Study Summary

This study will test whether cigarette package inserts (i.e., small printed leaflets inside cigarette packs) with messages about the benefits of cessation and tips for quitting can help smokers quit. To do this, the investigators will conduct a 2 X 2 between-subject experiment in which 380 smokers will be randomized into one of four labeling groups: 1. no inserts or pictorial health warning labels (HWLs); 2. inserts only; 3. pictorial HWLs only; 4. inserts \& pictorial HWLs. Smokers will be given a 14-day supply of their preferred cigarette brand with packs labeled according to their experimental group. Participants will answer a brief survey at the end of each day and four other times each day, using ecological momentary assessment approaches. The investigators will study whether smokers in each group experience different psychological responses and behaviors associated with smoking cessation.

Primary Outcome

A single question measured on a continuous scale (1="Not at all", worse outcome; 7="Extremely", better outcome) to assess strength of confidence to quit smoking, with average scores (range 1-7) estimated.
