Cocaine is now regarded as one of the most dangerous illicit drugs ava
ilable today. A disturbing trend in the pattern of cocaine use is that
groups long considered unlikely to be involved in drug use, including
women of childbearing age, pregnant women, the pediatric age group, f
etuses, and neonates, are showing an alarming increase in cocaine expo
sure. Substantial data have been derived from clinical observations, c
linical studies, and animal studies indicating that prenatal exposure
to cocaine may have detrimental short-term and possibly long-term effe
cts on the mother, the developing fetus, and the neonate. The effects
attributed to cocaine may, however, be due to other substances (eg, al
cohol) ingested by the drug-using woman, to prematurity, or to the env
ironmental chaos in which the infant must develop. Prospective control
led studies are needed to define further the effects of cocaine as dis
tinct from other negative influences having an impact on the developin
g fetus. the newborn, or the infant.
