Nicotine repalement therapy (NRT)is not advisable. There are many studies that clearly show that this drug must not be part of our lifestyle at all. Although this drug is not causing cancer, it promotes cancer. Furthermore, its use during preganancy and lactation by the mother is inducing changes to the program that determines normal development and maturation of the offspring. These include, for example, interference with the development of the nervous system, kidney stucture changes, lung disease, premature aging of certain organs, to name a few. What it eventually boils down to is that many diseases that the offspring of mothers who smoke or use NRT experience later in life, was actually already induced during fetal and neonatal development.
