Although studies indicate that public policy can influence the decrease in smoking behaviors, these policies have not necessarily transferred to home environments at the same rate. The authors surveyed 4,296 students in a southern urban area. African American students were 76.3% of the respondents and Caucasians accounted for 23.7%. African American homes are less likely to have full bans on smoking inside the home. Home smoking bans impact smoking behaviors, acceptance of smoking, susceptibility to smoking, smoking beliefs, and motivation to quit smoking. Along with home smoking bans, there are differences among African American and Caucasian youth in smoking exposure, behaviors, beliefs, and motivation to quit smoking. This study suggests that particularly in African American youth, educational efforts should be directed toward more restrictive home smoking policies to thwart the initiation of smoking in adolescents and to encourage positive attitudes toward smoking behaviors.
