Secondhand Smoke

Smoking hurts other people, too.

In babies and children, breathing in secondhand smoke can cause:

  • Sudden infant death syndrome (SIDS)
  • Pneumonia
  • Bronchitis
  • Severe asthma attacks
  • Ear infections

In adults, breathing in secondhand smoke can cause:

  • Heart disease
  • Stroke
  • Lung cancer

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!

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 Action

Make a Plan

Take these steps to quit smoking.

Write down your reasons to quit.

Make a list of all the reasons you want to quit. For example, maybe you want to set a healthy example for your children and save money. Keep the list with you to remind yourself why quitting is worth it.

Set a quit date.

  • Pick a date that gives you enough time to get ready to quit — but make sure it’s soon enough that you don’t lose your motivation
  • Tell your family, friends, and coworkers about your quit date so they can support you

Make a quit plan.

  • Think about situations that might trigger you to smoke and plan how you’ll handle them without smoking
  • Right before your quit date, go through your house, car, and workplace to get rid of anything that has to do with smoking — throw away all your cigarettes, ashtrays, lighters, and matches
  • Clean your clothes so they don’t smell like smoke

Change Routines

Switch up your daily routine.

Changing your routine on your quit date and afterward can help you break habits related to smoking. Try:

  • Taking a different route to work
  • Avoiding activities and places you connect with smoking — at least for the first few weeks
  • Doing things and going places where smoking isn’t allowed
  • Making 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:

  • Get up from the table as soon as you're done eating
  • Brush your teeth and think about the fresh, clean feeling in your mouth
  • Go for a walk after meals

Stress and Cravings

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

Manage cravings.

When you quit smoking, the urge to smoke will come and go, but it'll gradually decrease over time. Most cravings only last a short time. 

Here are some ways to manage cravings:

  • 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
  • Try chewing sugar-free gum to keep your mouth busy 
  • Distract yourself with a new activity — try playing a game on your phone, chatting with a friend, or doing crosswords or other puzzles
  • If you used to smoke while driving, try something new — try taking public transportation or ride with a friend
  • Take several deep breaths to help you relax
  • Write down your list of reasons for quitting

Remember, quitting may be hard — focus on finding what works for you to manage your cravings.

Get Help

Talk with a doctor, nurse, or pharmacist.

Ask about:

  • Strategies for quitting smoking that are likely to work best for you
  • Medicines that can improve your chances of quitting — and how to use these medicines the right way

When you stop smoking, your body goes through withdrawal from nicotine. This means you may feel irritable, anxious, restless, or hungry. You may even have trouble concentrating or sleeping. Find out about medicines that can help with withdrawal.

What about cost?

Under the Affordable Care Act, insurance plans must cover services to help people quit smoking. Depending on your insurance, you may be able to get these services at no cost to you. Check with your insurance company to find out more. 

Medicare may also cover services to help people quit smoking at no cost. If you have Medicare, learn about Medicare coverage for services to quit smoking

If you don’t have insurance, you may still be able to get free or low-cost services to quit smoking. Find a health center near you and ask about help to quit smoking

Stick with It

Don’t give up!

Remember, it takes time to overcome addiction. Check out these tips for staying smoke-free.

Learn from the past.

Many people try to quit more than once before they succeed. And it’s normal to have slips — especially in the first 3 months after quitting. If you’ve tried to quit before, think about what worked for you and what didn’t.

For example, being around other smokers 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. Remember, quitting is one of the most important things you can do to protect your health.
