Project 4, Study 2: Extended Exposure to Low Nicotine Content Cigarettes in Pregnant Women

Overview

Study 2 will evaluate the effects of extended exposure to cigarettes with varying levels of nicotine in pregnant smokers who have less than an Associate's degree. This study will be limited to two conditions: usual brand vs. 0.4 mg nicotine/g tobacco. After a baseline period in which daily smoking rate and other baseline assessments are completed, participants will be randomly (by chance) assigned to either their usual brand or the very low nicotine content condition and followed for 12 weeks.

Some inclusion/exclusion criteria are purposely omitted at this time to preserve scientific integrity. They will be included after the trial is complete.
