We use a pooled time-series cross-section of live births in New York City between 1980 and 1989 to investigate the dramatic rise in low birthweight, especially among Blacks, that occurred in the mid 1980s. After controlling for other risk factors, we estimate that the number of excess low birthweight births attributable to illicit substance abuse over this period ranged from approximately 1,900 to 3,800 resulting in excess neonatal admission costs of between $22 and $53 million. We conclude that illicit substance use was a major contributory factor in rapid rise of low birthweight among Blacks in New York City in the latter part of the 1980s. The impact of prenatal illicit substance use on Whites and Hispanics is less conclusive.
