Laws to limit tobacco smoke exposure in the workplace are overall effective, but people in some occupations still face high exposure, according to a new study.


The study, presented at the annual meeting of the American Public Health Association[1] , looked at occupational environmental smoke exposure[2] before and after the 2004 Smoke-Free Workplace Law went into effect in Massachusetts. It showed that workplace exposure decreased to 5.4 percent in 2010, from 8 percent in 2003.


However, the study also showed that workers in certain occupations still faced high rates of exposure to secondhand smoke at work. For instance, 37.4 percent of workers in the repair, maintenance and installation industries reported being exposed to tobacco smoke at work. And 22.6 percent of workers in the transportation industries, while 19.8 percent of people in material moving industries reported tobacco smoke exposure at work.


"We're seeing a steady decline in prevalence of exposure[3] , but it's clear that there are still specific groups of workers that deserve our attention. Findings like these that combine information about occupation and environmental tobacco smoke provide helpful information for evaluating comprehensive statewide smoke-free workplace laws and for targeting interventions to reduce risks," study researcher Kathleen Fitzsimmons, MPH, of the Occupational Health Surveillance Program at the Massachusetts Department of Public Health, said in a statement.


In addition, Fitzsimmons and her coauthors found that male, non-white and younger workers were more at risk for tobacco smoke exposure.

  • You'll Be Less Anxious


    Even though smokers may believe taking a long drag on a cigarette can help to calm nerves, a British study published earlier this year suggests that <em>quitting</em> can actually decrease anxiety more over the long-term. "People who achieve abstinence experience a <a href="http://www.cbc.ca/news/health/story/2013/01/02/smoking-quit-anxiety.html">marked reduction in anxiety</a> whereas those who fail to quit experience a modest increase in the long term," researchers wrote in the British Journal of Psychiatry study, as reported by CBC News. Similarly, a 2010 study in the journal Addiction showed that <a href="http://www.reuters.com/article/2010/06/17/us-smoking-idUSTRE65G0CX20100617">perceived stress decreased</a> for people who quit smoking for a year after hospitalization for heart disease, Reuters reported.

WebMD points out that smoking <a href="http://www.webmd.com/smoking-cessation/ss/slideshow-ways-smoking-affects-looks">affects skin tone</a>, promotes sagginess and, of course, causes those wrinkles around the lip area. However, the American Society for Aesthetic Plastic Surgery notes that just a month-and-a-half after <a href="http://www.surgery.org/consumers/plastic-surgery-news-briefs/skin-quit-smoking-1031403">quitting smoking</a>, your skin will already begin to look better.




  • You'll Have More Locks


    If you love your hair, maybe it's time to put the cigarettes down. Research has linked smoking with an increased risk of male pattern baldness. BBC News reported in 2007 on a Archives of Dermatology study, showing even after taking into account other hair-loss risk factors like age and race, <a href="http://news.bbc.co.uk/2/hi/health/5413382.stm">heavy smoking</a> (at least 20 cigarettes daily) raised the risk of baldness. And a 2011 study showed that smoking, stress, drinking and genes were all<a href="http://www.webmd.com/skin-problems-and-treatments/hair-loss/news/20110923/divorce-heavy-drinking-smoking-linked-to-hair-loss"> risk factors for baldness</a>, WebMD reported.




  • Your Mood Will Improve


    Here's a pretty good benefit: Stopping smoking could <a href="http://news.brown.edu/pressreleases/2010/12/smoking">make you a happier person</a>, according to research from Brown University. Researchers there found that smokers were <a href="http://news.brown.edu/pressreleases/2010/12/smoking">never happier</a> than when they were quitting smoking, even if they went back to smoking afterward. According to a <a href="http://news.brown.edu/pressreleases/2010/12/smoking">news release</a>: <blockquote> The most illustrative — and somewhat tragic — subjects were the ones who only quit temporarily. Their moods were clearly brightest at the checkups when they were abstinent. After going back to smoking, their mood darkened, in some cases to higher levels of sadness than before.</blockquote>




  • You'll Have More Birthdays


    Stopping smoking may <a href="http://www.huffingtonpost.com/2012/10/29/women-stop-smoking-live-10-years-longer_n_2011804.html">help women live a decade longer</a> than they would have if they had continued lighting up, according to a 2012 study in The Lancet. Researchers also found that the more the women smoked, the higher their risk of premature death, with even "light" smokers (those who smoked just one to nine cigarettes a day) having a doubled risk of death compared with non-smokers. "If women smoke like men, they die like men -- but, whether they are men or women, smokers who stop before reaching middle age will on average <a href="http://www.eurekalert.org/pub_releases/2012-10/l-soa102312.php">gain about an extra ten years of life</a>," study researcher Professor Sir Richard Peto, of the University of Oxford, said in a statement.




  • You'll Improve Your Pregnancy Chances

    If you <a href="http://abcnews.go.com/Health/Healthday/story?id=8427779#.UOsAFInjlU4">don't like bland food</a>, then don't smoke, research suggests.

  • Your Colds Won't Be As Bad


    Mild cold symptoms could take on a more serious form for smokers, according to a study from Yale University researchers. The findings, published in 2008 in the Journal of Clinical Investigation, showed an <a href="http://news.yale.edu/2008/07/24/study-shows-why-cigarette-smoke-makes-flu-other-viral-infections-worse">overreaction of the immune systems</a> of cigarette smoke-exposed mice when exposed to a virus similar to the flu. "The anti-viral responses in the cigarette smoke exposed mice were not only not defective, but were hyperactive," study researcher Dr. Jack A. Elias, M.D., said in a statement. "These findings suggest that smokers do not get in trouble because they can't clear or<a href="http://news.yale.edu/2008/07/24/study-shows-why-cigarette-smoke-makes-flu-other-viral-infections-worse"> fight off the virus</a>; they get in trouble because they overreact to it."
