In Alabama, a positive drug test can have dire repercussions for pregnant women and new mothers. Their newborns can be taken from them. They can lose custody of their other children. They can face lengthy sentences in the most notorious women's prison in the United States and thousands of dollars in fees and fines. Yet the hospitals that administer those drug tests — and turn the results over to authorities — are exceedingly reluctant to disclose their policies to the public. In many cases, they test mothers and babies without explicit consent and without warning about the potential consequences, ProPublica and AL.com have found.
