Facilitating Smoking Cessation With Reduced Nicotine Cigarettes
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.

Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Experimental: Study 1: Immediate Reduction
Participants 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.
|
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.
Other Names:
All participants will receive One on One Counseling.

Experimental: Study 1: Gradual Reduction
Participants 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.
