Evaluation of Learning-Theory-Based Smoking Cessation Strategies

* Participants in this study are randomized to one of two treatments conditions prior to a target quit date. * One-half of participants will be randomly assigned to receive standard smoking cessation treatment comprising a 6-week supply of 21-mg nicotine patches and 4 individual smoking cessation counseling sessions. * The other one-half of participants will be randomly assigned to receive standard treatment (patch and counseling, as above) plus to practice quitting 7 times over the 2.5 weeks leading up to a quit attempt. Practice quitting will involve not smoking for a period of time tailored to each individual's smoking pattern. * All participants are asked to attend a 2-hour orientation session, complete 8 brief (5-minute) telephone calls and 9 longer(20-minute) telephone surveys over 3.5 weeks, attend a 30-minute office visit, and complete two 15-minute follow-up calls. * All participants are also asked to report on their emotions, thoughts, and behaviors 3 times per day for 24 days using cellular telephones. * Participants receive compensation for office visits, study telephone calls, cellular telephone reports, and follow-up interviews. * All participants will receive nicotine patches and one-on-one counseling (delivered over the phone and in person). * Some participants will be eligible for a second phase of treatment after a 4-week follow-up interview. * One-half of people eligible for this phase of the study will be randomly assigned to receive a supply of non-nicotine cigarettes to smoke for up to 6 weeks. The non-nicotine cigarettes are designed to help break the habit of smoking and to help smokers return to being smoke-free after smoking regular cigarettes. * The other one-half of eligible smokers will be randomly assigned to not receive these non-nicotine cigarettes. * All smokers eligible for this phase of the study will be asked to complete cellular telephone reports about their mood, thoughts, and behaviors for 14 days beginning 4.5 weeks after a target stop-smoking date. Compensation will be provided for completing these cellular telephone phone reports.
