 - Pregnancy. Women who report being pregnant at the time of randomization will be excluded from participation. This latter exclusion criterion is based on the following reasons: a The interaction of drug use in any amount and fetal-maternal health is physiologically complex and beyond the scope of this proposed intervention. b Drug users who are pregnant are considered high-risk pregnancies and will likely be lost to follow-up during the study as they will be promptly referred by their primary care clinician to an obstetrician per usual clinic protocol. However, enrolled patients who become pregnant after the intervention will not be withdrawn. Their eventual exits from the study will be counted as drop-outs and will be included as no change in our intent to treat analysis. Finally, c a tailored brief intervention protocol for pregnant women may require more than simple clinician advice and a 2-session phone health education program. Such an intervention would be more effective if designed around the activities of prenatal care. Previous RCTs of problem alcohol use targeting healthy adults have excluded patients who are pregnant.8,9
