How Does Tobacco Affect Your Immune System?


Tobacco smoke is a deadly mix of more than 7,000 chemicals. Many of these chemicals are harmful and can damage your lungs, heart, and other organs in your body. But what about your immune system? How does tobacco smoke affect your immune system?

In this article, we will discuss the effects of tobacco smoke on the immune system and how it can make you more susceptible to illness.

How Does Smoking Affect Your Immune System?

Your immune system is a complex network of cells and organs that work together to protect your body from foreign invaders, such as viruses and bacteria. When working properly, your immune system can help fight off infections and diseases.

However, tobacco smoke can weaken your immune system and make it less able to fight off infection. This is because tobacco smoke contains harmful chemicals that can damage the cells in your body, including the cells in your immune system.

Tobacco and its smoke is loaded with more than 7000 chemical components. All these impact the immune system, and reduce the body’s natural capacity of fighting diseases.

How Does Tobacco Affect Your Immune System?

#1 – Nicotine

One of the most well-known effects of nicotine is that it acts as a stimulant. It gives you that “kick” or burst of energy and alertness. But what many people don’t know is that nicotine also suppresses the immune system.

In fact, studies have shown that smokers are more likely to get infections than nonsmokers. They’re also more likely to have a harder time fighting off those infections.

One of the ways nicotine suppresses the immune system is by reducing the number of certain types of immune cells, like T-cells and natural killer cells.

These are the cells that help your body fight off viruses, bacteria, and other foreign invaders.

Nicotine also increases the levels of stress hormones in your body. These hormones can further suppress the immune system.

#2 – Tar

Smoking tobacco creates a solid chemical substance called tar.

This sticky substance is made up of hundreds of different chemicals, including some that are known to cause cancer.

When you breathe in tar, it coats your lungs and airways. Over time, this can damage these tissues and make it harder for you to breathe. It can also lead to lung diseases like emphysema and bronchitis.

Tar can also weaken your immune system by damaging the cells that line your airways. These cells are important because they help keep germs from getting into your lungs. When they’re damaged, you’re more likely to get sick.

#3 – Oxidizing chemicals

Smoke from cigarettes also contains oxidizing chemicals. These are substances that can damage cells in your body.

They can make it harder for your immune system to fight off infections.

Oxidizing chemicals can also damage the DNA in your cells. This damage can lead to cancer.

Cigarette smoke also contains metals like cadmium and lead. These metals can damage your lungs and other organs.

They can also make it harder for your body to absorb important vitamins and minerals.

All of these effects work together to weaken your immune system and make you more likely to get sick.

#4 – Carbon monoxide

If consumed in large doses, as in smoking over the years, carbon monoxide replaces the oxygen in your blood, causing early death.

It is one of the most dangerous chemicals in tobacco smoke. It can also cause heart disease, because it makes your blood carry less oxygen.

This can lead to a heart attack or stroke. Carbon monoxide is just one more way that smoking harms your immune system.

#5 – Radioactive components and metals

Tobacco plants absorb some of the radioactive materials and metals from the soil where they are grown.

When you smoke tobacco, these harmful substances enter your body along with nicotine. They can damage cells and make it harder for your body to repair itself.

Smoking also exposes you to cadmium, which is a metal found in batteries. It is linked to kidney disease and lung cancer.

These are just a few of the many harmful substances in tobacco smoke that can damage your immune system. Quitting smoking is the best way to protect yourself from these dangers.

What Are The Major Diseases Caused By Smoking?

Cigarette smoking is a major cause of disease in the United States. Smoking is linked to 87% of lung cancer cases, and is also a major contributor to heart disease, stroke, and other respiratory diseases.

Smoking causes an estimated 480,000 deaths in the United States each year—that’s about one in five deaths.

Cigarette smoking is estimated to cost the United States more than $300 billion each year in direct medical care and lost productivity.

How To Improve Your Immune System After Quitting Smoking?

Now that you have finally quit smoking, you are likely wondering how to improve your immune system.

Quitting smoking is definitely a positive step for your health, but it is also important to make sure that you are doing everything possible to boost your immune system.

One of the best things that you can do for your immune system is to improve your diet.

Eating a healthy diet full of fruits, vegetables, and whole grains will help to boost your immune system.

In addition, you should also make sure that you are getting enough protein. Protein is important for repairing and rebuilding your immune system.

#2 – Exercise

Another great way to boost your immune system is to exercise.

Exercise helps to increase the production of white blood cells, which are important for fighting off infection.

In addition, exercise also helps to reduce stress, which can also weaken your immune system.

#3 – Vitamin D

Getting sufficient amounts of Vitamin D will boost your immune system.

Vitamin D helps to regulate the immune system and helps to fight off infection.

You can get Vitamin D from exposure to sunlight or from taking supplements.

If you do not get enough Vitamin D, you may be at risk for developing infections, such as respiratory tract infections.

#4 – Start a supplement regimen

There are many different supplements that can help to boost your immune system.

Some of the most popular supplements include: Vitamin C, Zinc, and Echinacea.

These supplements can help to increase the production of white blood cells and help to fight off infection.

You should talk to your doctor before starting any supplement regimen.


The bottom line is that smoking tobacco can have a significant negative impact on your immune system, making it harder for you to fight off infection and disease.

If you’re trying to quit smoking, it’s important to remember that the health of your immune system is at stake. You can find helpful information and support from resources like the Centers for Disease Control and Prevention (CDC).

Remember, quitting smoking isn’t easy, but it’s worth it for your health! Have you been able to successfully quit smoking? What tips would you share with others who are trying to quit?
