The Effects of Secondhand Smoke on Worker Health

November 4, 2014

More than 40 years after former U.S. Surgeon General Jesse Steinfeld first exposed the potential health risks of secondhand smoke (SHS) in 1971,1 and nearly 30 years after a subsequent Surgeon General’s report stated that SHS causes lung cancer and other diseases,2 all U.S. workers still do not have the right to breathe smoke-free air. In the late 1980s, 91.7 percent of Americans had an indicator of SHS exposure in their bloodstream3 and, at that time, only 3 percent of workers Smoke free workernationally reported a “no smoking” policy at their place of employment.4 Soon thereafter, laws prohibiting smoking in workplaces and other public venues began to be enacted at the local, state, and national levels to minimize the impact of SHS. In 2006 and again in 2010, two Surgeon Generals concluded unequivocally that there is no safe level of exposure to SHS.5 6

Today, smoke-free policies have effectively reduced the number of people exposed to SHS in the workplace.7,8,9,10 The proportion of nonsmokers with detectable levels of a SHS indicator has dropped to 40 percent.11 This level of exposure is still too high, and unfortunately, not all workers have the same level of protections. Currently, 65 percent of the U.S. population is covered by 100 percent smoke-free state or local smoke-free workplace laws, 77 percent is covered by 100
percent smoke-free restaurant laws, and 65 percent is covered by 100 percent smoke-free bar laws.12 However, only about half of the population (49 percent) is covered by 100 percent smoke-free laws covering all three of these types of venues.13

Hospitality Workers are at Higher Risk for SHS Exposure

The workplace is a major source of SHS exposure for adults, and SHS exposure in the workplace has been linked to an increased risk of heart disease and lung cancer among nonsmoking adults. Blue collar and service workers are more likely than white collar workers to be exposed to SHS at the workplace14 and are less likely to be covered by smoke-free policies.15,16

  • According to one study, prior to the implementation of a smoke-free law, employees working full-time in restaurants or bars that allowed indoor smoking were exposed to levels of air pollution 4.4 times higher than safe annual levels established by the U.S. Environmental Protection Agency (EPA) because of their occupational exposure to tobacco smoke pollution.17

Bartenders, servers, and casino workers are particularly unlikely to be protected by smoke-free policies and more likely to breathe SHS even when smoke-free policies are in effect.18,19 Without smoke-free laws, bars and lounges have among the highest concentrations of SHS of all public spaces – exposing bartenders to even greater levels of SHS than restaurant workers.20

  • When there are not smoke-free policies in effect, levels of SHS in bars are 3.9 to 6.1 times higher than levels measured at office worksites and up to 4.5 times higher than levels in homes with one or more smokers.21
  • Bartenders are more likely than many other workers to report eye, nose, or throat irritation or symptoms.22
  • A study examining the effects of SHS exposure in San Francisco, CA, restaurants and bars before the state’s smoke-free law took effect found that 74 percent of bartenders surveyed had respiratory symptoms (e.g., wheezing, cough, etc.), and 77 percent had sensory irritation symptoms (e.g. red, teary, or irritated eyes, runny nose, sneezing, sore or scratchy throat, etc.).23

Casino workers are exposed to high levels of SHS in the workplace and are at higher risk for developing SHS-related illnesses.

  • The National Institute for Occupational Safety and Health (NIOSH) conducted a health hazard evaluation at a casino in Atlantic City, NJ and found that workers had exceptionally high levels of a SHS exposure indicator in their bloodstreams.24 In particular, the study found generalized exposure to SHS throughout the entire gaming area. Casino workers who staffed nonsmoking tables did not have lower levels of SHS exposure than casino workers who staffed smoking tables.25
  • A study of nonsmokers’ exposure to SHS in Pennsylvania casinos found that smoke particles were 4 to 6 times greater inside casinos than outside, even with ventilation and few people smoking at the time.26 Additionally, the extent of SHS in the casinos was not confined only to the smoking areas.27

Smoke-Free Policies Improve Workers’ Health

Smoke-free policies reduce nicotine concentration levels and exposure to SHS in office and non-office worksites.28 Although SHS exposure declined among all worker groups between 1988 and 2002, the decline was greatest among blue collar and service workers, who experienced a 76 percent decline in a SHS indicator during that 14-year time period.29 Also during that time, the number of local 100 percent smoke-free ordinances in effect increased from 0 to 47
nationwide.30 There are now at least 1,159 localities and 36 states requiring 100 percent smoke-free workplaces, restaurants, or bars, of which 673 localities and 24 states laws cover all three of these types of venues.31

The evidence shows that implementing smoke-free policies has immediate benefits for restaurant and bar workers’ health. The Surgeon General reports that in high-risk settings such as bars, smoke-free policies can lead to reductions of 80-90 percent of SHS exposure.32 Additional studies examining the impact of specific smoke-free laws have similar findings:

  • In Wisconsin, three to six months after the implementation of the statewide smoke-free law, nonsmoking bar workers experienced a significant improvement in respiratory health.33
  • The percentage of hospitality workers exposed to SHS declined from 91 percent to 14 percent in just a single year after New York’s smoke-free law went into effect. The amount of time that hospitality workers were exposed to SHS on the job decreased by 98 percent—from 12.1 hours to 0.2 hours.34 Reports of one or more sensory symptoms—affecting the eyes, nose, or throat—declined from 88 percent to 38 percent just one year after the smoke-free law took effect. 35
  • Nonsmoking bar and restaurant employees in Oregon communities without smoke-free laws had higher levels of a tobacco-specific lung carcinogen than similar workers in communities with a smoke-free law in effect. Workers in communities without smoke-free laws also had higher levels of the carcinogen after their work shift than they did previously.36
  • A study of Minnesota hospitality workers showed that after implementation of a smoke-free law, concentrations of a SHS indicator in the bloodstream decreased by more than 50 percent in a majority of workers.37

Smoke-free laws also prompt many smokers to quit.

  • During the three months following the passage of Nebraska’s smoke-free law, 16 percent of callers to the state’s Quitline said that they were influenced to call as a result of the smoke-free law.38
  • A recent study found that Kentucky counties with smoke-free laws had higher quitline call rates and lower smoking rates than counties without smoke-free laws. In fact, individuals in communities with smoke-free laws were 18% less likely to smoke.39
  • The Community Preventive Services Task Force attributed a 2.7 reduction in overall tobacco use in the US between 2009 and 2011 to smoke free laws. 40

Smoke-free policies reduce long-term risk of lung cancer and cardiovascular disease among workers and patrons alike.

  • Passage of a comprehensive smoke-free law is associated with lower rates of hospitalizations and death from heart attacks, heart disease, strokes, and respiratory diseases.41 Smoke-free laws that cover a broader range of venues, including all workplaces, restaurants, and bars, further reduce the risk of disease and death.42
  • Following implementation of Massachusetts’s statewide smoke-free law, heart attack deaths declined in cities and towns that previously did not have local smoke-free laws in place. There was no significant change in heart attack deaths in jurisdictions that previously had a local law, suggesting that the decline in heart attack deaths was due to the smoke-free law. 43
  • One year after New York State implemented a comprehensive smoke-free law, heart attack hospital admissions decreased by over 3,800, an 8 percent decline statewide.44
  • A 2011 ACS CAN report found that if all states that lacked comprehensive smoke-free laws passed one, more than a million adults would quit smoking and about 400,000 youth would never start, preventing 624,000 deaths.45 About 70,000 of these preventable deaths would occur in non-smokers.46

ACS CAN on Secondhand Smoke and Worker Health

Exposure to SHS is an occupational hazard for many U.S. workers, including casino, restaurant, bar, and hotel employees, and a preventable cause of disease and death. ACS CAN believes that all people should have the right to breathe smoke-free air. No one should have to choose between their livelihood and their health.

ACS CAN strongly supports legislative and regulatory measures that limit smoking in hospitality venues, work environments, and other public places. Furthermore, ACS CAN opposes preemptive state legislation that restricts local authorities from regulating smoke-free air and urges policymakers and community leaders to support smoke-free efforts, which reduce and prevent disease, suffering, and death from tobacco.
