Effects of Smoking

10 effects of smoking on the body: Irritation of the trachea (windpipe) and larynx (voice box)

Reduced lung function and breathlessness due to swelling and narrowing of the lung airways and excess mucus in the lung passages

Impairment of the lungs’ clearance system, leading to the build-up of poisonous substances, which results in lung irritation and damage Increased risk of lung infection and symptoms such as coughing and wheezing

Permanent damage to the air sacs of the lungs.

Raised blood pressure and heart rate

Constriction (tightening) of blood vessels in the skin, resulting in a drop in skin temperature

Less oxygen carried by the blood Stickier blood, which is more prone to clotting

Damage to the lining of the arteries, which is thought to be a contributing factor to atherosclerosis (the build-up of fatty deposits on the artery walls)

Reduced blood flow to extremities like fingers and toes Increased risk of stroke and heart attack due to blockages of the blood supply. (

Illnesses are more severe and it takes longer to get over them.

Cancer is the second leading cause of death and was among the first diseases causally linked to smoking. (

Smoking's effects on the lungs, such as the development of emphysema and lung cancer, are mainly caused by tar and nicotine. (

Smoking makes the blood more likely to clot. These clots can travel in your bloodstream until they finally become stuck in one of the blood vessels in your brain, cutting off blood flow and triggering a stroke. (

People who smoke have a two to four times higher chance of having heart disease. (

Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases. It makes it difficult to breathe. There are two main forms of COPD:

Chronic bronchitis, which involves a long-term cough with mucus

Emphysema, which involves destruction of the lungs over time
