  • More to e-cigarettes than meets the eye?

    NOT PEER REVIEWED The United Kingdom government is now recommending e-cigarettes as important tools in helping individuals to quit smoking (http://www.bbc.co.uk/news/health-41339790). It is widely acknowledged that, for many, smoking tobacco is detrimental to health. However, it is perhaps less widely appreciated that we have only a limited understanding of why smoking tobacco is bad for our health. Why, for example, might you be 40 times more likely of succumbing to lung cancer if you are a persistent heavy smoker? What is it in tobacco or in the act of smoking which is damaging to health? These are the enigmas of smoking tobacco which have remained largely unanswered. We are interested in the myriad ways that humans are exposed to aluminium in everyday life (http://pubs.rsc.org/en/content/articlepdf/2013/em/c3em00374d). Intriguingly one such way is smoking tobacco and the main reason for this is the presence of significant amounts of aluminium in tobacco (http://www.amjmed.com/article/S0002-9343(05)00710-2/pdf).When tobacco is smoked its components form an aerosol which is taken down into the lung before it is eventually expired. Anyone who has set up a ‘smoking machine’ to investigate this will no doubt have been impressed by the efficiency with which a surrogate lung fluid transforms th...

  • E-cigarettes & sociodemographic considerations

    NOT PEER REVIEWED The authors point out that rates of adolescent ever use of e-cigarettes are substantial and increasing, but rates of regular use remain low. Yet it is also worth placing these rates of adolescent use in the context of other groups of e-cigarette users. In particular, a recent systematic review colleagues and I published into sociodemographic differences in e-cigarette use gives further salience to Conner et al’s findings. Although the availability of UK evidence for our review was limited, some very clear patterns emerged internationally. For instance, within the 38 studies reporting ever use and the 22 reporting current use, these outcomes were particularly prevalent in older adolescents and younger adults (versus younger children and older adults respectively). This therefore lends further weight to Conner et al’s recommendations around regulating the marketing and sale of e-cigarettes to minors in countries which lack sufficient legislation in this area. Both papers also show the importance of future studies stratifying findings by sociodemographic variables such as age to ensure more subgroup analyses are possible.

  • Misinterpretation of prevalence estimates from Japan

    NOT PEER REVIEWED In the second column of this article, the author describes findings from a survey in Japan (Tabuchi et al, 2016, reference 15). However, there is a misinterpretation of Tabuchi et al’s table 2 which leads to wrong percentages for having tried heat not burn products in Caputi’s article. The figures 8.4% and 7.8% are not the percentages who had ever tried these products in the population but instead percentages out of those respondents who had ever tried an e-cigarette or a heat not burn product.

    The actual figures for the population are therefore about 0.6% for iQOS (8.4% of 6.6%) and 0.5% for Ploom (7.8% of 6.6%).

    Further information on the ever use of different products by age, gender and smoking status (about 1% of 15-19 year olds had tried each of the two heat not burn products), is found in supplementary table 3 of Tabuchi et al.

  • Study on flavours in NYC tobacco products is misleading on preemption

    NOT PEER REVIEWED
    Without citing any sources or providing any related analysis or explanation, this paper makes several sloppy and misleading statements about the scope and impact of federal preemption relating to state and local restrictions of flavored tobacco products.

    We know from the preemption provisions in the federal Tobacco Control Act that state and local governments may not regulate the ingredients or characteristics of a tobacco product if the state or local regulation is “different from, or in addition to” an FDA tobacco product standard. [Sec. 916(a)(2)] But we do not yet know how FDA or the courts will interpret or apply that “different from, or in addition to” phrase. For example, it could mean that state and local governments are free to prohibit or limit the use of certain flavorings in certain types of tobacco products unless or until FDA prohibits or limits flavorings for those same types of tobacco products. To assert and publish a more restrictive interpretation of federal preemption with no qualification or clarification is not only misleading but promotes a more restrictive interpretation than necessary or desirable.

    The paper also fails to note that the courts have ruled that the Tobacco Control Act’s preemption provisions leave state and local governments free to restrict the sale of flavored tobacco products within their boundaries. [See, e.g., U.S. Smokeless Tobacco v. City of New York, 708 F.3d 428 (2nd Cir., 2013).] The...

  • E-cigarettes: The Indian Perspective

    NOT PEER REVIEWED
    Background
    E-cigarette is a delusive name for what the product actually is; an electronic vaporization device. Basic parts of an e-cigarette include: a tank containing the liquid to be vaporized, some sort of heating element, a battery to power the device, and a mouth piece. The liquid, often referred to as e-liquid, usually contains a base (for production of thick vapor) and flavor. E-liquid may or may not contain nicotine. The heating element converts the e-liquid into aerosol, which is then inhaled by the user. While many models resemble a conventional cigarette, others look nothing alike. Colloquially referred to vaporizers, such models have become more common in the recent years.
    In the western world e cigarettes proposed as a tobacco control strategy for possible nicotine reduction and stressed on policy appraisals of harm and safety on regulation of other ingredients of the products. The related conflicts and controversies of e cigarettes as a contemporary tobacco control are discussed (1).
    E-cigarettes began to appear in the Indian market around 2010. Today, E-cigarettes pose a complex challenge for the tobacco stricken country. According to Global Adult Tobacco Survey (GATS) 2010, 34.6% of the Indian adults were current tobacco users with 14% of adults indulging in current tobacco smoking (5.7% current cigarette smokers, 9.2% current bidi smokers) (2). Global Youth Tobacco Survey (GYTS) 2009 estimated current toba...

  • Blogging is a good practice for accessibility

    NOT PEER REVIEWED
    The editors of this journal, Tobacco Control, and specifically the authors of the editorial “Blog fog? Using rapid response to advance science and promote debate” [1] highlight the need - or requirement, depending on the viewpoint - of utilising a specified platform to debate the finer points of an article.

    From an academic standpoint, individuals that have an interest in a specific field of study - such as Tobacco Control - will see, and respond to, such articles in the appropriate manner. However, one of the pitfalls prevalent in any rapid response platform, and this isn’t limited to the journal Tobacco Control, is the necessity of the journal’s guidelines to adhere to a specific writing format. This does have some advantages in keeping the debate over an article related exclusively to the article. However, there are some respondents that prefer to write an unabridged version of a critique lest the comment not pass the rapid response system for publication.

    There are several advantages to publishing a critique of an article outside the rapid response system [2] that allows for a broader audience to read and respond to both the article content and the critique.

    Personal blogs often reflect the style of the author, and also allow for greater freedom of expression including the use of imagery to illustrate vital points that many readers find both enjoyable and informative.

    Providing a platform within the journal must allo...

  • Good case for subsidies

    NOT PEER REVIEWED This seems a good case for encouraging rechargeable cigalikes and 3rd generation refillable systems in the locations that charge a low cigarette tax.

    Time for subsidies?

  • Chairperson New Nicotine Alliance Sweden/Press Officer INNCO.org

    This is a test message to ascertain if BMJ and Tobacco Control have gotten the rapid response feature up and running. If so this message should appear and those scientists globally wanting to file responses will be immediately alerted that this is now possible. The essence of any critique I personally may have with the BlogFog article is summarized in my declarations of intellectual COI. Submitted March 2nd, 2017.

  • Disappointing retreat from the public square

    NOT PEER REVIEWED
    The editors of this journal, Tobacco Control, argue in their blog that debate about published articles should be concentrated on their rapid reaction facility. It is possible that they are making a constructive invitation to their critics to join a debating platform they might otherwise be wary of. However, the blog has been widely read as disparagement of other forms of engagement, notably social media and blogs. It is possible that the editors do not fully appreciate why people use blogs and social media to respond to papers they find problematic, and not Tobacco Control's rapid response feature. Here are several reasons:

    1. Trust

    Critics may consider, rightly or wrongly, that Tobacco Control has a track record of publishing papers that have dubious scientific merit, overconfident conclusions and policy recommendations that cannot be supported by the paper - almost always reinforcing a particular (abstinence-only) perspective. Critics may be concerned that their work will be treated unfairly or sidelined, or that they will be judged or ridiculed. They may distrust the editors, believe the journal is not impartial, or hold it in low esteem.

    2. Conflict of interest and incentives

    Not everyone is content to have their reactions edited or approved by the same people whose work they are criticising. Once a journal has published an article that is open to criticism, it develops a conflict of interest between its own r...

  • Request for a few important clarifications

    NOT PEER REVIEWED The authors of this editorial assert that a journal article’s authors are “entitled to be aware of and respond to critiques”, and imply that this is only possible if critiques appear in a forum attached to the journal. Setting aside the fact that authors can easily become aware of and respond to critiques on other forums, I am curious if the authors could offer some basis for claiming such an entitlement? It seems quite contrary to all existing laws, principles of ethics, cultural norms, and standard practices that relate to commentary about published work. Moreover the behavior of many of these very authors suggests they are willing to go to great lengths to avoid being made aware of critiques.

    It seems safe interpret the statement as saying that at least these particular authors would like responses to their work to appear on this page. And so, I am fulfilling their request. (Assuming this is allowed to appear, that is. I say that not because I believe there is anything in this comment that would warrant censorship, but to emphasize the blindness of this process. That is, the commentator really has no idea what will be allowed to appear.) I call the authors’ attention to two blog posts I have written critiquing this editorial to ensure they have the requested opportunity to be aware: https://antithrlies.com/2017/02/20/editors-of-t...
