To the Editor.

The findings that cocaine use during pregnancy was associated with growth retardation and microcephaly were consistent with earlier studies.2,3 On the other hand, the finding that cocaine use during pregnancy was not associated with increased occurrence of congenital anomalies was not consistent with recent studies.4,5
