title: Other tobacco product and electronic cigarette use among homeless cigarette smokers.
abstract: We determined the prevalence and correlates of other tobacco product and electronic cigarette (e-cigarette) use in a clinic-based sample of homeless cigarette smokers.
  
  
  
  In April-July 2014, we used time-location sampling to conduct a cross-sectional, in-person survey of 306 currently homeless adult cigarette smokers recruited from 5 clinical sites at Boston Health Care for the Homeless Program. We assessed past-month use of large cigars, little cigars, smokeless tobacco, and e-cigarettes. Among those who had used e-cigarettes, we assessed the reasons for doing so. We used logistic regression analysis to identify the participant characteristics associated with the use of each product.
  
  
  
  Eighty-six percent of eligible individuals participated in the survey. In the past month, 37% of respondents used large cigars, 44% used little cigars, 8% used smokeless tobacco, 24% used an e-cigarette, and 68% used any of these products. Reasons for e-cigarette use included curiosity (85%) and to help quit conventional cigarettes (69%). In multivariable regression analyses, homeless smokers with greater subsistence difficulties were more likely to use little cigars (p=0.01) and less likely to use e-cigarettes (p=0.001). Non-Hispanic black (p=0.01), Hispanic (p<0.001), and rough-sleeping (p=0.04) participants were more likely to use large cigars. Readiness to quit was not associated with other tobacco product use but was significantly associated with e-cigarette use to help quit smoking (p=0.02).
  
  
  
  Health care providers who serve homeless people should consider routine screening for the use of other tobacco products and e-cigarettes to help guide smoking cessation discussions and tobacco treatment planning.
