Tobacco is one of the most addictive and harmful substances to the human body. People who regularly smoke increase the risk of developing irreversible diseases. The most common damage is to the respiratory system, like pulmonary emphysema, chronic bronchitis and asthma.

In the U.S., 87 % of deaths from lung cancer and 30% of cancer deaths are generally caused by smoking. The other points of the body where this disease occurs, usually because of tobacco, are the mouth, larynx, esophagus, bladder, kidney and pancreas. Smokers tend to suffer from high blood pressure and other cardiovascular problems such as blood clots and aneurysms that can lead to a stroke or a heart attack.

The main threat of tobacco is its addictive nature, whether it is smoked or chewed. Once a person begins to use it, over time it is more difficult to quit, increasing the risk to health. Tobacco also reduces the body's defenses, making people more vulnerable to infections and viruses. It also generates damage to the reproductive system, causing fertility problems.

The many negative effects of cigarette smoking problems include poor healing, loss of sight by macular degeneration, diseases in teeth and gums, decreased sense of smell and taste, and an increase in wrinkles on the skin.

In summary:

Nicotine: is an alkaloid present in tobacco that is quickly absorbed into the bloodstream and stimulates the nervous system, causing a strong dependence on the cigarette. This is the tobacco component that produces addiction.

Tar: is a set of carcinogenic chemicals released via cigarette smoke and are stored in the different parts of the body through which they pass, causing severe damage to health.

Passive smokers: are individuals who, although not directly consuming cigarettes, end up inhaling smoke from people smoking around them and increase their risk of smoking-related diseases.


-The first step to quit smoking is to have a real desire and conviction to do so. Think of your own and your family’s health and wellbeing.

-Smoking is the most preventable cause of death in our society. There are many treatments and support groups to help you quit. Talk with your doctor about which treatment is best for you.

-If you are a smoker and you become pregnant, you should quit immediately because you run the risk of a spontaneous abortion, premature birth or a low birth weight and chronic health problems.

-If you are a passive smoker, ask your family and friends to start treatment for quitting, and avoid being present in enclosed spaces when they are smoking.
