Varenicline Standard Protocol
Participant chooses 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.
Varenicline Standard Protocol: 4 weeks pre-TQD: Start Placebo Varenicline 1 week prior to TQD: Switch to Active Varenicline
1 week prior to TQD: Start Placebo Bupropion Varenicline + Placebo Bupropion to 12 weeks post TQD

Nicotine Patch Standard Protocol
Participant chooses 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.
Nicotine Patch Standard Protocol: 4 weeks pre-TQD: Start Placebo Nicotine Patch TQD: Start active Nicotine Patch
1 week prior to TQD: Start Placebo Bupropion Nicotine Patch + Placebo Bupropion to 12 weeks post TQD

Varenicline Adaptive Protocol
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.
Varenicline Adaptive Protocol: VARENICLINE RESPONDER 4 weeks pre-TQD: Start Varenicline 2 weeks pre-TQD: DOES reduce cigs/day by \> 50% 1 week pre-TQD: Start Placebo Bupropion Varenicline + Placebo Bupropion to 12 weeks post TQD
VARENICLINE NON-RESPONDER 4 weeks pre-TQD: Start Varenicline 2 weeks pre-TQD: DOES NOT reduce cigs/day by \> 50%
1 week pre-TQD: Start active Bupropion Varenicline + Bupropion to 12 weeks post TQD

Nicotine Patch Adaptive Protocol
Participant chooses 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.
Nicotine Adaptive Protocol: NICOTINE PATCH RESPONDER 4 weeks pre-TQD: Start Patch 2 weeks pre-TQD: DOES reduce cigs/day by \> 50% 1 week pre-TQD: Start Placebo Bupropion Patch + Placebo Bupropion to 12 weeks post TQD
NICOTINE PATCH NON-RESPONDER 4 weeks pre-TQD: Start Patch 2 weeks pre-TQD: DOES NOT reduce cigs/day by \> 50%
1 week pre-TQD: Start Bupropion Patch + Bupropion to 12 weeks post TQD

Nicotine Patch Adaptive Protocol
n=28 Participants
Participant chooses 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.

SECONDARY outcome
Timeframe: 52 weeks post-TQDPopulation: Analysis of a clinical population with significant comorbidity and minimal exclusion criteria.
The percentage of participants who decreased the number of daily cigarettes smoked by 50% or more from the baseline assessment visit to 52 weeks post target quit day assessment visit collected by self-report in participants who completed the 52-week post target quit day phone assessment.
