Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
