The Basics: 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 the strong feeling that you want to smoke (craving). 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 coworkers for support.

What about cost?
You can get free help with quitting by calling 1-800-QUIT-NOW (1-800-784-8669) and by visiting Smokefree.gov.
As a result of the Affordable Care Act, the health care reform law passed in 2010, insurance plans must cover some 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 what kind of counseling and medicines are included in your plan. For information about other services covered by the Affordable Care Act, visit HealthCare.gov.
Take Action: Stick with It
Don’t give up!
Remember, it takes time to overcome addiction. Check out these tips for staying smokefree.
Learn from the past.
Many people try to quit more than once before they succeed. Most people who start smoking again do so in the first 3 months after quitting. If you’ve tried to quit before, think about what worked for you and what didn’t.
Being around other smokers can make it harder to quit. So can drinking alcohol.
If you are having a hard time "staying quit," 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.
