Biologically verified continuously smoking abstinence at week 26	26 weeks	Participants in this study will be considered to be biologically verified continuously smoking abstinence if they report smoking no more than 5 cigarettes since the quit date and have an expired carbon monoxide concentration of less than 10 ppm (for local participants who will be able to go to the PI affiliated hospital) or a urine cotinine cutoff point of 200 ng/ml (cotinine urine dipsticks will be mailed to each participant's address, and test will be confirmed by video call and by family members) at week 26 (6 months) after quit date. This abstinence has been applied by the Society for Research on Nicotine and Tobacco (SRNT) (Hughes, Keely et al. 2003) and the 'Russell Standard' (West, Hajek et al. 2005).
