The importance of the issue of secondhand smoking

The absence of a threshold for carcinogenesis in active smoking i. Duringthe number of youth and young adults who tried cigarette smoking during the past year increased from 1.

If those practices are adopted before a ban rather than following The importance of the issue of secondhand smoking, the apparent effect of the ban will be attenuated from the full effect and it can be difficult to assess how the ban itself changed exposure to secondhand smoke and to predict when a decrease in exposure might be expected to affect disease rates.

Overall, random misclassification of exposure in a particular environment or of an overall estimate would tend to bias estimates of risk from the true value toward the null. Among the possible reasons for that are increased awareness of health risks, wanting to be favorable role models, a desire for an odor-free environment, a change in social acceptability of smoking, or a desire to hide tobacco use IOM, The IARC monograph on involuntary smoking, published inconcluded that the evidence did not support a causal association between breast cancer and secondhand smoke IARC Do not allow anyone to smoke in your car, even with the window down.

In addition to advertising bans, WHO recommends health warnings on tobacco packages, cessation programs, and treatment of tobacco dependence in all member states WHO, The home is the primary source of secondhand smoke exposure for children, and multiunit housing residents are particularly vulnerable to involuntary exposure in their homes.

Declines in hospital admissions for acute myocardial infarction in New York state after implementation of a comprehensive smoking ban. This conclusion extends to all secondhand smoke exposure, regardless of location. One nested case-control study using urinary cotinine as a marker of secondhand smoke exposure found that cotinine levels were associated with the risk of lung cancer among nonsmoking women de Waard et al.

Active smoking may have effects on breast cancer development that tend to increase and decrease risk; tissues of smokers are exposed to carcinogens but smoking has antiestrogenic effects USDHHS Report of the advisory committee of the surgeon general of the public health service.

That could contribute to an underestimate of the actual effect had there been no prior ban. Do not smoke in the home or around the baby. Lung cancer and other disorders.

A substantial body of evidence on the association in adults between cigarette smoking and absence from work consistently demonstrates that smokers are significantly more likely to have greater workplace absenteeism HHS, Secondhand smoke contains more than 7, chemicals.

Secondhand smoke causes numerous health problems in infants and children, including more frequent and severe asthma attacks, respiratory infections, ear infections, and sudden infant death syndrome SIDS.

The study found that when the population was exposed about four times per month to antismoking advertising campaigns, smoking prevalence decreased by 0. In addition to having an increased risk of developing diabetes, evidence also indicates that, among patients with diabetes, cigarette smokers are more likely to suffer cardiovascular complications and to have higher mortality rates.

Other Cancer Sites Active smoking is firmly established as a causal factor The importance of the issue of secondhand smoking cancer for a large number of sites including lung, urinary tract, upper aerodigestive tract, liver, stomach, pancreas, and many others USDHHS ; Vineis et al.

Parties to the WHO framework convention on tobacco control. The evidence was judged sufficient inand there is even greater certainty now, reflecting the substantial new research published since that has reduced uncertainties related to mechanistic considerations and to methodologic issues in the epidemiologic studies.

For example, some locations had previously implemented partial bans, and some regions within the locations studied for example, New York City and several other large counties in the New York state study had previously implemented comprehensive bans Juster et al. Emerging Issues in Tobacco Use Major advances have been made in recent years to address the tobacco epidemic: Substantial data from cohort and case-control studies that directly address the hypothesis have now been published.

With the improved designs, therefore, bias becomes an unlikely explanation for the observed increase in risk. Emerging Issues in Tobacco Use Major advances have been made in recent years to address the tobacco epidemic: Current European efforts demonstrate successful smoking cessation as a result of comprehensive tobacco-control programs.

Preventing tobacco use and helping tobacco users quit can improve the health and quality of life for Americans of all ages. This report, published 20 years after the report, again concludes that involuntary smoking causes lung cancer in lifetime nonsmokers.

The comparable effects of secondhand smoke exposure from spouses and from the workplace on risk also argue against uncontrolled potential confounding as an explanation for the observed association, because the same set of confounders is unlikely to be operative for both exposure settings.

Public health researchers recognize the difficulties inherent in studying exposures such as secondhand smoke, where the RR associated with the exposure is anticipated to be small and the exposure is common.

Increased Susceptibility to Infectious Lung Diseases Due at least in part to its adverse impact on immune status, cigarette smoking predisposes the smoker to developing acute infectious respiratory illnesses such as pneumonia.

Raising the minimum age of sale for tobacco products to 21 years has emerged as a potential strategy for addressing use among this population. The RR estimates were 1. Wheezing and coughing are more common in children who breathe secondhand smoke.

Tobacco use is the largest preventable cause of death and disease in the United States. The health consequences of involuntary exposure to tobacco smoke: In cross-sectional studies of nonsmoking women, some investigators observed a higher risk profile for potential confounding factors such as a higher alcohol intake, a lower intake of vitamin supplements and dietary sources of various antioxidants, and a higher body mass index among women exposed to secondhand smoke compared with unexposed women Koo et al.

These reports concluded that the weight of epidemiologic evidence strongly suggests that active smoking is not causally related to breast cancer risk. A Report of the Surgeon General:Secondhand smoke (SHS) is also called environmental tobacco smoke (ETS). It’s a mixture of 2 forms of smoke that come from burning tobacco: Mainstream smoke: The smoke exhaled by a smoker.

Sidestream smoke: Smoke from the lighted end of a cigarette, pipe. Secondhand smoke is a serious health hazard causing more than 41, deaths per year. It can cause or make worse a wide range of damaging health effects in children and adults, including lung cancer, respiratory infections and asthma.

The American Lung Association has more information available on. These health effects can include difficulty getting pregnant, early menopause, osteoporosis, cervical cancer, and breast cancer. When coupled with birth control pills, smoking can also increase the risk for blood clots, stroke, and heart problems.

Secondhand smoke and laws about smoking in public places "What the smoker does to himself may be his business, but what the smoker does to the non-smoker is quite a different matter This we see as the most dangerous development to the viability of the tobacco industry that has yet occu.
