This act amends Tennessee’s fetal homicide law to allow the prosecution of a pregnant woman for the illegal use of a narcotic drug, if her child is born addicted or harmed by the drugs she took during her pregnancy. The charge of assault is a misdemeanor offense, but if the child is harmed, aggravated assault, with a 15-year maximum prison term, could be charged. That a woman is enrolled in long term drug addiction treatment before the child is born, remains in the program after delivery and successfully completes the program is an affirmative defense under the law. The law is set to expire on July 1, 2016.
