Higher acculturation is associated with Asian American smoking prevalence decreasing in men and increasing in women. Asian immigrants in California are significantly more likely than their counterparts in Asia to have quit smoking. Smoke-free environments may mediate this acculturation effect because such environments are not widespread in Asia

In 2006, Asian American current and former smokers were analyzed using the 2003 California Health Interview Survey. For recent Asian immigrants and longer-term residents, having a smoke-free-home rule was associated with status as a former smoker. This association was stronger for recent immigrants. Having a smoke-free-home rule was associated with lighter smoking only for longer-term residents.

For Asian Americans, smoke-free-home rules are associated with status as a former smoker, particularly among recent immigrants, and lighter smoking in long-term residents. Interventions encouraging Asian Americans to adopt smoke-free-home rules should be evaluated.​
