Nicotine replacement works by helping to give your body a steady dose or alternative source of nicotine that you can gradually wean yourself off of. They are also a safer alternative to cigarettes. It's best to combine a patch, which is long acting, with a more short acting agent like gum, lozenges, the puffer, or the nicotine nasal spray. The patch gives you a steady dose in your blood stream over 24 hours to help prevent withdrawal. The shorter acting nicotine replacement helps during times of intense craving.
