Background
Most people who quit smoking relapse within a year of quitting. Little is known about what prompts renewed quitting after relapse or how often this results in abstinence.
Purpose
To identify rates, efficacy, and predictors of renewed quit attempts after relapse during a one-year follow-up.
Methods
Primary care patients in a comparative effectiveness trial of smoking cessation pharmacotherapies reported daily smoking every 6–12 weeks for 12 months to determine relapse, renewed quitting, and 12-month abstinence rates.
Results
Of 894 known relapsers, 291 (33%) renewed quitting for at least 24 hours and 99 (34%) of these were abstinent at follow-up. The average latency to renewed quitting was 106 days and longer latencies predicted greater success. Renewed quitting was more likely for older, male, less dependent smokers, and later abstinence was predicted by fewer depressive symptoms and longer past abstinence.
Conclusions
Renewed quitting is common and produces meaningful levels of cessation.
