We conducted a longitudinal study of a community-based cohort of HIV-infected indigent adults to examine smoking behaviors and factors associated with quitting. We assessed “hardcore-smoking behaviors associated with a low probability of quitting. Of the 296 participants, 218 were current smokers (73.6?%). The prevalence of “hardcore-smoking was high: 59.6?% smoked ?5 cigarettes per day, and 67.3?% were daily smokers. During the study interval, 20.6?% made at least one quit attempt. Of these, 53.3?% were abstinent at 6?months. The successful quit rate over 2?years was 4.6?%. Illegal substance use (adjusted odds ratio, AOR 0.2, 95?% CI 0.1-.6) and smoking within 30?min of waking (AOR 0.2, 95?% CI 0.1-.7) were associated with lower likelihood of making a quit attempt. Interventions that reduce nicotine dependence prior to smoking cessation and those that are integrated with substance use treatment may be effective for this population.
