Income associations with cigarette purchasing behaviors and quit attempts among people experiencing homelessness

Cigarette purchasing behavior may reflect quitting intentions. Little is known about how income could modify the association between cigarette purchasing behaviors and quit attempts among smokers experiencing homelessness.

Homeless, current smokers completed a questionnaire on the amount spent weekly on cigarettes (≤$20/week versus >$20/week), source of cigarettes (store versus other source), quantity of cigarettes purchased (

Of the 472 currently smoking individuals, 55% reported spending >$20/week on cigarettes, 83% reported purchasing cigarettes from a store, and 86% reported purchasing ≥pack during their last purchase. Those who reported an income spent a third of their monthly income on cigarettes, and were more likely to spend >$20/week on cigarettes. The amount spent weekly on cigarettes and the source of cigarettes was not associated with quit attempts, nor did income moderate these relationships. Persons without an income who bought a pack or more of cigarettes made fewer quit attempts (β = -0.4, 95% CI -0.7, -0.2), whereas the association between quantity of cigarettes purchased and quit attempts was not significant for those with an income (β = -0.2, 95% CI -0.4, 0.1).

Current smokers experiencing homelessness and who are without an income may find it particularly challenging to engage in attempts to quit smoking. Smoking cessation interventions that highlight relief of financial hardship as a potential benefit of successfully quitting smoking may be useful among this population.
