  • About 80 million (1 in 4) people in the US live in multiunit housing, such as apartments, including about 7 million living in government-subsidized housing.3,4

What is government-subsidized housing?
When the government helps people pay their rent. Public housing is one type of subsidized housing.

Each year, an estimated 28 million multiunit housing residents are exposed to secondhand smoke in their home or apartment that came from somewhere else in their building like a nearby apartment.3,5

Every person living in multiunit housing deserves to breathe smokefree air.

Approximately 1 in 3 multiunit housing residents are covered by smokefree building policies.5

About 8 in 10 multiunit housing residents have chosen to make their own homes smokefree.5

A majority of multiunit housing residents want smoke-free building policies.5

Did You Know banner

Secondhand smoke can travel into an apartment from other apartments and common areas through doorways, cracks
in walls, electrical lines, ventilation systems and plumbing.1,

Opening windows and using fans does not completely remove secondhand smoke.1,

Heating, air conditioning and ventilation systems cannot eliminate exposure to secondhand smoke. In fact, these systems can distribute secondhand smoke throughout a building.1,

What is secondhand smoke?
It is the combination of smoke from the burning end of a cigarette and the smoke breathed out by a smoker.

When a person smokes near you, you can be exposed to secondhand smoke.

The Surgeon General concluded banner

There is no safe level of secondhand smoke exposure.1

Cleaning the air and ventilating buildings cannot get rid of
secondhand smoke.1

Secondhand smoke causes disease and early death in children and in adults who do not smoke.1

In the United States banner

Approximately 58 million (1 in 4) nonsmokers are exposed to secondhand smoke.6

About 2 in 5 children (including 7 in 10 black children) are exposed to secondhand smoke.2

The home is the main place where children are exposed to secondhand smoke.1,2

Secondhand smoke exposure among babies and children can cause1,7:

  • Sudden Infant Death Syndrome (SIDS)
  • Lung problems
  • Ear infections
  • Asthma attacks

Secondhand smoke exposure among adults can cause1,7:

  • Heart disease
  • Stroke
  • Lung Cancer

  • Improve Air Quality
  • Improve Health
  • Reduce Secondhand Smoke Exposure
  • Receive Public Support
  • Reduce Smoking in Youth,Young Adults, and Adults

Smokefree policies in multiunit housing can improve health and save money.

If all public housing in the United States was made smokefree, it would save $153 million each year, including

$43 million in costs from cleaning apartments where people have smoked

and $16 million in costs from fires caused by smoking.8

Savings would be even greater if all multiunit housing across the country went smokefree.
