[The newborn infant of the drug-addicted mother. Experience relative to the period 1978-1986].

Ninety-seven newborns of drug addicted mothers observed in the period 1978-1986 were compared with the same number of controls. Pregnancies are at risk and newborns suffer a higher incidence of tainted amniotic liquid, low birth weight and preterm gestation. The withdrawal syndrome is the most commonly encountered pathology of such newborns.
