Even in highly automated plants with their smaller number of workers, decrements in their health and well-being will sooner or later be reflected in impaired productivity or, sometimes, even in disasters. Through governmental legislation and regulation, employers have been made responsible for maintaining the safety of the work environment and work practices, and for the treatment, rehabilitation and compensation of workers with occupational injuries and disease.
Tobacco was ranked 3rd in dependence, 14th in physical harm, and 12th in social harm. Among male smokers, the lifetime risk of developing lung cancer is This risk is significantly lower in nonsmokers: With the postwar rise in popularity of cigarette smoking came a virtual epidemic of lung cancer.
However, if someone stops smoking, then these chances gradually decrease as the damage to their body is repaired.
A year after quitting, the risk of contracting heart disease is half that of a continuing smoker. Risks vary according to the amount of tobacco smoked, with those who smoke more at greater risk.
Smoking so-called "light" cigarettes does not reduce the risk. SCLC may originate from neuroendocrine cells located in the bronchus called Feyrter cells. The corresponding estimates for lifelong nonsmokers are a 1. Chronic obstructive pulmonary disease COPD caused by smoking, is a permanent, incurable often terminal reduction of pulmonary capacity characterised by shortness of breath, wheezing, persistent cough with sputumand damage to the lungs, including emphysema and chronic bronchitis.
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. According to a study by an international team of researcherspeople under 40 are five times more likely to have a heart attack if they smoke.
Furthermore, the ratio of high-density lipoprotein HDL, also known as the "good" cholesterol to low-density lipoprotein LDL, also known as the "bad" cholesterol tends to be lower in smokers compared to non-smokers.
Smoking also raises the levels of fibrinogen and increases platelet production both involved in blood clotting which makes the blood thicker and more likely to clot. Carbon monoxide binds to hemoglobin the oxygen-carrying component in red blood cellsresulting in a much stabler complex than hemoglobin bound with oxygen or carbon dioxide—the result is permanent loss of blood cell functionality.

Blood cells are naturally recycled after a certain period of time, allowing for the creation of new, functional red blood cells. However, if carbon monoxide exposure reaches a certain point before they can be recycled, hypoxia and later death occurs.
All these factors make smokers more at risk of developing various forms of arteriosclerosis hardening of the arteries.
As the arteriosclerosis progresses, blood flows less easily through rigid and narrowed blood vessels, making the blood more likely to form a thrombosis clot. Sudden blockage of a blood vessel may lead to an infarction stroke or heart attack.
However, it is also worth noting that the effects of smoking on the heart may be more subtle. These conditions may develop gradually given the smoking-healing cycle the human body heals itself between periods of smokingand therefore a smoker may develop less significant disorders such as worsening or maintenance of unpleasant dermatological conditions, e.
Smoking also increases blood pressure and weakens blood vessels. Smokers are at a significantly increased risk for chronic kidney disease than non-smokers. Influenza was also more severe in the smokers; Influenza incidence among smokers of 1 to 20 cigarettes daily was intermediate between non-smokers and heavy cigarette smokers.
However, smoking also increases the risk for various other oral diseases, some almost completely exclusive to tobacco users. The National Institutes of Healththrough the National Cancer Institutedetermined in that "cigar smoking causes a variety of cancers including cancers of the oral cavity lip, tongue, mouth, throatesophaguslarynxand lung.
Smokeless tobacco causes gingival recession and white mucosal lesions. Smokers have significantly greater loss of bone height than nonsmokers, and the trend can be extended to pipe smokers to have more bone loss than nonsmokers.
Smoking more than 20 cigarettes a day increases the risk of by two to four times,   and being a current smoker has been linked to a fourfold increase in the risk of invasive disease caused by the pathogenic bacteria Streptococcus pneumoniae.
Also, cigarette smoking interferes with folliculogenesis, embryo transport, endometrial receptivity, endometrial angiogenesisuterine blood flow and the uterine myometrium.
However, the stress levels of adult smokers are slightly higher than those of nonsmokers, adolescent smokers report increasing levels of stress as they develop regular patterns of smoking, and smoking cessation leads to reduced stress.
Far from acting as an aid for mood control, nicotine dependency seems to exacerbate stress.
This is confirmed in the daily mood patterns described by smokers, with normal moods during smoking and worsening moods between cigarettes. Thus, the apparent relaxant effect of smoking only reflects the reversal of the tension and irritability that develop during nicotine depletion.
Dependent smokers need nicotine to remain feeling normal. Generally, the unpleasant symptoms will eventually vanish over time, with repeated use, as the body builds a tolerance to the chemicals in the cigarettes, such as nicotine.
Deprivation reversal also explains much of the arousal data, with deprived smokers being less vigilant and less alert than non-deprived smokers or non-smokers.
Researchers without tobacco lobby influence have concluded the complete opposite: Some writings have stated that smoking can also increase mental concentration ; one study documents a significantly better performance on the normed Advanced Raven Progressive Matrices test after smoking.

The historical roots of meta-analysis can be traced back to 17th century studies of astronomy, while a paper published in by the statistician Karl Pearson in the British Medical Journal which collated data from several studies of typhoid inoculation is seen as the first time a meta-analytic approach was used to aggregate the outcomes .
Smoking is a major cause of premature death worldwide. Despite substantial declines in the prevalence of smoking by adults, estimates based on extrapolation from studies in the s suggest. Smoking is the leading cause of premature, preventable death in this country. Cigarette smoking and exposure to tobacco smoke cause about , premature deaths each year in the United States ().Of those premature deaths, about 36% are from cancer, 39% are from heart disease and stroke, and 24% are from lung disease ().
