  • Study Violates Ethical Principles of Research Conduct
    Michael B. Siegel

    NOT PEER REVIEWED This study violates basic ethical principles of research conduct because it exposes children to unreasonable and unnecessary risks, intentionally encourages parents to put their children at risk, and fails to incorporate alternative methods that would reduce these risks.

    The Helsinki declaration states that:

    "The benefits, risks, burdens and effectiveness of a new intervention must be...

  • Genetic susceptibility testing to lung cancer and outcomes for smokers
    Robert P Young

    NOT PEER REVIEWED We wish to comment on the findings of Smerecnik et al.1 with respect to significant advances in genetic testing , which are highly relevant to their review. Unlike the early single genetic marker tests analysed by Smerecnik et al.,1 where subjects are dichotomised to positive or negative results, genetic susceptibility tests for lung cancer are now multivariate risk tests.2 These new risk tests incorpora...

  • Are changes in functional beliefs about smoking a proxy for nicotine withdrawal symptom reduction?
    Gillian S Gould

    NOT PEER REVIEWED Fotuhi et al concluded in their interesting study of patterns in smokers' cognitive dissonance-reducing beliefs that rationalisations about smoking change systematically with changes in smoking behaviour(1). Moreover, they argue that: i) changes in attitude on quitting are higher for 'functional' beliefs rather than 'risk-minimising' beliefs and ii) if smokers relapse these functional beliefs return to p...

  • Brazil's COP4 Delegation disagrees with the conclusions of the research paper "Tobacco industry's fight ITGA FCTC Implementation in the Uruguay negotiations"
    Tania Maria Cavalcante

    The author seeks to analyze the interference of the International Tobacco Growers Association (ITGA) in the decisions of the 4th Conference of the Parties (COP 4) on the Framework Convention on Tobacco Control (FCTC) regarding Guidelines recommending the prohibition of additives in cigarettes and includes Brazil as one of the countries influenced by this organization. As members of the Brazilian del...

  • Corrections to citations and interpretation of Hughes, et al
    John R Hughes

    I would like to make one correction and some comments on this article's interpretations of our prior review article on hardening (Drug Alcohol Dependence 117:111-17, 2011).

    The Cohen et al article cites the prior review as treating "tobacco control policies solely as a driver of quit attempts, with no impact on the ability to maintain abstinence after a quit attempt (p 266)." The article actually stated "...

  • Limited Sampling and lack of social group can effect the comparison of cigarette- and hookah-related videos on YouTube
    Atif A Baig

    NOT PEER REVIEWED We want to share our thoughts regarding the conclusions of this comparison. We strongly believe that this research must be evaluated with a larger sample. The criteria for inclusion or exclusion need to be revised, for two reasons:

    1. If we search for videos on Youtube using the words "cigarette" or "hookah", there are more than 86,500 and 39,850 videos respectively (search dated, March 15th, 201...

  • Free NRT by mail an intent-to-treat defeat
    John R. Polito

    Zawertailo, Selby and colleagues conclusion that free replacement nicotine (NRT) by mail is effective is deeply disturbing.[1] While the study's free abstract portrays free NRT by mail as a resounding success (21.4% smoking cessation at 6 months versus 11.6% for no-intervention), it neglects mention that under intent-to-treat analysis that there was zero benefit over no-intervention (an average of 8.7 percent 30-day poi...

  • Response to Thomson et al.
    Michael S. Givel
    NOT PEER REVIEWED I note this article in Tobacco Control quotes my two recent articles on the Bhutanese endgame. However, the Tobacco Control article to a certain degree does not catch the spirit of what is going on in Bhutan and what I concluded in my publications. Importation of small amounts of tobacco for personal consumption is legal. Sales are not--they are banned nationwide. Nevertheless, there is a major tobacco black mark...

  • What are U.S. health officials smoking?
    John R. Polito

    NOT PEER REVIEWED Zhu and colleagues' population level findings contribute to a growing body of external real-world evidence supporting the conclusion that the quitting product marketing industry's "double your chances" mantra is false and deceptive, and that smoker reliance upon it is likely responsible for a host of negative consequences, including failure to quit and premature demise.[1]

    Their review of twenty years...

  • Authors' Response
    Hillel R. Alpert

    The volume of attention to our study in the U.S. and international press is not surprising, considering the widespread promotion of nicotine replacement products to all smokers in the population, and their growing inclusion in government subsidized health plans. Prior to addressing criticisms made by Stapleton and others, we note that their comments reflect at least one important area of agreement. The fact that no adva...
