If you were a heavy smoker (more than a pack per day) and found that you can't quit with just 1 form of NRT, you can use the 21mg patch with additional 2mg gum or lozenge for cravings. Combination therapy has helped many smokers quit who were unsuccessful on one NRT alone. You should speak with your physician if you have any questions about using combination therapy. If you were a light or casual smoker, you are less likely to benefit from additional NRT.
