Nicotine patches do not help women given up smoking during pregnancy, according to landmark research by the University of Nottingham.
Scientists from the university's UK Centre for Tobacco Control Studies have just completed the largest clinical study into whether standard-sized patches help pregnant women to quit.
A total of 1,050 woman, between the ages of 16 and 50 and between 12 to 24 weeks pregnant, were randomly chosen from seven antenatal clinics to take part in the study.
