Smoking Blood supply to the fetus is limited causing low birth weight in infants and children that stay below normal weight; possible learning difficulties and mental deficiencies in the child.

Alcohol Consumption of alcohol in pregnancy has caused a high incidence of congenital deformities and mental retardation. Fetal alcohol syndrome: Infant is small for gestational age, mentally retarded, and has a characteristic craniofacial deformity.

Recreational Drug use Narcotics such as Demerol and Heroin have long been associated with causing harm to the developing fetus. Cocaine and crack are particularly harmful to the fetus because it causes vasoconstriction (blood vessels getting narrower – constricting). This slows the blood supply to the placenta (that nourishes the baby) or cuts off the nutrient supply. It can cause spontaneous abortion (miscarriage), pre-term labor, growth retardation, limb deformities (arms and legs), mental and emotional problems, learning disorders and attention deficit disorders.
