We know that smaller weight babies have more difficulty in thriving in an early life, so that it takes both babies who are light in weight at the time of birth, will take at least a year of good care before they will come up to the standards.

So what are the results, does money talk in this case, or are women in your practice buying the idea? Well, money partially talks.

We have had 75 women who have completed their pregnancy who have previously smoked. And of those 75 women, 35 of them have gone without smoking during the pregnancy. So they're getting the 100 dollars, they are getting 100 dollars back. Certainly we haven't had any low birth weight children in that group of patients.

How do you know for sure that those 35 women have indeed not smoked at all? May be they're misleading you. It's all an honor system. Each time they come for an examination they reaffirm their refusal to smoke. And certainly we trust those patients and feel they are following it. Other patients, of course, have stated they have started smoking again. So I think it's a pretty good cross section.

And just one more thing, and when, if we come back to you in a year from now, how much do you think...I can improve those figures.

Let me ask you this though, how much do you think you will be paying women to stop smoking? Well, we'll probably be raising it up to 200 or 250 dollar range, I would think. Ervin Mann is an obstetrician at Paxtang, Pennsylvania.
