What does it mean when it mentions birth mother used cigarettes daily, marijuana weekly, etc.?

All our Birth mothers are required to fill out a self-report medical and social history. Included in the medical section are questions about substance use. We ask for information on the type of substances used, currently and in the past, and how often the substance was/is used. Of course, we cannot guarantee accuracy with any self-reported information, which is why we require substance testing. We maintain a judgment-free environment and encourage honesty from our Birth Mothers, but we also believe it is important to have as complete a history as we can get as it benefits everyone, especially the baby.
