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”

What we can and cannot say about the immediate effect of SF’s flavored tobacco product ban

NOTE: This blog post was written before it came to light that the San Francisco data in the Friedman study was all collected before the flavor ban was being enforced. Without data after enforcement started, Friedman’s paper falls apart. Please read the recent blog post detailed why this is the case. On May 24, 2021Continue reading “What we can and cannot say about the immediate effect of SF’s flavored tobacco product ban”

Exposure to e-cigs in music videos associated with more e-cig use in real life

It has been well-established for over a decade that exposure to onscreen smoking in movies causes kids to smoke. Now, Anuja Majumundar and colleagues at USC have used similar methods as in the early movie studies to show that the more e-cig promotions young adults (age 18-24) see in music videos the more likely theyContinue reading “Exposure to e-cigs in music videos associated with more e-cig use in real life”

Lots of smoking in this year’s Oscar movies

2020 was a difficult year for everyone, including the movies, because of COVID-19. The Academy Awards have been delayed and many of the nominated films were released on video on demand rather than into theaters. As a result, some do not appear in the SFM “Top 10 box office” database.  We did review all the films thatContinue reading “Lots of smoking in this year’s Oscar movies”

Three years later the NASEM report on e-cigs is out of date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good summary of the evidence when it was prepared, weContinue reading “Three years later the NASEM report on e-cigs is out of date”

Youth e-cig use triples likelihood of daily cig smoking

The evidence that e-cigarettes are a gateway for smoking is strong and consistent. Now John Pierce and his colleagues have made that connection even stronger by showing that e-cigarette use strongly predicts daily cigarette smoking. (Previous studies measured current cigarette smoking, meaning in the past 30 days.) Their paper, “Use of E-cigarettes and Other TobaccoContinue reading “Youth e-cig use triples likelihood of daily cig smoking”

Lawsuit provides inside view of Foundation for a Smoke-Free World

The allegations in a wrongful termination lawsuit filed Lourdes Liz, the former Director of Digital and Social Media at the Foundation for a Smoke-Free World, provides specifics on how FSFW functions as an arm of Philip Morris International (sole funder of FSFW) and Alria, parent of Philip Morris Tobacco.

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”

FDA’s proposed guidance to industry on how to conduct product perception studies is a good start, but needs more specifics

My colleagues at the UCSF TCORS, in collaboration with Stanford, GSU and U of Iowa just submitted a public comment to FDA on its draft guidance on how tobacco companies should conduct perception studies of their products that are to be submitted to FDA as part of applications for approval to market these products orContinue reading “FDA’s proposed guidance to industry on how to conduct product perception studies is a good start, but needs more specifics”
