Brief Summary
The purpose of this randomized controlled trial is to determine whether constituent disclosures on cigarette packs increase intentions to quit smoking. Previous studies have been informative, but they have evaluated candidate graphic warnings, not constituent disclosures. Furthermore, they typically expose participants to messages in controlled but artificial experimental settings for a short period of time, using much lower frequency and shorter duration of message exposure than found in the real world. This study addresses these issues by evaluating the impact of constituent disclosures by randomly assigning smokers to have their cigarette packs labeled with constituent disclosure messages or cigarette butt littering messages.

OTHERInterventions
Labels with constituent disclosure messages that include text about chemicals in cigarette smoke and health effects of the chemicals will be applied to participants' cigarette packs on the right side (the Surgeon General's warning is on the left side). At the week 2 visit, participants' packs will be labeled with 1 of 3 disclosures selected at random; at the week 3 visit, they will get one of the 2 remaining disclosures selected at random, and at the week 4 visit they will get the remaining disclosure. Study investigators developed the text and design of these labels.
Labels with litter messages that include text about littering cigarette butts will be applied to participants' cigarette packs on the right side (the Surgeon General's warning is on the left side). At the week 2 visit, participants' packs will be labeled with 1 of 3 litter messages selected at random; at the week 3 visit, they will get one of the 2 remaining litter message selected at random, and at the week 4 visit they will get the remaining litter message. Study investigators developed the text and design of these labels.
