Little Cigars and Cigarillos Use Among Young Adult Cigarette Smokers in the United States: Understanding Risk of Concomitant Use Subtypes

摘要

Introduction:In 2016, the Food and Drug Administration announced that it would regulate little cigars and cigarillos (LCCs) and expressed concern about the concomitant use of combustible tobacco products. To understand LCC use among socially-disadvantaged cigarette smokers, we assessed (1) the prevalence of concomitant use of subtypes of LCCs: LCC-tobacco, LCC-blunt, and LCC- poly use, which includes use of both LCC-tobacco and LCC-blunt and (2) and its association with sociodemographic factors and substance use behaviors using race/ethnicity and gender stratified models.
