Experimental: Combination zonisamide and bupropion with e-cigarette
Participants enrolled in the study will receive a G6 e-cigarette at V2 for ad libitum use. After the first week of e-cigarette use, (at V3) participants will be given zonisamide and bupropion in addition to continued use of the G6. Use of these study drugs will continue for 12- weeks with a target complete switch date (from combustible cigarettes to e-cigarettes) one week after study drug initiation.

Drug: Zonisamide
Zonisamide (100 mg/daily) for 12 weeks.
Other Name: zonegran Drug: Bupropion Extended-release bupropion dosing (150 mg each morning days 1-3, then 300 mg/daily) for the remainder of the 12 weeks.
Other Names:
Other: Halo G6 e-cigarette G6 e-cigarette for ad libitum use for two weeks prior to complete switch day.
Other Name: e-cigarette |
- Number of Participants That Completely Switched From Combustible Cigarettes to Halo G6 E-Cigarettes [ Time Frame: Weeks 8-11 post-quit date (weeks 10-13 post baseline) ]Defined as self-report of no cigarette smoking (not even a puff), confirmed by an expired air CO reading of less than 5 ppm.
- Point Abstinence From Combustible Cigarettes [ Time Frame: Six months post switch day (approximately 6 months post baseline) ]Assessed by self-report utilizing an automated SMS messaging system.
- Change in Rewarding Effects of Smoking Combustible Cigarettes [ Time Frame: First week compared to after start of study drugs (Weeks 2-13 post baseline) ]Characterize changes in the two primary scales of the Cigarette Evaluation Questionnaire (mCEQ), assessing smoking satisfaction and psychological reward, compared between cigarettes smoked after meals versus all others smoked during the day, examining how this difference changes after zonisamide/bupropion usage. The mCEQ uses a 7-point scale (0=Not at all; 1=Very little; 2=A little; 3=Moderately; 4=A lot, 5=Quite a lot; 6=Extremely) to measure the following subscales: Satisfaction, Psychological Reward, Enjoyment of Respiratory Tract Sensations, Craving Reduction, Aversion.
