Vedclass · Answer

(B) Smoking cigarettes is injurious to health due to the following reasons:$1$. Tobacco contains a large number of chemical substances, including $Nicotine$, an alkaloid.$2$. $Nicotine$ stimulates the adrenal gland to release $Adrenaline$ and $Nor-adrenaline$ into the blood circulation, both of which increase blood pressure and heart rate.$3$. Smoking increases the $Carbon 	ext{ } Monoxide$ $(CO)$ content in the blood and reduces the concentration of haem-bound oxygen, leading to oxygen deficiency in the body.$4$. Smoking is associated with increased incidences of cancers of the lung, urinary bladder, and throat, as well as conditions like bronchitis, emphysema, coronary heart disease, and gastric ulcers.$5$. Tobacco chewing is also linked to an increased risk of cancer of the oral cavity.
