Nicotine replacement therapy (NRT) products such as nicotine gum, patches, lozenges, inhalers, and nasal sprays can help smokers quit by providing them with a controlled dose of nicotine which helps to reduce withdrawal symptoms and cravings. Inhalers deliver nicotine vapor directly to the lungs, similar to how a smoker would inhale cigarette smoke. Nicotine inhibitors, on the other hand, work by blocking the effects of nicotine in the brain, reducing the pleasurable effects of smoking and making it easier for smokers to quit. These medications include drugs like varenicline and bupropion. Ultimately, each individual may respond differently to these methods of quitting smoking, and it's important to consult with a healthcare provider to determine the best approach for quitting.
