Nicotine addiction

By on July 21, 2015

One of the main causes of high mortality rate world over, explained

In the long run, tobacco has many adverse health effects, due to the way the cigarette smoke damages the whole body.

Lung toxicity

We are talking about one of the most irritant substances for the lungs, because of adhering tar, among other various toxins. By sticking to the lungs, tar will reduce the efficiency of the lungs and the overall capacity to absorb oxygen, therefore other vital organs (like heart and brain) will also not be properly oxygenated. This translates into a general feeling of fatigue that smokers often experience.

In time, smoking damages the lungs due to exposure to carbon monoxide and cyanide. The alveoli lose natural elasticity causing wheezing and bronchitis, which in the end will lead to chronic obstructive pulmonary disease (COPD) or asthma.

Inflicted damages on the Cardiovascular System

Cigarettes have several immediate effects on the heart and blood vessels too:

  • 30% increased heart rate, affecting the heart muscles, which have to work over their capacities in order to ensure necessary blood supply for the organs

  • Carbon monoxide diminishes the oxygen carrying ability of the blood cells

  • The fatigue syndrome will increase, while organs will not receive enough oxygen for proper functioning

  • Blood vessels will narrow, which causes blood pressure to raise, as well as the risk of stroke

High susceptibility to Infections

Smokers are more prone to develop infections like influenza, mucosal lesions, lung infections (bacterial, viral or fungal),meningitis, otitis and even HIV, because nicotine causes structural damages to the tissues and affects the body’s immunity system, which will slowly lose its capacity of defending itself. Due to the reduced immunity level, smokers are also prone to oral and/or lung cancer.

In addition, tobacco damages liver, pancreas, gonads, skin, teeth and can lower life expectancy rate with 10 years. The non-smokers are also affected by the involuntary inhaling of smoke from other people’s cigarettes.

Containing over 4,000 chemicals, including 43 carcinogenic compounds and 400 other toxins, cigarettes harm your health in sometimes irreversible ways. The nicotine, tar, carbon monoxide, formaldehyde, ammonia, hydrogen cyanide, arsenic and DDT poison the body at many different levels. Nicotine is a highly addictive psychoactive drug, which makes quitting smoking very difficult, even for most ambitious and motivated people.

Quitting process

The only way to receive immediate health benefits and avoid or stop the damaging effects of smoking is to quit smoking. Your heart rate and blood pressure will normalize, the oxygen carrying capacity of blood cells will increase and the organs will be normally supplied with oxygen. Your energy levels will boost and the blood circulation will improve. You will notice that your cough will reduce and your senses of smell and taste will come back.

With a positive mind-set and high determination quitting smoking is a very important decision for your well-being. Search for campaigns, medical advice, support guideline and help plans available for patients, in order to improve your health and to extend your life.
