Primary outcomes (1)
Rate of Smoking Cessation
The primary outcome, smoking cessation, is defined as quitting smoking cigarettes completely by the end of the 12-week treatment period. This will be confirmed via exhaled carbon monoxide measurement. The rate of smoking cessation will be calculated as the proportion of participants who quit smoking over the 12-week treatment period.
Time frame: 12-weeks.
Secondary outcomes (3)
Reduction in smoking
Reduction in smoking will be defined as any decrease in the number of the cigarettes smoked a day from baseline to 12 weeks of treatment.
Time frame: 12 weeks.
Retention proportion
Retention is described as the proportion of enrolled participants who remain in the study until the end of the study period, having completed all assessments and carbon monoxide measurements.
Time frame: 24 weeks.
Treatment acceptability
The acceptability of the treatment, oral varenicline, from the participant's perspective will be measured using the Treatment Evaluation Inventory Short Form (score range 9-45, higher scores representing greater acceptance of a given treatment). Scores \> 27 will indicate at least moderate treatment acceptability.
