It is without doubt that smoking is an extremely harmful habit that is the main cause of 90% of cancer fatalities. There are over 1.1 billion people in the world who smoke and 50% will succumb to lung cancer because of inhaling toxic substances to the tune of almost 7000 of them existing in tobacco like arsenic and carbon monoxide (which displaces oxygen from hemoglobin preventing the flow of oxygen in the blood), butane, and even minute glass particles that can cut the lungs just to improve the delivery of nicotine.
Nicotine is the main cause of lung issues
The main causes of lung issues are the inhalation of all these harmful substances which result in chronic obstructive pulmonary disease and lung cancer. It can also lead to sever plaque deposits in arteries resulting in heart disease, congestive heart failure and ultimately heart attacks due to damaged heart and blood vessels.
Nicotine increases the stress hormone
Nicotine increases the stress hormone cortisol in the body which is bad for the immune system and can even lead to autoimmune disease. Smoking also leads to several other negative issues like insomnia, infertility, hormonal imbalances, blood sugar problems, gastrointestinal problems, and osteoporosis. In many people, nicotine becomes addictive and will cause withdrawal symptoms when you try to stop.
Smoking reduces levels of essential nutrients
Withdrawal symptoms from nicotine may cause irritability, and edginess. The addiction to nicotine is even more powerful than to drugs like cocaine as pointed out by users. But it is worth the ultimate result because smoking reduces essential nutrients and antioxidants in our blood like vitamin C, E, glutathione, ubiquinol, alpha-lipoic acid, and beta-carotene. It is also interesting to note that supplementation will not counter the effects of nicotine intake.
