Abstract
Determine associations of strength of local smoke-free laws and urban/rural location with cigarette and smokeless tobacco use among high school students in grades 10 and 12. Secondary data analysis from the 2004-2018 biennial Kentucky Incentives for Prevention Survey. Public high schools in Kentucky. N = 353502 10th/12th graders. County-level smoke-free law status from the Kentucky Center for Smoke-free Policy; Rural Urban Continuum Codes; self-reported last 30-day alcohol, marijuana, cigarette, and smokeless tobacco use. Generalized estimating equations modeling assessed the association of law status and urban/rural location with tobacco use across cohorts, controlling for demographics and other substance use. Students in counties with a comprehensive smoke-free law were 23% less likely to smoke cigarettes and 16% less likely to use smokeless, compared to those in counties without a law. Students in counties with moderate/weak laws did not differ in likelihood of use for either product, compared to those in counties without a law. Students in urban counties were 14% less likely to smoke, but there was no difference in likelihood of smokeless use by urban/rural location. Comprehensive smoke-free laws are associated with a lower likelihood of youth cigarette and smokeless use. Rural youth may be at increased risk of cigarette smoking relative to youth in urban areas.
