What causes smoking dependence?

Simply put, the dependence on smoking is caused by nicotine in tobacco and as nicotine enters the bloodstream and brain smoker. Like oxygen, it passes into the lungs and then into the blood, so smoke and nicotine pass into the lungs and blood of the smoker and then pass through the bloodstream into the brain. Once in the brain, the dependence on smoking is determined by how nicotine works with the brain, creating a physiological change and addiction to nicotine. This is usually strengthened through social and psychological conditioning, in which smoking is further combined with pleasure and relaxation. Nicotine is contained in the tobacco leaf and is a carcinogenic substance that acts as a natural defense of tobacco against insects and other potential infestation. Nicotine passes from tobacco through smoke into a lung or into the mouth of chewing tobacco or non -sinning pipe or smoker of a cigar and then into the bloodstream. Once in the bloodstream, nicotine quickly moves to the brain. Although the first inhalation of a cigarette is accompanied by cough, nevNicotine reached the brain within about 10 seconds and caused a pleasant reaction in about 10 seconds.

In the human brain, nicotine is suitable for nervous receptors, which are usually used by a neurotransmitter called acetylcholine . Acetylcholine is responsible for a number of different neurological chemical processes in the brain, including the release of dopamine and similar stimuli for pleasure. This means that when nicotine reaches a human brain, it triggers an immediate response to pleasure. Continued smoking is introduced when the brain tries to deal with the floods of nicotine by creating many more acetylcholin receptors, which is then able to use nicotine.

However, increasing receptors often requires more nicotine to induce a reaction to pleasure. At this point, the person succumbed to the dependence on smoking and his brain has now made real physiological changes to continue to deal with nicotine. ForThis is often an end to accompanying physical and psychological problems such as headaches, nausea, irritability and mood fluctuations. When leaving, a man literally hungry his brain chemical, which the brain expected as a regular part of everyday traffic.

Smoking addiction is usually further strengthened by psychological and social conditioning, based on smoking association with pleasant activities. When one smokes after every meal, he condition his body to expect a chemical and neurological rush. Once a person is conditional on each meal, he naturally expects to feel the physical effect of nicotine in his system. That is why smoking addiction is so often a social and mental problem, as well as physical, because one teaches his body to combine a chemical reaction with other activities.
