Smoking outcomes
The primary outcome related to smoking will be 7-day point prevalence abstinence (i.e., no smoking at all in the past 7 days, not even a puff), which will first be assessed by self-report. If participants self-report ≥ 7-day abstinence, we will bio-verify their self-report. Saliva cotinine will be the primary bio-verification method (saliva cotinine of less than < 10 ng/ml will be considered abstinent)
