Nicotine replacement therapy
NRT delivers nicotine to the smoker's brain in a much slower way than cigarettes do. It helps to damp down the urges to smoke that most smokers have in the early days and weeks after quitting, rather than remove them totally. It gives the smoker the chance to break smoking cues in their daily lives, and might provide a more comfortable exit from the smoking habit. NRT however is best used with some form of support, ideally from someone who knows something about smoking cessation.
