Alternative Names

Information

If you smoke, you should quit. But quitting can be hard. Most people who have quit smoking have tried at least once, without success, in the past. View any past attempts to quit as a learning experience, not a failure.

There are many reasons to quit using tobacco. Long-term use of tobacco can increase your risk of many serious health problems.

THE BENEFITS OF QUITTING

You may enjoy the following when you quit smoking.

  • Your breath, clothes, and hair will smell better.
  • Your sense of smell will return. Food will taste better.
  • Your fingers and fingernails will slowly appear less yellow.
  • Your stained teeth may slowly become whiter.
