Quitting smoking is one of the most important things you can do for your health. The sooner you quit, the sooner your body can start to heal. You'll feel better and have more energy to be active with your family and friends.
Smoking hurts almost every part of the body.
Smoking tobacco is the leading cause of preventable death and disease in the United States.
For example, smoking cigarettes (which have tobacco in them) causes:
- Lung cancer, colorectal cancer, and many other types of cancer
- Heart disease and stroke
- COPD (chronic obstructive pulmonary disease)
- Pregnancy problems
- Gum disease
- Type 2 diabetes
- Vision loss
- Rheumatoid arthritis

Smoking hurts other people, too.
Secondhand smoke is a mix of the smoke that you breathe out and the smoke that comes from your cigarette. Secondhand smoke is dangerous and can cause health problems for the people around you.
In babies and children, breathing in secondhand smoke can cause:
- Sudden infant death syndrome (SIDS)
- Severe asthma attacks
- Ear infections
In adults, breathing in secondhand smoke can cause:
- Heart disease
- Lung cancer
E-cigarettes (sometimes called “vapes”) work by heating a liquid to make an aerosol that people breathe in. E-cigarette aerosol is not harmless. It can have harmful — and possibly harmful — substances, like heavy metals and chemicals that can cause cancer. Most e-cigarettes also have nicotine (the addictive drug found in tobacco products).
The U.S. Food and Drug Administration (FDA) has not approved e-cigarettes as a quit-smoking aid.

How Can I Quit?
You can quit smoking.
Quitting smoking is hard, but millions of people have done it successfully. In fact, more than half of Americans who ever smoked have quit. You could be one of them! It often takes people several tries to quit smoking, but don't get discouraged — every attempt to quit means you're one step closer to quitting for good.
Nicotine — the drug found in all tobacco products — is as addictive as heroin or cocaine. It’s the nicotine in cigarettes that causes cravings, or the strong feeling that you want to smoke. Remember — quitting isn’t easy, but it is possible!
Take these steps to help you quit:
- Make a list of the reasons you want to quit
- Set a quit date and make a plan to deal with cravings
- Ask your family, friends, and co-workers for support
- Talk to your doctor about counseling and medicines that can help you quit
- Call 1-800-QUIT-NOW (1-800-784-8669) or visit Smokefree.gov for free help
- Text QUITNOW to 333888 or visit SmokefreeTXT to enroll in a texting program for support with quitting

Make a quit plan.

- Take a different route to work
- Avoid activities and places you connect with smoking — at least for the first few weeks
- Spend time in places where smoking isn't allowed
- Make getting active and eating healthy part of your quit plan — eat healthy snacks, go for walks, and drink lots of water
Break the connection between eating and smoking.
Many people like to smoke when they finish a meal. Here are some ways to break the connection:

- Brush your teeth and think about the fresh, clean feeling in your mouth

Stress, Cravings, and Withdrawal
Deal with stress.
Some people smoke to deal with stress. But there are ways to deal with stress without smoking.
Manage stress by creating peaceful times in your daily schedule. Try relaxation methods like deep breathing, short walks, and meditation. Learn more about managing stress.
You can also check out these tips for dealing with stress as you quit.
Manage cravings and withdrawal.
When you quit smoking, your body and brain have to get used to not having nicotine. This can cause cravings — or urges — to smoke. You may also have symptoms of nicotine withdrawal. For example, you may:
- Feel irritable or restless
- Have trouble sleeping
- Be hungrier than usual
The good news is that, over time, cravings and withdrawal symptoms will fade as long as you do not smoke again.
Here are some ways to manage cravings and withdrawal:
- Keep your hands busy — try brushing your teeth, washing your hands, sorting the mail, or doing the dishes
- Have healthy snacks ready — like baby carrots, apples, or whole-grain crackers
- Distract yourself with a new activity — try playing a game on your phone, reading a book, or doing crosswords or other puzzles
- Get active — go for a walk, do some yard work, or try a workout class
- Take several deep breaths to help you relax
- Write down or read your list of reasons for quitting
- Connect with others — reach out to friends and loved ones who support your efforts to quit

Stick with It
Don’t give up!
It takes time to overcome addiction. Many people try to quit several times before they succeed. And it's normal to have setbacks — especially in the first 3 months after quitting.
If you slip up and have a cigarette, don't be hard on yourself — instead, get right back to trying to quit for good. Remember, quitting is one of the most important things you can do to protect your health.
Learn from the past.
If you’ve tried to quit before, think about what worked for you and what didn’t. For example, being around other people who smoke can make it harder to quit. So can drinking alcohol.
If you’re having a hard time staying smoke-free, talk with your doctor about what types of counseling or medicines might help you.
