Thats why I offered up what is called an out, as we may notice in the post its says in my case, which aleviates any possible attacks on said post as being anecdotal or without scientific merit.
I smoked when pregnant, and all 4 of my children are higher than average in intelligence.
Maybe nicotine helps brain development.
Their fingers, toes, and other appendages are normal . And they were much healthier than their peers, in spite of all the second hand smoke they inhaled. And, get this, none of them are smokers today! Neither am I since New Year's.
I quit cold-turkey after 40 odd years of smoking, not because of health, but because of cost and social pressure. So far, doing fine.
