The study found that about 20 percent of adults in multiunit housing used combustible tobacco products

Americans living in multiunit housing, such as apartments and condominiums, are more likely to use tobacco products and less likely to have smoke-free home rules than people living in single-family housing, according to a new study conducted by the Centers for Disease Control and Prevention (CDC).

Published in the American Journal of Preventive Medicine, the CDC says that this is the first national study to document these tobacco use and exposure comparisons.

Using data from the 2013-2014 National Adult Tobacco Survey, CDC researchers found that 25 percent of adults age 18 and older who lived in multiunit housing used a tobacco product, compared with 19 percent of adults living in single-family homes. Additionally, the study found that about 20 percent of adults in multiunit housing used combustible tobacco products, which are a source of secondhand smoke exposure. Combustible tobacco product use among single family home adults was about 14 percent.

CDC researchers also found that about 34 percent of multiunit housing residents who have adopted voluntary smoke-free home rules have recently been exposed to secondhand smoke that entered their living unit from nearby living units or shared areas.

"These findings show the importance of protecting all people who live in multiunit housing through smoke-free building policies and access to tobacco cessation resources," said Corinne Graffunder, Dr.P.H., director of the CDC's Office on Smoking and Health. "Smoke-free rules help reduce secondhand smoke exposure among nonsmokers, prevent smoking initiation among youth and adults, support tobacco cessation among current smokers, and reduce the social acceptability of smoking."

The study also found disparities in tobacco use across population groups. Use of any tobacco product in multiunit housing was highest in their respective demographic categories among men; adults ages 45-64; non-Hispanic blacks; unmarried adults; lesbian, gay, and bisexual adults; people living in the Midwest; people with a high school diploma but no college education; and people with annual household income less than $20,000.

The study found that 81 percent of multiunit housing units had smoke-free home rules, compared with 87 percent of single-family homes. Among multiunit housing residents with smoke-free home rules, 34 percent reported that secondhand smoke involuntarily entered their homes from somewhere else in or around the building. Almost 8 percent reported secondhand smoke entered their homes every day, and 9 percent reported secondhand smoke entered a few times a week.

"The Surgeon General has concluded there is no safe level of exposure to secondhand smoke. Opening windows or using ventilation systems does not effectively eliminate secondhand smoke exposure in multiunit housing," said Brian King, Ph.D., deputy director of research translation in the CDC's Office on Smoking and Health and a co-author of the study. "Exposure to secondhand smoke from cigarettes causes more than 41,000 deaths among nonsmoking adults each year, and about $5.6 billion annually in lost productivity caused by premature death."

According to the CDC, the U.S. Department of Housing and Urban Development (HUD) has encouraged public housing authorities to implement smoke-free policies on their properties since 2009. In 2010, HUD issued similar guidance to owners and managers of multi-family housing rental assistance programs, such as Section 8. On November 12, 2015, HUD proposed a policy for U.S. public housing that, if implemented as proposed, would prohibit the use of "lit" tobacco products (cigarettes, cigars, or pipes) in all living units, indoor common areas, administrative offices, and all outdoor areas within 25 feet of housing and administrative office buildings. As of October 2015, several hundred public housing authorities across the U.S. had already instituted such policies.

Additionally, 22 communities in California have enacted laws that prohibit smoking in all multiunit housing, including living units, in both government-subsidized and privately owned multiunit housing. The CDC says that a growing number of owners and managers of multiunit housing have also voluntarily implemented smoke-free policies on their properties.
