Smoking has become a very common habit among the people these days. It is increasing even among the girls and people of the younger generation who want to try it once. But it just leads to a bad addiction to the cigarette once a person starts smoking. Smoking is very harmful for the health of a person.

It is very injurious to the organs like the lungs in the body. It can cause several respiratory and breathing problems and can lead to cancer in extreme cases when taken in large quantities regularly. The root cause of the addiction of smoking is the nicotine that is present in the cigarette. The nicotine is a very harmful substance that is present in the cigarette. Once consumed, it blends with the blood and makes the person addicted to it. Nicotine is basically an alkaloid that is found in the tobacco. There have been many researches and studies done all of which have clearly shown and proved that nicotine is the addictive ingredient in the cigarette which leads to the bad addiction. It has even been found that the addiction of nicotine is far more than that of even cocaine.

If the use of cigarette is continued for a long time period then the nicotine present in it can lead to several problems including the behavioral problems also. The mechanism behind the nicotine is that it is known to activate the nerves of the central nervous system as soon as it enters the body of the person. After this it binds and sticks to some receptors within the brain of the person depending upon the quantity of usage and frequency of taking it. It then overall causes the whole body to be dependent on it. It basically depends on the amount of nicotine that is going inside your body that leads to the severity of the problems it causes. It is seen that when taken in adequate normal amounts the nicotine sets and goes directly to the brain where it stimulates and hence causes the whole body to relax. This is the reason the person taking cigarette feels good while smoking due to the way his brain acts and makes him feel relaxed and good.

On the other hand if nicotine is taken in larger quantity then it starts triggering some activators in the brain and the body which result in making the body feel totally numb and hence the person now feels lesser pain in all respects. This is the reason it is said that nicotine is highly addictive. This feeling exists only at the time when the person is consuming nicotine and hence after every use of the cigarette the crave rises more and more making the person want it more for the next time. Such is the addiction made by nicotine present in the blood. It is also known to increase the blood pressure of the pressure which is yet another harmful effect caused by nicotine. Therefore we can see from all of the above that nicotine is very harmful and should be avoided and the person should hence quit smoking somehow.
