Name Time Method Post-cessation smoking abstinence assessed by self-report and hair nicotine. Hair nicotine testing involves the collection of a sample of hair from the head, which is analysed in the laboratory to measure its nicotine content.[12 months post smoking cessation date.];Continuous smoking abstinence between quit date and end of study by self-report[Over the 12 month period after smoking cessation. During this period continuous smoking abstinence is measured by self-report on daily diary cards from Week 2 to Week 5, and for a fortnight every month thereafter. It is biochemically verified by exhaled carbon monoxide tests at each clinic visit (1, 3, 6, and 12 months post smoking cessation) and by the nicotine content of a sample of hair taken from the head at 12 months post-smoking cessation.]
