Brief Summary
Medications for smoking cessation are currently only effective in helping a minority of smokers quit. Drug development is slow and expensive, so there is much interest in optimizing the effectiveness of existing treatments and medications. Current standard doses of nicotine replacement therapy (NRT) are not effective for many smokers and in many cases provide less nicotine compared to when a smoker is smoking their usual number of cigarettes. The proposed study will test if a personalized dose of nicotine patch (up to 84mg) will improve quitting success in those who do not respond to a standard dose of NRT (21mg).

Experimental Condition
EXPERIMENTALParticipants unable to quit smoking after 2 weeks of treatment with 21mg nicotine patch will get 21mg nicotine patches plus additional active nicotine patches until achieving 7 consecutive days of abstinence over the next 5 weeks; maximum daily patch dose, 84mg/day
Placebo Condition
PLACEBO COMPARATORParticipant unable to quit smoking after 2 weeks of treatment with 21mg nicotine patch will get 21mg nicotine patches plus placebo patches until 7 consecutive days of abstinence over the next 5 weeks; Maximum daily patch dose, 21mg active nicotine patch plus 3 placebo 21mg patches.
Quit condition
ACTIVE COMPARATORParticipants able to quit for 7 consecutive days during the first 2 weeks of treatment with 21mg nicotine patch will continue open label 21mg active nicotine patches for the remaining 10 weeks.
Interventions
