  • Response to "Indoor exposure limits?"
    Sean Semple

    Dear Editor,

    We are grateful that the eLetter from Ms Cunnison provides an opportunity for us to clarify some aspects of our work [1].

    In the past there has been no authoritative guidance on the protection of public health from risks from particulate matter (PM) in indoor air. It is therefore a welcome development that the recent WHO Air Quality Guidelines for Indoor Air [2] concluded that there is no...

  • Theoretical and documented safety issues concerning electronic cigarettes
    Konstantinos E. Farsalinos

    NOT PEER REVIEWED In this interesting study by Cheah et al,1 the authors have raised several safety issues concerning electronic cigarettes. The majority of them were based either on the finding that nicotine content was inconsistent or that chemical constitution (for example glycols) may be hazardous to health.

    There is some inconsistency in characterizing polypropylene glycol as "a known irritant when inhaled o...

  • Indoor exposure limits?
    Belinda Cunnison
    I am a lay person, but curious as to how these conclusions are reached. How is it possible to describe 25 ug/m3 as a WHO _indoor_ air quality standard, when it seems to have been designed as an outdoor standard? More importantly how is it possible to apply the standard to journeys lasting under half an hour, when the standard specifically directs how to deal with short exposure times (http://www.epa.gov/ttn/caaa/t1/memoranda/pmf...

  • Re:Smoking imagery in movies requires action now
    Bobby j Burke

    Most of us know the people who control Hollywood. Well, the Movie Industry is controlled in a similar manner, by their Cousins. They assist in the production of the films by, having their cancer causing product portrayed as a natural thing that your favorite stars do, so why aren't you? Films should have NO tobacco products in them whatsoever!!! If I had my way, I'd stop all tobacco production. If You want to smoke, grow...

  • Tobacco industry efforts to influence health policies.
    Alain Braillon

    Smith et al provides us with a remarkable review of tobacco industry efforts to influence tobacco tax which deserves several comments.(1)

    First, such efforts can be quite successful as in France: From February 2004 to September 2012 there was no increase in tobacco taxes, accordingly cigarette sales remained unchanged and smoking prevalence of the youngest increased during Sarkozy's presidency, an exception amon...

  • 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
    NOT PEER REVIEWED

    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...
