Participants will be randomized to one of two conditions: (1) a Facebook-delivered intervention tailored to readiness to quit smoking; or (2) the control condition (referral to the Smokefree.gov website). The intervention will include 12 weeks of Facebook-based messages and activities tailored to participants' stage of change.
Assessments will occur at baseline, 3, 6, and 12 months follow-up. Assessments will include measures on smoking patterns and thoughts about abstinence. All participants who report no past 7-day smoking will be asked to give biochemical verification of smoking status with saliva cotinine test kits that will be mailed to participants.
