Those substances also lead to:

Peptic ulcer irritation Low child birth weight Premature births Miscarriage Still births Neonatal deaths Cancer

20% of the unsuccessful pregnancies would have been successful had the mother not smoked

Child Birth Smoking Mother

Low birth weight Premature births Still births Neonatal deaths

Smoking Father (non-smoking mother-no second hand smoke) Greater increase in child birth problems (similar to but

lower than that of smoking mother)

Second hand smoke Greater increase in child birth problems
