Abstract
Does tobacco use in polydrug users relate to future daily functioning (SF-36) and disability? To answer this question, community-living polydrug users (n = 254) were interviewed at baseline, 1-year and 2-year follow-up. Measures included: smoking status and self-reported disability at each assessment, and SF-36 measures collected at the final assessment. Urine samples permitted validation of reported drug use status. Results revealed that baseline disability rates were high but fell nearly 50% over two years. Disabilities named were similar to those reported in the general population. Change in smoking status was associated with decreased disability and improvements in general health and vitality. Respondents reporting disability reported lower daily functioning (SF-36). Stable everyday smoking was strongly associated with increased probability of positive urine tests for illicit drug use. Illicit drug use did not affect SF-36 ratings. Findings suggest that tobacco use by polydrug users is related to disability rates, to illicit drug use and to variations in daily functioning.
