Does smoking increase my unborn babies risk of nicotine addiction?

Maternal smoking during pregnancy does not appear to increase the risk that the affected child will become a smoker, but if that child does become a smoker, there will be a greater chance that they will be addicted to nicotine. A study published in 2003 by Dr. Stephen L. Buka of the Harvard School of Public Health in Boston found that mothers who smoke a pack or more per day have children who are at double the risk of having tobacco addiction, compared to non-smoking mothers. Those who smoked less than a pack a day had children who had a 20% higher risk of tobacco addiction, compared to non-smoking mothers. This is another reason why it is important to avoid any smoking during pregnancy.

Like the smell of your neighbor's signature limburger cheese-and-clam stir fry wafting through walls and settling into the fabric of your living room couch, nicotine crosses the placenta and enters the bloodstream of the developing baby. Some studies show that babies born to smoking moms have an increased risk of nicotine addiction later in life.

But there are many other risks to your unborn baby if you smoke during pregnancy, including miscarriages, early or preterm birth, having a low-birth weight baby, and an increased risk of death in the first month of the baby's life. So quit smoking before you get pregnant, for both yourself and your unborn baby.

Worse than nicotine addiction, your baby will be small, more likely, than it would have been, have less brain function than it would have had, and have a whole mess of other problems because of hydrocarbons and nicotine after the first trimester.  Quit early for your baby's sake.  The hydrocarbons in cigarettes, and even the nicotine, affect your baby's brain development.
