We know a lot about how e-cigarettes cause disease

The evidence on the health effects of e-cigarettes was the subject of two recently published reviews that focus on cardiovascular, pulmonary and immunologic effects of e-cigarettes. These reviews complement earlier reviews on the pulmonary effects of e-cigarettes, e-cigarettes and smoking cessation, and the gateway effect for smoking among youth and young adults. Taken together theseContinue reading “We know a lot about how e-cigarettes cause disease”

More evidence that dual use is worse than smoking

Krisha Reddy and colleagues just published “ Respiratory Symptom Incidence Among People Using Electronic Cigarettes, Combustible Tobacco, or Both” in American Journal of Respiratory and Critical Care Medicine that showed that dual use of e-cigarettes and cigarettes doubled the odds of developing respiratory symptoms (aOR 2.22, 95% CI 1.79-2.75). This was a statistically significantly biggerContinue reading “More evidence that dual use is worse than smoking”

E-cig use associated with asthma, COPD in never-smokers

One of the excuses that e-cigarette advocates have used to dismiss the papers linking e-cigarette use with lung disease — that most e-cigarette users are current or former smokers — just got blown away with publication of a new study by Emine Bircan and colleagues of the association between e-cigarette use and lung disease inContinue reading “E-cig use associated with asthma, COPD in never-smokers”

The biological evidence of e-cig dangers keeps piling up

Rachel Keith and Aruni Bhatnagar just published “Cardiorespiratory and Immunologic Effects of Electronic Cigarettes,” which is a nice overview of the growing biological evidence base that e-cigarettes have a lot of adverse health effects, many similar to cigarettes. This material is particularly important because the people who continue to promote e-cigarettes for “harm reduction” continueContinue reading “The biological evidence of e-cig dangers keeps piling up”

Three years later the NASEM report on e-cigs is out of date

Physicians for a Smokefree Canada just released this blog post which is an excellent summary of how the state of knowledge has advanced substantially since the National Academies of Science, Engineering and Medicine released its report on e-cigarettes in 2018. While the report was a good summary of the evidence when it was prepared, weContinue reading “Three years later the NASEM report on e-cigs is out of date”

More evidence that e-cigs damage lung health independent of smoking

Wubn Xie and colleagues just published another well-done study showing that e-cigarette use (current and past) increases risk of lung disease by about 30%-70% even after taking any current or past smoking in to account. They used 4 years of the large Population Assessment of Tobacco and Health (PATH) study that follows people over time.Continue reading “More evidence that e-cigs damage lung health independent of smoking”

Broad range of studies show e-cigs increase lung disease risk by 40-50%

Thomas A. Wills and colleagues just published “E-cigarette Use and Respiratory Disorder: An Integrative Review of Converging Evidence from Epidemiological and Laboratory Studies” in European Respiratory Journal that, as the title indicates, sums up the evidence linking e-cigarette use with respiratory disease epidemiological studies of the population as a whole as well as briefly summarizingContinue reading “Broad range of studies show e-cigs increase lung disease risk by 40-50%”

Major EU scientific committee highlights e-cig dangers, gateway effect

On 23 September 2020, the European Commissions’ Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) issued its Preliminary Opinion on electronic cigarettes  at a request from the Commission “to assist the Commission in assessing the most recent scientific and technical information on e-cigarettes. Findings presented in the scientific opinion will feed into the Commission’sContinue reading “Major EU scientific committee highlights e-cig dangers, gateway effect”
