Fetal growth, including head and brain size, may be impaired, strokes and seizures may occur, and malformations of the kidneys, genitals, intestines and spinal cord may develop.

The horrid litany is not just the result of binges. Even one "hit" of crack can irreparably damage a fetus or breast-fed baby...
Last year Pamela Rae Stewart learned that her pregnancy was complicated by a misaligned placenta. Dr. Paul Zlotnik advised her to avoid street drugs, abstain from sex and take prescribed medication.

...This pattern provides strong support for the theory that AIDS is spread by an infectious agent. But, says Dr. Richard O'Reilly, an immunologist at New York City's Memorial Sloan-Kettering Cancer Center, "whether it is transmitted by close association after birth or through the placenta, we do not know...
