Brief summary

The goal of this study is to understand how information about smokers' health risks affects their attitudes, mood, and behavior.

Detailed description

The current study will test a community-based, tobacco intervention. The project will compare the effects of a proactive, personally-tailored, biologically-based motivational intervention to those of a proactive, generic motivational intervention for smoking cessation. The biologically-based motivational treatment will include feedback on participants' carbon monoxide (CO) exposure (expired CO and estimated carboxyhemoglobin levels), pulmonary functioning assessed via spirometry, and self-reported smoking-related symptoms. All participants will be given equal access to action-oriented treatment.
