OBJECTIVES: This study evaluated merchant compliance with laws prohibiting
the sale of tobacco to minors in Massachusetts. METHODS: Stratified cluster
sampling was used to select outlets from which youths aged 13 to 17 years
attempted to purchase tobacco. RESULTS: Illegal sales were more common when
the youth purchasing the tobacco was older, when the clerk was male, and
when tobacco was obtained from a self-service display or unlocked vending
machine. Failure to request proof of age was the strongest predictor of
illegal sales. CONCLUSIONS: Measured compliance rates are strongly
influenced by the age of the youths used to purchase tobacco.
