This document discusses nicotine replacement therapies (NRTs) for smoking cessation. It summarizes studies that have shown mixed results on the effectiveness of NRTs like patches and gum in helping smokers quit permanently. A recent large study found that NRTs did not prevent smokers from returning to cigarettes. The document suggests that willpower and addressing the psychological aspects of addiction may be more important than NRTs for quitting smoking successfully. It concludes that both NRTs and cold turkey methods can work, depending on the individual, and the goal is to provide hope to those trying to quit smoking.
