Deadly health effects of tobacco consumption

The issue of tobacco use is a worrisome problem in our society. There is an estimate of over 1 billion smokers in the world today and the number is still increasing. Smoking is not only hazardous to an individual’s health, it is also hazardous to people around the individual who can be referred to as
involuntary smokers, that is persons that are forced to inhale second hand smoke. The fact that smoking kills thousands of people every year both first hand and second hand smokers is an issue to be taken seriously.


Studies have attributed smoking to be the major cause of lung cancer. In a normal circumstance, the lungs’ air passages contain millions of tiny hairs called cilia. These tiny hairs act like brooms protecting the air tubes by removing dust particles, tar, and other foreign materials. Every time an individual smokes, this tobacco smoke hits these tiny hairs make them to slow down and soon stop moving. Because of this, the trapped tar from the tobacco begins to accumulate into the cells lining the air tubes. Over time, the constant irritation turns some of the cells cancerous.

However, lung cancer is not the leading cause of death in smokers. Smoking is also responsible for over 1 million strokes and heart attacks each year. The carbon monoxide and nicotine in tobacco are the leading cause of vascular diseases. Carbon monoxide interferes with the ability of the red blood cells to carry oxygen. This results in narrowing and hardening of the arteries, shortness of breath etc. The nicotine in tobacco engages small arteries depriving major organs of the body like the lungs, heart and the brain of essential oxygen. Nicotine is also addictive and it produces a sense of well being and relaxation.

Other health issues caused by smoking. These include the following:

  • Smokers are more likely to suffer ulcers of the stomach and duodenum. 
  • Women that smoke during pregnancy endanger the lives of their unborn kids. This may lead to mental retardation, physical disability, high mortality rate etc. 
  • Smokers are more likely to have cancer of the mouth, bladder, kidneys, oesophagus and cervix than non smokers. 
  • Smoking in some cases pulls calcium out of the skeleton, thereby speeding up bone thinning process often referred to asosteoporosis. 
  • Smoking causes the destruction of lung tissue, producing death by suffocation. 


It has been noted that individuals who quit smoking begin to recover immediately. This is because the nicotine and the carbon monoxide begin to leave the body and this reduces the probability those other diseases which are related to smoking will occur. Benefits of quitting smoking include improved health and energy, increased self esteem, better breathing etc. Reasons why an individual must abandon the habit of smoking can be outlined as follows:

  1. It reduces the risk posed to the smoker’s family, relatives and friends from second hand smoke. 
  2. Reduces the risk of osteoporosis.
  3. Reduces the likelihood that the smoker’s children will smoke in the future. 
  4. Whiter teeth, fewer wrinkles and better breath. 
  5. Reduces the risk of heart disease, stroke, cancer of the mouth, throat, pancreas, kidneys, bladder etc.
  6. Quitting smoking reduces or lowers insurance and medical
