The best source for information on illicit drug use in pregnant and lactating women is the National Association for Perinatal Addiction Research and Education (NAPARE). Their office is 200 N. Michigan Ave, Suite 300, Chicago IL 60601. They have some wonderful information, including very good policies on breastfeeding. I think the phone number is 312-541-1272, but call Information to be sure. Linda Smith, Dayton OH
