Design: Prospective telephone and internet interviews for six months. Participants: 535 new inhaler users. Main outcome: Structured interview about off-label use (that is, use of inhaler for non-cessation reasons or concurrent use of inhaler and cigarettes) and Diagnostic and statistical manual, fourth edition (DSM-IV) and International classification of diseases, 10th edition (ICD-10) criteria for abuse and dependence Results: Although many used inhaler and cigarettes concurrently at some time (43–55%), few used inhaler for non-cessation reasons (4–9%) and few persisted in off label use (8–16%; 95% confidence interval (CI) 5% to 19%). No participant met ICD-10 criteria for harmful use/abuse (95% CI 0% to 3.3%). Eight subjects (1.4%) appeared to meet DSM-IV or ICD-10 criteria for dependence on inhaler, but none were found dependent in a clinical expert interview (95% CI 0% to 3.3%). Conclusions: Although transient concurrent use of inhaler and cigarettes often occurs, use for non-cessation reasons, abuse and dependence are rare. ER -
