Two more heart attack studies

As an addendum to the previous post, I should mention two more recent studies of smoking bans and heart attack rates. The first, from Brad Rodu, Nicholas Peiper and Philip Cole, published a couple months ago in Journal of Community Health, examines rates in six states and finds no effect:

The AMI mortality rate among persons age 45 + years (deaths per 100,000 persons, age-standardized to the 2000 US population) in the 3 years before adoption of the smoke-free ordinance (the expected rate) was compared with the rate observed in the first full year after the ban (the target year) in six US states. Target-year declines were also compared to those in states without smoking bans. Target-year declines in AMI mortality in California (2.0%), Utah (7.7%) and Delaware (8.1%) were not significantly different from the expected declines (P = 0.16, 0.43 and 0.89, respectively). In South Dakota AMI mortality increased 8.9% in the target year (P = 0.007). Both a 9% decline in Florida and a 12% decline in New York in the 2004 target year exceeded the expected declines (P = 0.04 and P < 0.0002, respectively) but were not significantly different (P = 0.55 and 0.08, respectively) from the 9.8% decline that year in the 44 states without bans. Smoke-free ordinances provide a healthy indoor environment, but their implementation in six states had little or no immediate measurable effect on AMI mortality.

The second unpublished study [pdf] looks at rates in 74 US cities that implemented smoking bans. It finds a decline of a mere 3% following implementation. Contrary to expectation, the effect disappears entirely when restricted to the 43 cities whose bans were meaningful. All things considered, it lends support to the idea that smoking bans have no short-term impact on heart attack rates.

  1. Jacob- perhaps your efforts would be better spent studying the correlation of smoking bans to the amount of money spent at dry cleaners.

  2. Perhaps youd better seek treatment for a series of mental issues Robert:

    The anti-smoking nazis PSYCHOSIS has been studied and found non-harmful and they can seek treatment!

    Idiopathic environmental intolerance: Part 1: A causation analysis applying Bradford Hill’s criteria to the toxicogenic theory.

    Idiopathic environmental intolerance (IEI) is a descriptor for a phenomenon that has many names including environmental illness, multiple chemical sensitivity and chemical intolerance. Toxicogenic and psychogenic theories have been proposed to explain IEI. This paper presents a causality analysis of the toxicogenic theory using Bradford Hill’s nine criteria (strength, consistency, specificity, temporality, biological gradient, biological plausibility, coherence, experimental intervention and analogy) and an additional criteria (reversibility) and reviews critically the scientific literature on the topic. The results of this analysis indicate that the toxicogenic theory fails all of these criteria. There is no convincing evidence to support the fundamental postulate that IEI has a toxic aetiology; the hypothesised biological processes and mechanisms are implausible.

  3. Jacob you busted their little world of delusional harm and their MADD!

    Im sure you can expect even more delusional comments from other nazi anti-smokers in tobacco control or even hit pieces on the net! These people are vile hateful individuals, check out Chris’s latest piece on vile internet comments from anti-smokers!

    Season of hate
    I generally have zero interest in what random people choose to type beneath the line of news stories on the internet, but a couple of articles this week made me think that the intellectual climate is darkening at a worrying rate.

  4. Take a quick survey and get good information on quitting smoking and not gaining weight! Google; quit smoking and lose weight. Lots of good information on how to avoid the pitfalls after you quit, like bloating, weight gain, constipation, etc.

  5. Bias Against Cold Turkey Quitting is Apparent in Literature; Possibly Influenced by Financial Conflicts of Interest?
    Imagine that you were doing a study on whether nicotine replacement therapy (NRT) is more effective than cold turkey quitting in smoking cessation. You ask a bunch of successful quitters (ex-smokers) and unsuccessful quitters (current smokers who have made a quit attempt) what strategy for smoking cessation they used in their most recent quit attempt. You might structure the question something like this:

    During your last quit attempt, what was the primary method you used to try to quit?
    1. NRT
    2. Buproprion
    3. Chantix
    4. Cold Turkey
    5. Other

  6. Perhaps the apparent bias is less astonishing when one finds out the rest of the story: The study was funded by the pharmaceutical industry.

    According to a background study document: “The Smoking Toolkit Study is currently funded
    by Cancer Research UK, Pfizer and GSK [GlaxoSmithKline].”

    Moreover, two of the researchers working on the Smoking Toolkit Study also have financial conflicts of interest with Big Pharma.

    As disclosed in a recent paper: “RW undertakes research and consultancy for the following developers and manufacturers of smoking cessation treatments; Pfizer, J&J, McNeil, GSK, Nabi, Novartis and Sanofi-Aventis. RW also has a share in the patent of a novel nicotine delivery device. AMC has received travel funding, honorariums and consultancy payments from manufacturers of smoking cessation products (Pfizer, J&J, McNeil, GSK, Nabi, Novartis and Sanofi-Aventis). He also receives payment for providing training to smoking cessation specialists; receives royalties from books on smoking cessation and has a share in a patent of a nicotine delivery device.”
