La trompeta After the terrorist attacks of September 11,

2001, the U.S. launched the "war on terror", a

campaign battle that has lasted more than a

decade. 11 years ago, on October 7, 2001, the

United States launched Operation Enduring

Freedom, which became the war in

Afghanistan, and in March 2003 he attacked

Iraq. Thousands of Americans have died and

nearly 50,000 soldiers have been wounded in

these wars

The harms caused by using tobacco include diseases affecting the heart and lungs, with smoking being a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD), emphysema, and cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancers).

Mortality

Male and female smokers lose an average of 13.2 and 14.5 years of life, respectively.

Cancer

The primary risks of tobacco usage include many forms of cancer, particularly lung cancer, kidney cancer, cancer of the larynx and head and neck, breast cancer, bladder cancer, cancer of the esophagus, cancer of the pancreas and stomach cancer.

Pulmonary

Since establishing causation through experimental trials was not possible due to ethical restrictions, a lengthy study was conducted in order to establish the strong association necessary to allow for legislative action against tobacco consumption.

In smoking, long term exposure to compounds found in the smoke (e.g., carbon monoxide and cyanide) are believed to be responsible for pulmonary damage and for loss of elasticity in the alveoli, leading to emphysema and COPD.

Cardiovascular

Smoking can cause atherosclerosisleading to coronary artery disease andperipheral arterial disease.Tobacco stains on primarily the 2nd and 3rd fingers in

Inhalation of tobacco smoke causes several immediate responses within the heart and blood vessels. Within one minute the heart rate begins to rise, increasing by as much as 30 percent during the first 10 minutes of smoking. Carbon monoxide in tobacco smoke exerts its negative effects by reducing the blood’s ability to carry oxygen. Both of these conditions can become permanent with prolonged use of cigarettes.

Second hand smoke

second-hand smoke is a mixture of smoke from the burning end of a cigarette, pipe or cigar and the smoke exhaled from the lungs of smokers. It is involuntarily inhaled, lingers in the air hours after cigarettes have been extinguished, and can cause a wide range of adverse health effects, including cancer, respiratory infections and asthma. Non-smokers who are exposed to second-hand smoke at home or work increase their heart disease risk by 25–30% and their lung cancer risk by 20–30%. Second-hand smoke has been estimated to cause 38,000 deaths per year, of which 3,400 are deaths from lung cancer in non-smokers.
