Pros and cons of quitting smoking

A person who decides to quit smoking experiences some discomfort at the beginning of a difficult journey. Changes frighten the smoker, so many give up their idea and pick up a cigarette again. The lack of nicotine is manifested by various symptoms that indicate the onset of stress due to quitting tobacco. If the experience of smoking is long, recovery will be painful and long. The process of restructuring is always accompanied by psychological and physical discomfort:

  • Reduced immunity - a former smoker is prone to frequent colds. If earlier nicotine served as doping, then without it the body gets severe stress. Against this background, ARVI, acne, stomatitis, etc. appear;
  • There is an intense cough with brown sputum - you don’t need to be afraid of it, because thanks to coughing, the airways are freed from soot and soot. Over time, the ciliated epithelium resumes its work, pushes out the mucus and sputum that has accumulated in the bronchi;
  • Irritability, nervousness, depression - when nicotine stops entering the body, withdrawal occurs. It lasts for several days. During this period, the former smoker closely follows people who inhale tobacco smoke, he dreams of the whole process, the smell drives him crazy and causes a strong desire to smoke. If earlier nicotine activated pleasure receptors, now their work is inhibited. A person shows aggression, breaks down on loved ones. Relatives should support the former smoker, distract him, interest him in new hobbies. Gradually, the craving will decrease, but the desire to smoke will not go anywhere;
  • Headaches and discomfort in the abdomen appear - within a few weeks the body will be cleansed of nicotine decay products, due to which the functions of all organs and systems are normalized. The absence of nicotine leads to vasospasm, abdominal pain, and impaired stool. Unpleasant symptoms will disappear after 2-3 weeks.

A person who quit smoking feels very hungry, suffers from insomnia, complains of a slow heartbeat. He begins to rush to food, which causes excess weight. All these symptoms are complemented by bad mood and irritability. But there are also benefits to quitting smoking:

Changes in the body by day

Any narcologist will tell you about what happens in the body of a man who has decided to finally get rid of nicotine addiction. Doctors say that the benefits of quitting smoking are very large, but you will have to be patient while the body recovers. The liver produces endogenous nicotine, which maintains normal metabolism. Tobacco nicotine cannot be compared with your own, and it comes in larger quantities. When the level of the substance drops, the body experiences nicotine starvation, demanding a new dose. If it is not possible to get it from the outside, the liver begins to produce endogenous nicotine again. After 3 days, a person can already do without a cigarette, but the cravings still remain.

If we talk about psychological dependence, the situation is more complicated. There are many reasons for the pathological craving for smoking, it can be an innate tendency to addictions, difficulties in communicating with people, a desire not to stand out, etc. It is difficult to get rid of such dependence, and the more experience, the more difficult it will be for a person on the way to a healthy life. The situation is complicated by smoking friends, in whose company you have to constantly be. In order not to seem like a "white crow", many people again inhale harmful smoke, such a craving lasts for years and does not let go of a person. A psychotherapist will help get rid of it, who will find out the causes of pathological addiction and will be able to motivate the patient.
