Nicotine Replacement Therapy
Nicotine replacement therapy (commonly abbreviated to NRT) is the remedial administration of nicotine to the body by means other than tobacco, usually as part of smoking cessation.
Common forms of nicotine replacement therapy are nicotine patches (which transdermally administers nicotine) and nicotine gum (which orally administers nicotine). The primary benefit of nicotine replacement therapy is that it prevents cravings in a smoker whilst allowing him to abstain from tobacco—and thus avoid the harmful effects of smoking.
