We see many causes and effects of smoking but few are discussed here. There are numerous harmful as well as dangerous effects related to smoking. Carbon monoxide and nicotine in cigarette smoking have been related to several adverse impacts on the lungs and heart. For example, in pregnant women, it can eventually result in grave outcomes including; low birth weight babies, preterm delivery; premature rupture of membranes, placental abnormalities, and increased risk of sudden infant death syndrome. It is pertinent to mention that smoking causes vascular diseases that in turns affect the flow of blood through the placenta. Smokers, in fact, look older than they actually are because the blood vessels are partially obstructed and calcified. The complications resulting from placental abruption are more common in smokers.

Role of CO in smoking:

effects of smoking

As mentioned above, smoking cigarette includes carbon monoxide. Since carbon monoxide is the replacement for oxygen in the blood during smoking, there are some fetuses that could attempt to compensate for this particular deprivation by creating extra red blood cells for the purpose of carrying extra oxygen. In some extraordinary cases, the blood gets thicker from the proliferation of such cells and ultimately cuts off the supply of blood to critical organs with fatal results.

Heart Issue:

heart and smoking

Smoking causes a person’s heart to run in overdrive and ultimately there is a shortage of oxygen in the heart. The heart then has to work more for maintaining supply to the entire human body. The blood vessels are narrowed causing high blood pressure. Moreover, smoking impacts the cardiovascular system of human beings which also becomes a cause of high blood pressure or hypertension. The effect of high blood pressure is heart-related diseases.



Cigarettes contain tobacco which, in turn, possesses nicotine and different other toxic chemicals. These chemicals cause the blood vessel to be narrower than normal. When blood passes through these narrow vessels it creates extra pressure and results in hypertension having some serious effects on the human body including heart strokes and paralysis. Cigarettes cause deterioration in the quality of blood and increase cholesterol level, at times, also creates clots in the heart. The effect of an increased level of cholesterol and the creation of clots in the blood is also heart attack as well as impacting other parts of the body.

CO and Nicotine:


The combination of carbon monoxide and nicotine especially in cigarettes causes increase heart rate and strained heart blood vessels. It cuts off the supply of oxygen to other parts of the human body including hands and feet, and limbs. These causes have grave effects on the entire human body and increase the chances of death. In fact, hundreds of thousands of people die every year, around the world, due to smoking. Smoking is considered as a slow way of death. For example, it causes emphysema that slowly but continuously effects lungs. The effect of emphysema is repeated attacks of bronchitis, lung diseases, and heart failure.

Effects of nicotine:

Nicotine in the blood causes a shortage of oxygen in the human body which, in turn, exerts pressure on the heart. Moreover, it blocks the arteries and causes damage to the blood vessels. The damage affects the flow of blood and increases blood pressure. Chemicals present in tobacco causes damage to the lining of blood vessels that effects fats level and increase the risk of atheroma being a major cause of heart diseases.
