk themes (WP health effects, WP harm to others, WP-specific harm, and WP harm compared to cigarettes). Differences in HWLs ratings by WP smoking status were examined and the top-ranked HWL in each theme were identified.

Waterpipe tobacco smoking (WTS) has increased substantially in the Eastern Mediterranean Region (EMR), affecting young adults who perceive waterpipe as safer than cigarette smoking. Applying pictorial health warning labels (HWLs) on tobacco products has been effective in communicating health risks associated with tobacco smoking. However, there are few experimental studies that examined pictorial HWLs specific to WTS.
