Cigarette smoking damages almost every organ of the body, causes many diseases, and reduces the health of smokers in general. We take a closer look at the health risks from smoking, and look at some tips and tools you, or a loved one, can use to quit smoking for good.
Smoking and your health
Smoking damages almost every organ of the body and affects a person’s overall health. It is a prime cause of lung cancer but is also a known risk factor for cancer in many parts of the body, including:
- Colon and rectum
- Kidney and ureter
- Trachea, bronchus, and lung
Smoking damages the heart in several ways. The carbon monoxide in tobacco smoke reduces the amount of oxygen in blood, and may contribute to the development of coronary heart disease and possible heart attacks.
Smoking also damages the lining of arteries, leading to a build-up of fatty material (atheroma) which narrows the artery and reduces blood flow to the heart, this can cause angina or a heart attack.
Chronic obstructive pulmonary disease
Cigarette smoke damages the tissues of the lungs, leading to overproduction of mucus. Chronic bronchitis occurs when the airways in your lungs have become narrow and partly clogged with mucus.
People who suffer from chronic bronchitis cough more, experience breathlessness and are also more at risk of developing chest infections and pneumonia.
Tobacco smoke also damages the air sacs in the lungs. Over time this leads to progressive loss of lung function and a condition known as emphysema. As the disease progresses, breathing becomes a major effort and may require supplementary oxygen.

Why do smokers continue to smoke?
The health risks and associated consequences of smoking are well documented, yet there are over 1 billion smokers globally and every day approximately 15 billion cigarettes are sold.
Knowing the reasons why you continue to smoke, can help you quit.
The primary reason smokers continue to smoke is addiction. Cigarettes contain nicotine, a highly addictive substance found naturally in tobacco. It travels quickly to the brain when it is inhaled, causing a feeling of relaxation.
The relaxing effects from nicotine are temporary. When the body rids itself of nicotine, it experiences withdrawal and craves another cigarette. Creating a cycle of dependency.
Nicotine withdrawal symptoms include:
Many smokers use cigarettes as a stress reliever and an aid to help them cope in difficult situations, however nicotine can actually increase stress and cause agitation. Nicotine cravings cause additional stress as your body experiences withdrawal.
It’s important to look for healthy ways to handle stress and take care of yourself without smoking.

Smoking cessation tips

Everyone will have their own reasons for wanting to quit, it could be guilt at the thought of not being around for your family or simply wanting to look and feel younger.

10. Keep trying
E-cigarettes are battery-operated smoking devices which heat the liquid in cartridges filled with chemicals, and convert it into a vapor that's inhaled by the user.
Although they do not produce tobacco smoke, e-cigarettes still contain nicotine and other potentially harmful chemicals.
While several studies have found that e-cigarettes produce lower levels of carcinogens when compared to smoke emitted by traditional cigarettes, very little is really known about the health risks of using them.
Due to the lack of scientific evidence on the health effects of using e-cigarettes, for now, they cannot be recommended as a safe and helpful way to quit smoking.
Quitting smoking is hard. The path to becoming a non-smoker is different for each individual and can be difficult. It requires perseverance, commitment and an abundance of will power. However, thousands of people successfully quit smoking every day.
If you are a smoker, right now is a great time to quit. By tomorrow you’ll already start to feel the benefits.
If you have questions about the effects of smoking or would like some advice on quitting, talk to your doctor.
