The only question I have is, how does smoke effect an unborn childs lungs, when the lungs aren't breathing air until it's born?
Oxygen is transferred to the blood stream directly from the mother to the fetus. Smoke would not have any effect on the development of the lungs.
I had trouble with that one myself. I don't have any explanation other than the mother's inhalation being taken in through the lungs to filtrate somehow from their to the fetus' circulatory system, which they share until the umbilicus is severed.
Smoke would not have any effect on the development of the lungs.

WRONG. Perhaps reading the article again 3-4 more times might help.
FYI, smoke has 100's of carcinogens. SIMPLE FACT.
FYI, smoke born chemicals entering the mother get into her blood stream. SIMPLE FACT
FYI, said chemicals effect the very sensitive developing lung cells and the whole processes involved with said lung cells. SIMPLE FACT.
The assertion quoted from the ref'd post is SIMPLY WRONG.
HARD SCIENTIFIC FACTS HAVE REPEATEDLY PROVEN SUCH A NOTION ABUNDANTLY WRONG.
as in W R O N G, WRONG.
I suspect that similar damage would be observed in other types of cells. Direct inhalation contact is not implied.
