  3. Percentage of Participants With 7-day Point Prevalence of Smoking Cessation at Week 12 [ Time Frame: Week 12 ]
    Participants who abstained from smoking in last 7 days. Abstained = response of no to both Nicotine Use Inventory questions: "In last 7 days has subject 1) smoked any cigarettes (even a puff)?, and 2) used any other nicotine-containing products?".
