E-cig science has marched on; it is important that decision making and education be based on the current state of knowledge

In January 2021, I published a blog post making the point that the 2018 National Academy of Science Engineering and Medicine (NASEM) report on e-cigarettes was out of date. Now, Physicians for a Smoke Free Canada has published an extensive update detailing specifically how the science on e-cigarettes has advanced since then 2018, noting thatContinue reading “E-cig science has marched on; it is important that decision making and education be based on the current state of knowledge”

The e-cig gateway has two doors

When people talk about the “gateway effect” of e-cigarettes, they are usually referring to the first gateway: the fact that never-smoking kids who initiate nicotine use with e-cigarettes are more likely to start smoking cigarettes than youth who never try e-cigarettes. E-cig enthusiasts dismiss these studies by invoking the “common liability” theory which asserts thatContinue reading “The e-cig gateway has two doors”

Ecig enthusiasts respond to criticism that they selectively cited the science by ignoring the conclusions of the papers they do cite

In addition to the excellent paper by Samet and Barrington-Trimis the American Journal of Public Health recently published two letters to the editor — one from Wasim Maziak and one from me — criticizing the paper “Balancing consideration of the risks and benefits of e-cigarettes.” That paper argues that concerns over youth e-cigarette use needsContinue reading “Ecig enthusiasts respond to criticism that they selectively cited the science by ignoring the conclusions of the papers they do cite”

Youth smoking and vaping growing in e-cig friendly New Zealand

New Zealand, like England, the US FDA, and a few other countries, has embraced e-cigarettes. Like other e-cig enthusiasts, the Health Ministry minimizes risks to kids. In particular, its “Position statement on vaping” says: There is no international evidence that vaping products are undermining the long-term decline in cigarette smoking among adults and youth, andContinue reading “Youth smoking and vaping growing in e-cig friendly New Zealand”

Science FDA (and everyone else) needs to actively engage as they think about whether to authorize Juul and the other ecigs

When I read the FDA’s Technical Project Lead summary of its scientific justification for authorizing the sale of RJ Reynolds’ Vuse Solo e-cigarette, I was struck by the fact that it ignored the broad scientific literature on e-cigarettes and seemed to accept industry-framed arguments. For example: They ignored the evidence that as consumer products, e-cigarettesContinue reading “Science FDA (and everyone else) needs to actively engage as they think about whether to authorize Juul and the other ecigs”

Even more evidence that youth who start with e-cigs triple the odds that they will later smoke cigarettes

As more studies are published on the link between youth e-cigarette use and subsequent cigarette smoking youth, people continue publish meta-analyses summing up the results. The latest such meta-analysis, recently published in PLOS One by Sze Lin Yoong and colleagues, “Association between electronic nicotine delivery systems and electronic non-nicotine delivery systems with initiation of tobaccoContinue reading “Even more evidence that youth who start with e-cigs triple the odds that they will later smoke cigarettes”

New studies for UK, Netherlands and Flanders and US confirm gateway effects of e-cigs to combusted tobacco products

Three new studies add to the already overwhelming case that e-cigarettes are a gateway to combusted product use; two of these studies also show that combusted tobacco use predicts later e-cigarette use among youth. These studies are benefit from the fact that the data were collected relatively recently, which is important because e-cigarette technology isContinue reading “New studies for UK, Netherlands and Flanders and US confirm gateway effects of e-cigs to combusted tobacco products”

New WHO report highlights falling cigarette use and challenges that new tobacco products pose to public health and implementation of the FCTC

On July 27, 2021 the WHO released the WHO report on the global tobacco epidemic 2021: addressing new and emerging products, its eighth such report. The good news is that it documents solid progress in reducing tobacco use. After over a century of growth, “between 2007 and 2019, smoking rates decreased from a global averageContinue reading “New WHO report highlights falling cigarette use and challenges that new tobacco products pose to public health and implementation of the FCTC”

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”
