Related to Pregnancy. Marijuana May Harm Fetus. March 25, 2003 -- Smoking marijuana during pregnancy may cause lasting behavioral and mental defects in the child. A new study in animals suggests that children who are exposed to marijuana in the womb may suffer from a variety of long-term problems even if they aren't born with obvious birth defects.
Studies of marijuana in pregnancy are inconclusive, because many women who smoke marijuana also use tobacco and alcohol. Smoking marijuana increases the levels of carbon monoxide and carbon dioxide in the blood, which reduces the oxygen supply to the baby. Smoking marijuana during pregnancy can increase the chance of miscarriage, low birth weight, premature births, developmental delays, and behavioral and learning problems.
