Study Arms:
- Varenicline Standard Protocol (Type: ACTIVE_COMPARATOR): Participant choses Varenicline-based treatment and is then randomized to Standard Treatment arm (N=75). Four weeks prior to target quit date (TQD), participant starts placebo Varenicline. Consistent with Varenicline Standard Treatment, 1 week prior to the TQD the participant will switch to active Varenicline and placebo Bupropion. Participant will continue active Varenicline and placebo Bupropion to 12 weeks post-TQD.
- Nicotine Patch Standard Protocol (Type: ACTIVE_COMPARATOR): Participant choses Nicotine patch-based treatment and is then randomized to Standard Treatment arm (N=75). Four weeks prior to target quit date (TQD), participant starts placebo Nicotine Patch. One week prior to TQD, participant will start placebo Bupropion. Consistent with Nicotine Patch Standard Treatment, participant will start active Nicotine Patch on TQD. Participant will continue active Nicotine Patch and placebo Bupropion to 12 weeks post-TQD.
- Varenicline Adaptive Protocol (Type: EXPERIMENTAL): Participant chooses Varenicline treatment and is randomized to Adaptive Treatment arm (N=75). Four weeks prior to target quit date (TQD), participant starts active Varenicline. Two weeks prior to TQD, cigarettes smoked per day is assessed. If the number of cigarettes smoked per day is reduced by \>50%, the participant is considered a Varenicline responder, and starts placebo Bupropion 1 week prior to the TQD. If the participant DOES NOT reduce cigarettes smoked per day by \>50%, the participant is considered a Varenicline non-responder and starts active Bupropion 1 week prior to TQD. Varenicline responders will continue active Varenicline and placebo Bupropion to 12 weeks post TQD. Varenicline non-responders will continue active Varenicline and active Bupropion to 12 weeks post TQD.
- Nicotine Patch Adaptive Protocol (Type: EXPERIMENTAL): Participant choses Nicotine treatment and is randomized to Adaptive Treatment arm (N=75). Four weeks prior to target quit date (TQD), participant starts active Nicotine Patches. Two weeks prior to TQD, cigarettes smoked per day is assessed. If cigarettes smoked per day is reduced by \>50%, the participant is considered a Nicotine Patch responder and starts placebo Bupropion 1 week prior to the TQD. If the participant DOES NOT reduce cigarettes smoked per day by \>50%, the participant is considered a Nicotine Patch non-responder and starts active Bupropion 1 week prior to the TQD. Nicotine Patch responders will continue active Nicotine Patches and placebo Bupropion to 12 weeks post TQD. Nicotine Patch non-responders will continue active Nicotine Patches and Bupropion to 12 weeks post TQD.
