Study Summary
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.
Primary Outcome
Prevalence of smoking ≥ 10 cigarettes/day in each group at final measurement by exhaled carbon monoxide level at last prenatal visit prior to delivery, as measured by exhaled carbon monoxide
Interventions
- DIAGNOSTIC_TEST knowledge of expired maternal carbon monoxide and fetal carboxyhemoglobin levels
