Data Up to Date as of:
On This Page:
In 2018 to 2019, 90.2% of adults aged 18 years and older reported a smokefree home environment.
Background
Many individuals and families, including both smokers and non-smokers, have voluntarily adopted smokefree rules for their homes, reflecting a change in community social norms. For children, smoking in the home is the main source of exposure to SHS. Studies have found that adoption of smokefree home rules is a significant predictor of smoking cessation success. To protect non-smokers living within public housing, the US Department of Housing and Urban Development has adopted a rule making all public housing smokefree. This rule was implemented in July 2018.
Secondhand smoke (SHS) is a mixture of the side stream smoke released by a smoldering cigarette, pipe, hookah or waterpipe, or cigar, and the mainstream smoke exhaled by a smoker. SHS is a complex mixture containing thousands of chemicals, including formaldehyde, cyanide, carbon monoxide, ammonia, and nicotine. More than 250 of the chemicals in SHS are known to be harmful, and at least 69 are known to cause cancer.
Conclusive scientific evidence documents that SHS causes premature death and disease in children and adults who do not smoke. Among adults, exposure to SHS has immediate adverse effects on the cardiovascular system, and long-term exposure to SHS causes coronary heart disease and lung cancer. Children exposed to SHS are at increased risk for sudden infant death syndrome, acute respiratory infections, middle ear disease, more severe asthma, respiratory symptoms, and slowed lung growth.
There is no risk-free level of exposure to SHS, and only eliminating smoking in indoor spaces fully protects nonsmokers from exposure to SHS. Due to shared ventilation ducts and other related airborne conduits, SHS exposure may occur within multi-unit housing by smoke drifting to the homes of non-smokers.
Measure
The percentage of respondents reporting a smokefree home.
Healthy People 2030 Target
- Increase the proportion of smokefree homes to 92.9 percent.
Healthy People 2030 is a set of goals set forth by the Department of Health and Human Services.
