NRT, or Nicotine Replacement Therapy, is a method used to help individuals quit smoking by providing a controlled dose of nicotine without the harmful substances found in tobacco. It comes in various forms, including patches, gum, lozenges, inhalers, and nasal sprays. NRT aims to reduce withdrawal symptoms and cravings, making it easier for smokers to transition away from cigarettes. NRT is often recommended as part of a comprehensive smoking cessation program, which may also include counseling and support. Studies have shown that using NRT can significantly increase the chances of successfully quitting smoking compared to not using any aids.
