Dr. John Murphy:

Smoking is the issue that needs to be addressed by society because it affects the size of the baby. If the baby is smaller than it should be, it tends to get more distressed and may well deliver prematurely. There is a direct relationship in the case of smoking. Obviously, alcohol is completely not recommended in pregnancy. The number of cases of alcohol-related pregnancy problems that we encounter seems to be quite small. It is not a feature. Young women who are pregnant do not seem to do that. I have not noticed it to any great extent. I am sure Ms Wall agrees.
