Official title
Smoking Reduction In Gravid Women With Substance Use Disorders (SIGS): A Randomized Controlled Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of this study is to encourage smoking cessation in women with substance use disorders by providing knowledge of expired carbon monoxide. We hypothesize that women who are provided knowledge of their expired carbon monoxide and the associated percent fetal carboxyhemoglobin will have a greater success at quitting smoking during pregnancy than women who are not provided this information. A secondary aim of the study is to correlate expired carbon monoxide throughout pregnancy with infant birth weight.
