Smoking itself is bad enough. It is even worse when a woman smokes while she is pregnant.

Some women do not mean any harm as smoking is a hard habit to break no matter how hard they try.

Nevertheless, smoking can cause serious health problems to unborn babies like heart murmurs, and so on.

Yes, some heart murmurs in young babies naturally close on their own, yet everyone is not always so lucky along with other problems such as chronic asthma and other respiratory problems that may result in life-threatening events.
