Tobacco smoking is a leading preventable cause of death and increases perioperative risk. Determinants of smoking abstinence after noncardiac surgery and the association between smoking and 1-yr vascular outcomes are not fully elucidated. ⋯ Long-term tobacco abstinence is more likely after major surgery in those with serious medical comorbidities. Interventions to prevent smoking resumption after surgery remain a priority. Clinical trial registration NCT00512109.
