Nicotine Delivery Systems are methods used to provide nicotine to users, primarily to help manage cravings and withdrawal symptoms associated with tobacco cessation. These systems include traditional products like cigarettes, as well as alternatives such as vaping devices, nicotine patches, and gum. Each system delivers nicotine at different rates and intensities. The effectiveness of these systems varies based on individual preferences and health considerations. For instance, vaping can deliver nicotine more quickly than patches, while gum allows for more control over intake. Understanding these options can help users choose the best method for their needs.
