Quitting Smoking

It is possible to get help regarding problems encountered during the process of quitting smoking. In addition to receiving recommendations on behavioral and motivational arrangements aimed at minimizing difficult symptoms of deprivation, you can also benefit from supportive medication recommended by your physician.
In case you have concerns about weight gain on the path to quitting smoking, you can also consult our Nutrition and Dietetics specialists. Psychological support is available to cope with the difficulties of the whole process as well.
Do not think to yourself that you can never quit smoking; that will affect you adversely. Believe in success and be determined.


Nicotine is a highly potent psychological stimulant, so much that it is even more powerful than heroin, cocaine and alcohol when it comes to developing addiction. One out of every 3 people who try smoking for the first time becomes addicted.
Once you start smoking, the nicotine that is absorbed through the cheeks reaches the brain within approximately 10 seconds and causes secretion of some hormones by stimulating the center that is also typically stimulated by substances like heroin and cocaine. These hormones give rise to reward-like sensations like enhanced enjoyment, relaxation and boosted concentration, which in turn further increase the craving for nicotine. As your tolerance to these effects builds up over time, the number of cigarettes you smoke increases gradually. At this point, your body has to take in this substance, even if it does not need it. It can be difficult to manage on your own deprivation-induced feelings such as short temper, tension, disrupted concentration, increased appetite and depression.
Receiving assistance from our Smoking Cessation Polyclinic makes it easier to overcome these impacts.
Within 20 minutes after quitting smoking, your heart rate and blood pressure normalize. Risk of cardiac arrest decreases on day 1. Senses of taste and smell improve 2 days later. By the time it has been 2 weeks, your blood circulation gets regulated. Three months later, pulmonary functions start improving as well. Risks of cardiac disease and lung cancer decrease by half by the end of 1 year and 10 years, respectively. After 15 years, the risk of cardiac disease becomes equal to that of non-smokers.
Deprivation-specific complaints are most prominent during the initial 3 weeks. The most common symptoms of deprivation are restlessness, short temper, sleeplessness and concentration disorder. Two out of every 3 people who quit experience these symptoms. Support offered by the smoking cessation polyclinic (consultancy, nicotine replacement therapy and medical treatment) mitigates these complaints and improves the level of comfort during the process. Quitting thus becomes easier for you. 

It is quite normal for you to experience difficulties while you are quitting smoking. Please do not despair and keep trying. You can consult our “Smoking Cessation Polyclinic” for assistance with regard to difficulties encountered.
E-cigarettes and IQOS products, which heat tobacco instead of burning it, are among the top marketing items and the most recent products of the tobacco industry that primarily target the young population. These products are typically introduced as “less harmful” for the purpose of resuming smoking addiction by replacing tobacco products, which have been proven to have harmful impacts on health. However, these products should not be considered as alternatives for quitting smoking. It should be noted that e-cigarettes also contain carcinogenic and volatile organic components, and cause addiction by imitating the visual aspect and behavior of smoking.
