E-cigs as consumer products don’t help smokers quit

Richard Wang, Sudha Bhadriraju and I just published a comprehensive meta-analysis of the association between e-cigarette use and smoking cessation, “E-Cigarette Use and Adult Cigarette Smoking Cessation: A Meta-Analysis,” in American Journal of Public Health. Unlisk earlier meta-analyses, we made a distinction between population observational studies, which are valuable for assessing the effects of e-cigarettesContinue reading “E-cigs as consumer products don’t help smokers quit”

COVID-19 incidence and death correlated with vaping across states

There is a robust literature showing that e-cigarette use damages lung function and compromises immune function in the respiratory system, which makes it reasonable to expect that e-cigarette use would be associated with more COVID-19 infections and deaths. So far, there has been one study (in youth and young adults) showing increased risk of developingContinue reading “COVID-19 incidence and death correlated with vaping across states”

More evidence that e-cigs expanding nicotine addiction

Since the introduction of e-cigarettes to the U.S. market, use has increased rapidly among youth. Some have argued that, while not optimal, this increase represents kids who would otherwise have smoked cigarettes. In particular, Levy et al (Levy et al., 2017, Levy et al. 2018) concluded that the decline in U.S. youth cigarette smoking acceleratedContinue reading “More evidence that e-cigs expanding nicotine addiction”

Juul delivers less of an important carcinogen than cigs

Kim Pulvers and colleagues recently published “Effect of Pod e-Cigarettes vs Cigarettes on Carcinogen Exposure Among African American and Latinx Smokers,” a well-done randomized controlled trial that demonstrated that African American and Latinx smokers who switched from cigarettes to Juul for 6 weeks had substantially lower levels of the lung carcinogen NNAL in their urine.Continue reading “Juul delivers less of an important carcinogen than cigs”

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”

Ordinance to make multi-unit housing in San Francisco (tobacco) smokefree advances

Today the Public Safety and Neighborhood Services Committee unanimously forwarded an ordinance to the full Board of Supervisors (the City’s legislative body) to make buildings with 3 or more housing units smokefree. The public commenters strongly supported the ordinance with cogent stories about how they and their families were suffering from secondhand smoke drifting inContinue reading “Ordinance to make multi-unit housing in San Francisco (tobacco) smokefree advances”

If e-cigs are effective cessation aids, when will an e-cig company submit the needed evidence for FDA approval?

JAMA just published another randomized controlled trial, “Effect of e-cigarettes plus counseling vs counseling one on smoking cessation,” that found that giving smokers who were motivated to quit free NJOY e-cigs for 12 weeks together with intensive counseling led to significantly more quitting at 12 weeks than counseling alone. The effect faded by 24 weeks,Continue reading “If e-cigs are effective cessation aids, when will an e-cig company submit the needed evidence for FDA approval?”

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”

Evidence supporting banning menthol keeps piling up, making it even more of a social issue

Nicotine and Tobacco Research recently published four papers on menthol (menthol preference associated with greater nicotine dependence and greater urge reduction after smoking, biological effects of menthol on addiction. menthol use has not dropped among Black and Hispanic students, 85% of pregnant women smoke menthol and quit less) adding to the already-compelling case that mentholContinue reading “Evidence supporting banning menthol keeps piling up, making it even more of a social issue”
