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”

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”

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”
