There’s no right answer for everyone. In general, the available medications, whether nicotine replacement therapy, bupropion (Zyban) or varenicline (Chantix), all make it easier to quit and more likely that you’ll be successful. But at the end of the day, they are also a luxury – far more people quit worldwide without medications than do with them.
Quit-smoking medications work by reducing the severity of cravings and withdrawal symptoms, so your day to-day life feels more manageable. Research shows over and over again that when they’re used correctly, these medications can double or even triple your chances of successfully quitting smoking.
