Well....Nicorette is what is known as replacement therapy. The goal is to add Nicotine to your body through the gum to slowly ween you off of nicotine and/or smoking. So, yes, you are still adding nicotine to your body which is not good. But the hope is that over time you will be able to stop the need for nicotine.
Of course it isn't great, but it is better than cold turkey, which can be nearly impossible due to the veracity of nicotine addiction.
