Blame nicotine, the addictive substance in cigarettes. Not only does nicotine cause powerful pleasurable sensations when it’s absorbed into the bloodstream, but it also triggers deep cravings after its effects wear off. The good news is that it’s possible to overcome nicotine cravings — with a little understanding, focus, and willpower, that is. Here’s how to kick the habit for good.

Why Stopping Smoking Makes You Feel So Bad

Nicotine is powerful stuff — and cigarettes deliver a quick supply of this drug to the brain, triggering a burst in the production of certain brain chemicals responsible for helping us feel pleasure, according to the National Institute on Drug Abuse (NIDA). Ten seconds after a smoker inhales, the nicotine level in his or her body peaks. But the problem is that the drug — and the pleasurable feelings it causes — also wears off quickly. In fact, most people who smoke do so to activate the rewarding sensation and avoid the negative consequences of depriving their bodies of nicotine. A typical smoker — for example, someone who takes 10 puffs on a cigarette over a 5-minute period and smokes about 30 cigarettes a day — gets about 300 nicotine hits to the brain every day, says the NIDA. When people stop consuming nicotine, they can experience physical withdrawal symptoms, like irritability and headaches, says Norman H. Edelman, MD, a professor of medicine at the State University of New York at Stony Brook and a senior scientific adviser to the American Lung Association. These symptoms usually creep up within hours of smoking your last cigarette and persist for approximately 15 to 20 minutes.

Know Your Smoking Triggers

Cigarettes aren’t just physiologically addictive — they’re also psychologically addictive. For most people, smoking is a habit that’s linked to certain daily activities and routines. Maybe you’re used to lighting up while you’re drinking your morning coffee or driving to work. These situations are known as trigger moments, and overcoming them can be difficult at first. Use these strategies to break your habits and stay smoke free for good.

Change your routine. If you’re in the habit of smoking after meals, leave the table as soon as you finish eating and take a short walk or engage in some other activity instead.Avoid your favorite bar. If you tend to smoke at a local bar or restaurant, going there can trigger the urge to light up, especially during the first few days of abstinence and nicotine withdrawal.Go to smoke-free areas. Spend as much time as possible in places where smoking isn’t allowed. Libraries, museums, theaters, and churches are just a few examples. Make your home and car smoke-free zones, too — and tell your family and friends about the new rule.

Reward Yourself for Not Smoking

Smoking is expensive. To encourage yourself to stay smoke free, set aside the money you’re saving by quitting for a treat — a vacation, a new guitar, or a bicycle. That’s something you can be proud of.
