  • Methodological pitfalls in the measurement and decomposition of socioeconomic inequality of smoke exposure
    Guido Erreygers
    NOT PEER REVIEWED I would like to point out a few disturbing inaccuracies in the methodology and interpretation. Since the health variable is binary, the authors apply "Wagstaff's correction" to the Concentration Index. This is a perfectly legitimate decision, but the authors mistakenly suggest that this correction can be applied to both the relative and the absolute version of the index, yielding two normalized indices. In fact,...

  • Flavor Profiles
    Kenneth H Kawa

    NOT PEER REVIEWED When it comes to vaping my knowledge is somewhat advanced, in the hardware aspect I am in the forefront of technology, I test prototypes and beta models for manufacturers all around the globe, I also have acquired quite a bit of knowledge when it comes to the creation of flavors.

    There's a big difference between something you like and what is referred to an "All Day Vape" or ADV and the impact t...

  • This is a perspective through a warped lens.

    NOT PEER REVIEWED
    This is not a particularly well constructed argument. In particular, the paragraph that states:
    "If ENDS emissions were really benign, indoor vaping advocates should take courage and call for it to be allowed in classrooms, crèches, hospitals and neonatal wards. That they do not rather suggests that they know well that such a position would be irresponsible."
    is possibly the worst excuse for a genuine point of debate it has ever been my misfortune to encounter. it is not even a particularly well constructed straw man.

    Many things are considered normal and appropriate for the general population that would not be considered appropriate for a crèche, classroom or neonatal ward.

    To use merely the first two examples that sprang to mind (and the list is almost endless):
    Incense sticks are widely used, and despite the clear emission of smoke, they are are not banned, or the subject of proposed bans, in most jurisdictions. Many people use them, but I doubt that any would do so in a crèche or neonatal ward. Yet, if we follow the same logic proposed here, this means that they are dangerous, and should be banned almost universally.
    Similarly, fog machines are widely used in stage shows, nightclubs and even teenage discos. Despite the extremely strong similarity with vaping, both in chemical composition and particle size, there are not widespread calls for fog machines to be banned (I'm certainly not aware of...

  • Bauld et al omit evidence on passive exposure to e-cigarette aerosol
    David W Bareham

    NOT PEER REVIEWED The American Indoor Hygiene Association (AIHA) i.e. Experts in in this particular field on passive exposure, have, previously, concluded conversely to Bauld et al (1). As they state:

    "If the only individual affected by using e-cigarettes were the vaper, the discussion could end here. That is not, however, the case. Similar to secondhand smoke, the ingredients exhaled by the vaper include nicot...

  • Indoor vaping and brochodilator use are not analogous
    Simon Chapman

    NOT PEER REVIEWED Bauld et al [1] draw an analogy between indoor vaping and the use of bronchodilators for asthma ("if and when vapour products with a medicinal license become available, it will be important to allow their use indoors, just as asthma inhalers, which dispense a drug and propellants into the atmosphere, can be used indoors.")

    Surely, they cannot be serious here?

    Newman et al showed the a...

  • Internet cigarette vendors make tax free claims and selling cigarette cheaper:An alarming isssue
    Md Abu Bashar

    NOT PEER REVIEWED The Internet is widely used source for purchasing and selling products. However,purchasing tobacco products online is a new trend. The internet vendors are often exempted from taxes leading to lowering the cost of cigarettes in certain countries.This is a really alarming situation as it would lead to increase in sales of tobacco products due to lower prices. Countries need to check this trend otherwise al...

  • Intent-to-treat analysis of observational studies assessing electronic cigarettes' efficacy as an aid to smoking cessation.
    Ivan Berlin

    NOT PEER REVIEWED In the last decade, electronic cigarettes (EC) have become increasingly popular in particular among smokers. Most EC users choose to use nicotine containing liquids (electronic nicotine delivery system, ENDS); these ENDS can be considered as similar to nicotine replacement therapies. Among the several questions EC use raises, one is of major importance: Are EC a smoking cessation aid and if yes to...

  • Impact of e-cigarette adverts on children's perceptions of smoking
    Deborah Arnott

    NOT PEER REVIEWED The study conducted in England by Petrescu and colleagues [1] concludes that there is a "potential for e-cigarette adverts to undermine tobacco control efforts by reducing a potential barrier (i.e. beliefs about harm) to occasional smoking". Clearly it is important to keep monitoring the impact of advertising, particularly on children, and this research paper is a welcome contribution. However, i...

  • Indoor air laws and hookah smoking
    Sandra S. Retzky
    NOT PEER REVIEWED.
    The authors rightly point out that loopholes exist in some smoke-free air laws, exempting smoking of ???tobacco-free or herbal hookah products??? in public places.
    In New York City, where this study took place, the governing laws are: (1) New York State Clean Indoor Air Act, and (2) New York City Smoke Free Air Act.[1] Between 2002-2003, both laws were amended to "prohibit smoking in virtually all in...

  • Addiction refuses to allow discussion of industry ties to criticism of our paper
    Margarete C. Kulik

    NOT PEER REVIEWED In June 2015 we published our paper "The smoking population in the USA and EU is softening not hardening" in the journal Tobacco Control. We showed that as smoking prevalence has declined over time, quit attempts increased in the USA and remained stable in Europe, US quit ratios increased (no data for EU), and consumption dropped in the USA and Europe. These results contradict the hardening hypothesis whi...
