Brief Summary
STUDY 1: INTERVENTION DEVELOPMENT The purpose of this study is to determine the best way to help people stop smoking by using very low nicotine content (VLNC) cigarettes. This developmental pilot study (n=20) will determine the feasibility of the treatment approach and methodology using a targeted intervention, and lead to refinements for a subsequent randomized controlled trial (RCT). STUDY 2: RANDOMIZED CONTROLLED TRIAL The purpose of this study is to see if a targeted intervention will help people to stop or reduce smoking better than a standard intervention using very low nicotine content (VLNC) cigarettes, and to determine the optimal nicotine tapering schedule (gradual vs. immediate) during a 5-week pre-quit period. About 208 participants will take part in this phase of the study at Moffitt Cancer Center.

Outcome Measures
Primary Outcomes (3)
Study 1 - Rate of Participant Completion of Pilot
Pilot: Complete formative research based on 15 participants to prepare for Study 2.
Up to 2 Weeks
Study 2 - Participant Abstinence Success at 2 Months
Participants reporting 7-day point prevalence abstinence at 2 months RCT: The purpose of Study 2 is to test effects of the targeted intervention developed in Study 1 on smoking cessation. Comparison of abstinence success per treatment arm, utilizing 7-day point prevalence abstinence at each follow-up assessment.
At 2 Months
Study 2 - Participant Abstinence Success at 6 Months
Participants reporting 7-day point prevalence abstinence at 6 months RCT: The purpose of Study 2 is to test effects of the targeted intervention developed in Study 1 on smoking cessation. Comparison of abstinence success per treatment arm, utilizing 7-day point prevalence abstinence at each follow-up assessment.
At 6 Months
Study Arms (6)
Study 1: Immediate Reduction
EXPERIMENTALParticipants will receive cigarettes with the lowest nicotine dose (.03 mb nicotine yield). They will receive a targeted intervention workbook ("Count down: Preparing to Quit Smoking with Low-Nicotine Cigarettes") and will be provided with one-on-one counseling.
Study 1: Gradual Reduction
EXPERIMENTALParticipants will receive VLNC (very low nicotine cigarettes) containing nicotine yields of .7 mg for week 1, .26 mg for week 2, .12 for week 3, and .03 for week 4.They will receive a targeted intervention workbook ("Count down: Preparing to Quit Smoking with Low-Nicotine Cigarettes") and will be provided with one-on-one counseling.
Study 2: Targeted/Immediate Reduction
EXPERIMENTALParticipants will receive VLNC (very low nicotine cigarettes) containing nicotine yields of .7 mg for week 1, .26 mg for week 2, .12 for week 3, and .03 for week 4.They will receive a targeted intervention workbook ("Count down: Preparing to Quit Smoking with Low-Nicotine Cigarettes") and will be provided with one-on-one counseling.
Study 2: Targeted/Gradual Reduction
EXPERIMENTALParticipants will receive VLNC (very low nicotine cigarettes) containing nicotine yields of .7 mg for week 1, .26 mg for week 2, .12 for week 3, and .03 for week 4. Participants will also receive targeted materials (booklet series entitled ("Count down: Preparing to Quit Smoking with low-Nicotine Cigarettes") as well as one-on-one counseling.
Study 2: Generic/Immediate Reduction
EXPERIMENTALParticipants will receive VLNC (very low nicotine cigarettes) with the lowest nicotine dose (.03 mb nicotine yield). Participants will also receive the generic ("Clearing the Air") materials, as well as one-on-one counseling.
Study 2: Generic/Gradual Reduction
EXPERIMENTALParticipants will receive VLNC (very low nicotine cigarettes) containing nicotine yields of .7 mg for week 1, .26 mg for week 2, .12 for week 3, and .03 for week 4. Participants will also receive the generic ("Clearing the Air") materials, as well as one-on-one counseling.
Interventions
Eligible participants will receive a 1-week supply (based on typical # cigarettes/day x 1.5) of normal nicotine content (NNC) (.8 mg nicotine yield) study cigarettes to smoke exclusively during one baseline week. Study 1: Participants (n=20) will then be randomly selected to receive either the lowest nicotine dose of VLNC cigarettes, or gradual decreasing nicotine VLNC cigarettes, ten participants per each group, over the next four weeks. Study 2: Participants (n=208) will be randomly assigned to 1 of 4 Study 2 Reduction Arms, 52 participants per arm.
All participants will receive One on One Counseling.
