How Smoking Affects the Lungs
Each organ in your body plays an important role in keeping your body healthy. If you have healthy lungs, you probably don’t think much about them. Damage to your lungs, however; can quickly cause a noticeable difference in your ability to breathe easily.
The primary role of the lungs is delivering oxygen-rich blood throughout the body. You breathe in air and breathe out carbon dioxide as waste exhaling. No tobacco product is safe. However, combustible products—those that you burn to smoke—are exceptionally harmful to the lungs.
How does smoking hurt your lungs?
When you smoke, the tissue of the lungs receive damage, impeding them from functioning properly. Smoking also increases your risk of serious health issues. Some examples include: lung cancer, chronic obstructive pulmonary disease (COPD) and emphysema.
Upon your very first puff, immediate damage to the lungs begins. Every puff of cigarette smoke contains over 7,000 chemicals.1 When you inhale, the smoke hits your lungs almost instantly. The blood then carries these toxic chemicals throughout the body. Tobacco smoke contains carbon monoxide, a deadly gas that then displaces the oxygen in your blood. This deprives all your organs of needed oxygen.
What chemicals are found in cigarettes?
Cigarettes also include acrolein. This chemical causes lung damage and a sore throat. Cigarettes may also contain bronchodilators. These chemicals are meant to open up the airways of the lungs. They also can increase the amount of dangerous chemicals absorbed by the lungs.
What are the consequences of smoking?
Cigarette smoke has negative consequences for individuals of all ages. Babies born to mothers that smoked during pregnancy may have abnormal lung development. Teens who smoke may develop weaker lungs which never operate at full capacity or develop to their full, adult size.
Additionally, smoking can destroy the cilia. These tiny hairs in the airway keep dirt and mucus out of your lungs. This may then lead to the development of “smoker’s cough,” a chronic cough common for long-term smokers.
Smokers are also at risk for chronic obstructive pulmonary disease (or COPD). 80% of cases of COPD are due to smoking. 2 People with COPD have difficulty breathing and eventually die because of the lack of oxygen.
COPD has no cure. Moreover, nearly all lung cancer—the top cause of cancer death— is due to smoking. Smokers are 20 times more likely to develop lung cancer than nonsmokers. 3 Lung cancer may also lead to other respiratory cancers.
Are e-cigarettes also harmful?
Because e-cigarettes are still relatively new tobacco products, many do not realize the harm they cause. We discussed this in a recent article “Juuling Much More Dangerous than Teens Realize”.
Some e-cigarette aerosols contain some of the same chemicals as cigarettes. This includes the lung irritant acrolein, and formaldehyde. Some chemicals that create flavor could be harmful when inhaled too. Furthermore, fruit flavored e-cigarettes often large amounts of acrylonitrile, a known respiratory irritant.
Can I reverse the damage of smoking to my lungs?
When you stop smoking, you have overall better health. Lung cancer risk drops drastically in the years after quitting. Furthermore, only 12 hours after quitting, the carbon monoxide level in your blood drops to normal. This, of course, allows more oxygen to circulate to your organs.
