The objectives of this study were to systematically review: 1. Whether tobacco control MMCs affect smoking-related outcomes among people with mental illness. 2. Cost-effectiveness. Methods D...
Article
Introduction: This study aimed to estimate prevalence rates of mental health symptoms (anxiety, depression, and overall psychological distress) by tobacco smoking status, and associations between such symptoms and the level of dependence, motivation, and attempts to quit smoking in the German population. Methods: Cross-sectional analysis of data...
Article
Background: Heated tobacco products (HTPs) are designed to heat tobacco to a high enough temperature to release aerosol, without burning it or producing smoke. They differ from e-cigarettes because they heat tobacco leaf/sheet rather than a liquid. Companies who make HTPs claim they produce fewer harmful chemicals than conventional cigarettes. Som...

Smoking increases cardiovascular disease (CVD) risk by leading to endothelial injury. E-cigarettes remain a popular way to stop smoking. Evidence on their effect on cardiovascular health is growing but remains limited, particularly in the short-term. The main objective of this study was to compare short-term cardiovascular effects in smokers who qu...

Introduction: E-cigarettes (ECs) may benefit smokers with mental health conditions who are more likely to smoke, and smoke more heavily, than those without mental health conditions. This could be undermined if harm misperceptions in this group are high as is the case in the general population. This study aimed to assess EC harm perceptions relativ...

Introduction In England, the use of electronic cigarettes as a smoking cessation aid has become more popular than any other aid. Previous research suggests that ex-smokers from lower social groups are more likely to use e-cigarettes compared to ex-smokers from more socially advantaged groups. The present study aimed to assess the association betwee...

Background: Most smokers attempting to quit relapse. There is little evidence whether the use of e-cigarettes ('vaping') increases or decreases relapse. This study aimed to assess 1) whether vaping predicted relapse among ex-smokers, and 2) among ex-smokers who vaped, whether vaping characteristics predicted relapse. Methods: Longitudinal web-ba...
