12 Senators ask FDA for details on ecig premarket review process

September 9, 2020 was the deadline for e-cigarette companies to submit their applications for premarket review to the FDA, a so-called premarket tobacco product application (PMTA). To date, FDA has approved a few PMTAs, most notably for Philip Morris’ IQOS heated tobacco product. The process has not been transparent and health groups and a publicContinue reading “12 Senators ask FDA for details on ecig premarket review process”

Good news: Youth e-cig use dropped in 2020

The CDC recently reported big drops in e-cigarette use between 2019 and 2020 (high school dropped from 27.5% to 19.6% and middle school dropped from 10.5% to 4.7%). As the figure above (courtesy of CDC.) shows, however, e-cig use is still very high, way above where cigarette smoking and e-cigarette use were nine years earlierContinue reading “Good news: Youth e-cig use dropped in 2020”

Congress extends ban on mailing cigs to include all e-cigs, including marijuana vapes

The recent legislation Congress passed to fund the government included a provision extending the PACT Act’s prohibition on sending cigarettes through the mail to include e-cigarettes. This will go a long way to closing down internet e-cigarette sales which, despite assurances from the e-cig companies and FDA, cannot be effectively age-gated. The law also requiresContinue reading “Congress extends ban on mailing cigs to include all e-cigs, including marijuana vapes”

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”
