title: Alternate tobacco product and drug use among adolescents who use electronic cigarettes, cigarettes only, and never smokers.
abstract: OBJECTIVE
  To determine whether use of alternative tobacco products (i.e., cigars, blunts, hookah, smokeless tobacco), alcohol, and marijuana differs among adolescents who currently use (1) electronic cigarettes (e-cigarettes); (2) cigarettes only; and (3) never smokers.
  
  
  METHODS
  Analysis of a self-reported survey from four high schools in 2010-2011 (n = 3,102) with a subsample (n = 1,556) surveyed on alcohol and marijuana. Analyses were conducted with multinomial logistic regression models accounting for clustering by schools.
  
  
  RESULTS
  The sample contained 2.4% (n = 76) e-cigarette users, 12.4% (n = 386) cigarette smokers, and 85.1% (n = 3,197) never smokers. E-cigarette users were more likely than cigarette-only smokers to report blunt (adjusted odds ratio, 1.81; 95% confidence interval, 1.21-2.71) and hookah use (adjusted odds ratio, 3.12; 95% confidence interval, 1.90-5.13), but not cigar, smokeless tobacco, alcohol, or marijuana use.
  
  
  CONCLUSIONS
  E-cigarette users are more likely than cigarette smokers to use hookah and blunts.
