1994 A Health Canada project found traces of cigarette smoke compounds in the fetal hair of non-smoking mothers. It was the first biochemical proof that even offspring of non-smoking mothers are affected by passive smoke

Wow! I didn't know that. I smoked and when I got pregnant with my first 3, I had to quit because it made me sick. I made my husband smoke outside. I always started up again and my kids were exposed anyway. When I got pregnant with Amy, I vowed to never put another cigarette in my mouth, and I haven't. To think that my first three were exposed and smelled like cigarette smoke until I quit appalls me.
