title: Openness to Using Non-cigarette Tobacco Products Among U.S. Young Adults.
abstract: BACKGROUND
  National data indicate that the prevalence of non-cigarette tobacco product use is highest among young adults; however, little is known about their openness to use these products in the future and associated risk factors. This study sought to characterize openness to using non-cigarette tobacco products and associated factors among U.S. young adults.
  
  
  METHODS
  In 2014, National Adult Tobacco Survey data (2012-2013) were analyzed to characterize openness to using the following tobacco products among all young adults aged 18-29 years (N=5,985): cigars; electronic cigarettes ("e-cigarettes"); hookah; pipe tobacco; chew, snuff, or dip; snus; and dissolvables. Among those who were not current users of each product, multivariable logistic regression was used to examine associations between demographics, cigarette smoking status, lifetime use of other non-cigarette products, perceived harm and addictiveness of smoking, and receipt of tobacco industry promotions and openness to using each product.
  
  
  RESULTS
  Among all young adults, openness to using non-cigarette tobacco products was greatest for hookah (28.2%); e-cigarettes (25.5%); and cigars (19.1%). In multivariable analyses, which included non-current users of each product, non-current ever, current, and former smokers were more likely than never smokers to be open to using most examined products, as were men and adults aged 18-24 years. Receipt of tobacco industry promotions was associated with openness to using e-cigarettes; chew, snuff, or dip; and snus.
  
  
  CONCLUSIONS
  There is substantial openness to trying non-cigarette tobacco products among U.S. young adults. Young adults are an important population to consider for interventions targeting non-cigarette tobacco product use.
