A method of weaning a smoker away from both nicotine and the oral fixation that accompanies a smoking habit by giving the smoker smaller and smaller doses of nicotine in the form of a patch or gum.

Nicotine replacement therapy supplies the body with small and controlled doses of nicotine, the addictive drug found in tobacco products. These nicotine doses help smokers quit by helping alleviating cravings and withdrawal symptoms. NRT medicines are available as both over the counter products (patches and gum), as well as prescription products (nasal sprays and inhalers).

Nicotine replacement therapy (NRT) is the use of various forms of nicotine delivery methods intended to replace nicotine obtained from smoking or other tobacco usage. These products are intended for use in smoking cessation efforts to help deal with withdrawal symptoms and cravings caused by the loss of nicotine from cigarettes. Several forms of NRT have been marketed, including the nicotine patch, inhaler, nasal spray, gum, sublingual tablet, and lozenge.
