Do you think you lack willpower? Willpower has nothing to do with it -
it's all about the physiology of the brain
. When we smoke, nicotine from cigarette smoke enters the lungs, is absorbed into the pulmonary veins, then into the arteries, and from there it enters the brain. There are nicotine sensitive receptors in the brain. In fact, normally the task of these receptors is to control the work of the body, including mood and thinking. But when nicotine enters the business, the brain’s work is not only disturbed, but significantly changes.
Under the influence of nicotine, receptors release dopamine, which is involved in the reward system, glutamate is the main stimulating neurotransmitter in the brain, as well as serotonin, adrenaline and norepinephrine. As a result, after "smoking" for some time it is easier to think, concentrate on work tasks, the smoker becomes calmer and more resistant to stress.
One problem: nicotine-sensitive receptors “clog” very quickly and stop responding to stimulation with a cigarette. That is, only the first morning puff is really happy. Then smokers pick up a cigarette, just to avoid nervousness, irritability and an obsessive desire to pause and finally smoke.
The more a person smokes, the sooner a nicotine addiction is formed, with each new cigarette additionally supporting tobacco cravings. In fact, nicotine is integrated into the system that regulates the functioning of the brain - so firmly that the suffering of a brain devoid of a cigarette is clearly visible on functional magnetic resonance imaging (f-MRI).
Naturally, in such a situation it will be very difficult to quit smoking even for a person with a steel will. After all, in fact, in the fight against nicotine, you have to play against your own brain, which is configured to resist with all its might.
