Know your risk

Cigarette smoking causes cancer, heart disease, stroke, lung disease, and chronic obstructive pulmonary disease (COPD). Certain medical conditions or treatments can increase the health risks of smoking.

Childhood cancer: Childhood cancer survivors are at risk for many long-term health problems. Those risks increase with age. By age 50, more than half of childhood cancer survivors have had a serious health problem. These include second cancers as well as diseases of the heart, lungs, and other organs. Cigarette smoking adds to these risks.

Sickle cell disease: People with sickle cell disease are at higher risk for heart and lung problems. Cigarette smoking raises blood pressure and increases the risk of heart disease and stroke. Smoking has also been linked to acute chest syndrome.

Stem cell transplant: Smoking can cause serious problems for people who have had stem cell (bone marrow) transplants. Patients who smoke have an increased risk of death and of developing serious medical conditions such as heart and lung problems.

Create a plan to quit smoking

Quitting smoking is tough. Cigarettes contain nicotine, an addictive drug. For some, smoking is a social activity. Others fear they will gain weight if they quit. Many people smoke to manage stress and anxiety or improve their mood. But smoking can actually make mood symptoms worse in the long run.

Quitting smoking starts with a plan. Give yourself a couple of weeks to get ready. Steps to help you stop smoking include:

  • Set a quit date. Put it on your calendar. Give yourself time to prepare.
  • Make a list of your reasons for quitting. This can help you stay motivated.
  • Plan ways to stay busy and distract from cravings.
  • Tell friends and family so they can support you.
  • Use free resources to help you. If you live in the United States, these are some resources you can use:
    • Call the free 1-800-QUIT-NOW helpline by the Centers for Disease Control and Prevention (CDC) to talk to a coach.
    • Sign up for free text messages at SmokefreeTXT. This National Cancer Institute (NCI) service provides free 24/7 support sent directly to your phone.
    • Use a quit-smoking app. The NCI’s QuitGuide lets you track cravings and slip-ups by time and location.

Identify your smoking triggers

Know what causes the urge to smoke. Make a list of your smoking triggers. These are the people, places, and situations that set off your urge to smoke. They can be:

  • Emotional: Some people smoke when they are in a good mood. Others smoke to relieve stress, reduce boredom, or cope with negative feelings.
  • Routine patterns: Smoking may be tied to certain activities such as watching TV, talking on the phone, or drinking alcohol.
  • Social: A party, event, concert, or bar may spark the urge to smoke.

Avoid triggers as much as possible. Develop a plan for dealing with them if they occur.

Prepare to fight cravings

Nicotine is addictive, and going without cigarettes can cause physical symptoms of nicotine withdrawal. These symptoms will go away in time.

Nicotine cravings are the worst 2–3 days after quitting and usually go away completely 4–6 weeks after quitting. Though they can be intense, they usually only last 3–5 minutes.

It is important to plan ways to fight cravings and use tools and strategies to help you quit. This may include getting support from friends and family, talking with a counselor, or using medications to help you manage nicotine withdrawal.

Ways to help manage cravings include:

  • Go for a walk, exercise, or do other physical activity
  • Chew sugarless gum
  • Keep your hands busy
  • Drink plenty of water
  • Relax with deep breathing, meditation, or other relaxation techniques
  • Distract yourself with an enjoyable activity
  • Spend time with non-smoking friends and family

Consider medicines to help you quit smoking

You can buy the following forms of NRT without a prescription:

  • Skin patch
  • Chewing gum
  • Throat lozenges

These NRT products require a prescription:
