PEORIA, Ill. -- New research is showing that pregnant women might have more trouble kicking their smoking habit if they use nicotine patches.

The French study of 400 pregnant smokers found nicotine patches did not improve quit rates any better than a placebo.

Women who used nicotine patches also had significantly higher blood pressure than those in the placebo group.

Women smoking during pregnancy are strongly encouraged to quit because of possible risks to both mother and baby.
