Nonsense !
Nicotine is the "toxin-of-the month".
Many healthy babies were born to mothers who smoked,drank alcohol,and chugged gallons of coffee while pregnant.
I'm one of them, and there are millions more like me.
Just look at an old episode of "I Love Lucy". Lucy and Ricky smoked like chimneys, even through her pregnancy, because Philip Morris was their sponsor (and they were heavy smokers in any case).
The kids (FReepers under 40) don't believe you.
