Eksperimentel: Scheduled Gradual Reduction + Varenicline
Participants will be given the behavioral intervention of Scheduled Gradual Reduction along with the smoking cessation drug, Varenicline.
|
Participants will receive a four-week Scheduled Gradual Reduction (SGR) intervention in which participants cut down on the number of cigarettes smoked.
This is done through a smoking schedule in which participants smoke a cigarette at given fixed and equal intervals throughout their waking day.
Additionally, they will take 0.5 mg of Varenicline (VN) once a day for the first three days, then 0.5 mg twice a day for the next four days, and they will continue for 13 weeks at 1.0 mg twice per day.
