True. Smoking tobacco is one of the most common avoidable causes of illness and death in most countries. 

True. Nicotine, carbon monoxide and other harmful chemicals from the burning tobacco travel in the mother s bloodstream and can reach the foetus. This can result in impaired development and reduced birth weight. Tobacco smoke can also be harmful to young children and babies (sudden infant death syndrome). 

The World Heath Organisation has stated that cigarette smoking is the single most preventable cause of death in the world. Explain why breathing in tobacco smoke is so lethal. 

Acute Respiratory Infection (ARI), as pneumonia, is one of the biggest causes of death for young children in the Asian region. ARI is also responsible for more episodes of illness than any other disease, with the exception of diarrhoea, and it is well known that ARI is aggravated by exposure to pollutants and indoor environmental tobacco smoke (ETS). 

The other specific causes of death which are shown on Table I (coronary disease, stroke, accidents and suicide) are known to be related to alcohol or tobacco use. However, for fatal coronary disease, which is the major killer in this country, the risk among... 

The nervous system is the most sensitive target for cyanide toxicity, partly because of its high metabolic demands. High doses of cyanide can result in death via central nervous system effects, which can cause respiratory arrest. In humans, chronic low-level cyanide exposure through cassava consumption (and possibly through tobacco smoke inhalation) has been associated with tropical neuropathy, tobacco amblyopia, and Leber s hereditary optic atrophy. It has been suggested that defects in the metabolic conversion of cyanide to thiocyanate, as well as nutritional deficiencies of protein and vitamin B12 and other vitamins and minerals may play a role in the development of these disorders (Wilson 1965). 

While gender roles and norms in some parts of the world have discouraged women from smoking, smokeless tobacco is more acceptable in some regions (e.g., Africa, India), and waterpipes in others (Middle East). Smokeless tobacco is responsible for four million deaths per year worldwide half of these are among women this is predicted to increase to 10 million deaths per year by 2030 (Christotides 2003). In contrast to India, women in the United States are much more likely to smoke cigarettes than to use smokeless tobacco. 

Tobacco use continues to be a major cause of preventable death. Although the number of smokers is gradually decreasing in developed countries, the remaining hard-core smokers are becoming harder to treat. Additionally, the decline has been less pronounced in women than in men (Fiore 1992). Another important concern for society is adolescent smokers. In the USA, in 2006, tobacco use among males above the age of 12 was higher than females (36.4 vs. 23.3%). On the other hand, the rate of...
