Summary

This study planned to test newborn babies' hair for traces of drugs their mothers took during pregnancy. Hair can show drug exposure over months, unlike blood or urine tests. The goal was to better understand how these substances get into babies' hair. However, the study was withdrawn before any participants were enrolled.
