In a study of smokers who tried to quit smoking with the nicotine patch therapy, 39 were smoking one year after the treatment, and 32 were not smoking after the treatment ( based on data from 'High Dose Nicotine Patch Therapy., by Dale et al., Journal of the American Medical Association. Vol. 274, No. 17').
