Reversing the Harmful
Effects of Smoking

If you quit, your body will benefit almost immediately.

According to the American Lung Association, nearly 500,000 people die every year from tobacco use and exposure to secondhand smoke.

This makes it the leading cause of preventable death in this country. On top of that, smoking and the use of tobacco products, including cigars and smokeless tobacco, cause or worsen numerous diseases and conditions.

Why? There are more than 7,000 chemicals in a single cigarette, including arsenic, lead and tar. The good news is that if you quit, your body will benefit almost immediately.

How Smoking Affects Your Heart

Researchers with the Centers for Disease Control and Prevention say there are several reasons smoking can be associated with a heart attack. Cigarette smoking can do things like:

  • Raise a type of fat in your blood called triglycerides
  • Lower your “good” cholesterol (HDL)
  • Damage cells that line your blood vessels
  • Increase the buildup of plaque in your blood vessels
  • Cause thickening and narrowing of blood vessels
  • Create blood clots

If smoking does increase plaque buildup in your arteries and cause atherosclerosis it may lead to peripheral arterial disease, which can cause severe pain in your legs and affect your mobility.

Smoking is a major cause of coronary heart disease (also known as coronary artery disease), which can lead to a heart attack.

Your Heart Benefits From Quitting Smoking

According to statistics from the American Heart Association, cigarette smoking is the most important preventable cause of premature death in the United States.

Researchers say the heart-healthy benefits of quitting include:

  • Your heart experiences less stress almost immediately.
  • Your heart rate lowers after about 20 minutes.
  • The amount of carbon monoxide in your blood returns to normal after 12 hours.
  • Heart attack risk decreases after a few months because lungs are healthier.
  • One year after you stop smoking, you have 50% less susceptibility to heart disease.
  • After five to 15 years, stroke and heart disease risks return to those of a lifelong non-smoker.

Use this information to your advantage. Concentrating on the benefits of quitting might just be the motivation you need.

How to Quit Smoking

If you’re going to quit smoking, it helps to have guidance. These are tips to help get you started down the road to a smoke-free life and keep you there. It should include things like:

  • Make the decision to quit.
  • Know your reasons for quitting.
  • Avoid secondhand smoke.
  • Manage your withdrawal symptoms.
  • Build a support group.

The CDC has a lot of information on these recommendations and many others.


According to the American Cancer Society, research shows that using a medication to help you quit smoking can increase your chances of being successful.

There are seven medications approved by the U.S. Food and Drug Administration (FDA) that help people quit smoking safely and effectively. Talk to your doctor about which one is best for you.

Over-the-counter medications that can help ease the symptoms of nicotine withdrawal include:

  • Nicotine gum
  • Nicotine patches
  • Nicotine lozenges

There are four other medications that are available by prescription:

  • Nicotine inhalers
  • Nicotine nasal sprays
  • Zyban (bupropion) – an antidepressant
  • Chantix (varenicline) – a drug that blocks the effects of nicotine in the brain

Talk to your doctor about the most effective way to take these medications. Use them as directed.


Combining counseling with medication makes it even more likely that you will quit smoking and stay away from tobacco for good. Counseling comes in many forms.

  • In-person counseling is available from a doctor, nurse practitioner,  pharmacist, or other healthcare providers.
  • Support groups help many smokers quit. Also, tell your family and friends about your plans to quit, so they can help, too.
  • Telephone quitlines link callers with trained counselors.

The Centers for Disease Control and Prevention lists “Five Reasons Why Calling a Quitline Can Be The Key To Your Success.”


The National Cancer Institute has an app to help you quit smoking. It allows users to do things like:

  • Set quit dates
  • Track financial goals
  • Schedule reminders

It also offers a text messaging service that provides round-the-clock encouragement and advice to people trying to quit.

Cold Turkey

Going cold turkey means that you stop smoking all at once. Gradually smoking fewer cigarettes each day may make it easier to quit. But keep in mind that only 4 to 7 percent of smokers who try to quit cold turkey are successful in staying smoke-free.

One of the most important things researchers have learned about quitting smoking is that the smoker needs to keep trying. It may take several serious attempts before a smoker can quit forever, so don’t be discouraged by relapse.
