Smoking has many serious health risks, and medical professionals must take responsibility for discouraging and helping smokers to quit. Smoking is a complex, social behavior that often involves drug dependence, and quitting is a comprehensive, multifaceted behavior modification. First, analysis and understanding of the smoker’s motivation or reasons for smoking is the basis for developing an individualized cessation program. Smokers usually start smoking because of the influence of the external environment, such as parents’ smoking, friends’ encouragement, social toasting, adolescent imitation, and curiosity. Some smokers repeat the action of smoking day after day, year after year, smoking has become a habitual behavior of smokers, forming a conditioned reflex, that is, the habit of smoking is completely dissolved into daily life and work. Therefore, special attention should be paid to the correction of the psychological addiction of smokers in the cessation of smoking. The factor that gives smokers psychological pleasure is the nicotine in tobacco, which is an addictive substance with similar effects to morphine and cocaine. Smoking addicts have a strong craving for tobacco, the essence of which is drug dependence. Nicotine receptors exist on the cholinergic neurons of the central nervous system, and nicotine in tobacco combines with nicotine receptors to change the normal physiological state of the body, and over time the receptor level (number, sensitivity) changes, forming nicotine dependence, and once you stop smoking, you will experience cravings, anxiety, dizziness, headache, inattention, appetite and heart rate, cortisol and adrenaline secretion changes and a series of mental, psychological and physiological changes, this is withdrawal symptoms. Another aspect of nicotine addiction is the ease with which smokers can return to smoking after quitting, similar to what happens after quitting alcohol or drug treatment. If smokers are helped to release the pharmacological effects of nicotine (drug addiction), it is important for successful cessation. In addition, promotional media directly influence tobacco consumption and social smoking behavior. Tobacco advertising and promotions portray smoking as a socially normative behavior, creating the illusion that smoking is harmless and socially desirable, which contributes to an increase in the number and quantity of smokers. Based on the above analysis of the causes and effects of smoking, individualized cessation programs for smokers can be developed. The first step in helping to quit smoking is to understand the smoker’s smoking status and to broadly categorize the smoker. In general, the doctor can determine the type of smoker by asking two simple questions: 1. “Do you smoke within half an hour of waking up in the morning?” or “What is the first thing you want to do in the morning (smoke)?” , 2. “Do you smoke more than 25 cigarettes a day?” . If the answer to both questions is yes, then the smoker is more heavily dependent on nicotine. For smokers without nicotine dependence, the key is to apply various methods to make them deeply aware of the dangers of tobacco and therefore strongly motivated to quit. On this basis, some smokers can be motivated to quit through self-restraint and the issuance of cessation manuals, but the success rate of quitting smoking through these methods alone is not high. It has been shown that physician counseling has an important impact on the psychological and behavioral well-being of smokers. Serious and repeated advice from a doctor about the consequences of smoking and the benefits of quitting, especially in the context of the smoker’s own health, can go a long way toward increasing the smoker’s commitment and self-awareness. The success rate of smoking cessation is expected to be increased if the smoker visits the clinic regularly for further guidance and if exhaled breath carbon monoxide measurements are used to help the doctor objectively understand the smoker’s recent smoking status. In addition to counseling, physicians should also provide behavioral therapy to smokers. It is generally estimated that if physician counseling can lead to 10% of smokers successfully quitting, behavioral therapy can increase the quit rate to 20%. Doctors can help smokers change their past patterns of smoking-related behavior through lectures, smoking cessation classes, or individual counseling, and can design a phased program for smokers to quit. For those who quit, a relapse prevention program needs to be developed at the same time. For those who fail, it is important to help them analyze the reasons for their failure, encourage them to quit again, and combine behavioral therapy with pharmacotherapy if necessary. The main problem in implementing behavioral therapy is that smokers have difficulty attending lectures and classes on time, and that providing individualized behavioral instruction to each patient can take a lot of time from the physician or cessation worker. For smokers with nicotine dependence, these methods are often unsuccessful. These smokers often need to be treated with medication. Nicotine replacement therapy is effective in that it allows the person who wants to quit to reduce physical withdrawal symptoms with nicotine replacement while struggling with their smoking habit and psychological addiction. The dose of nicotine given is gradually reduced in the cessation so that the process of quitting smoking is successfully completed. Commonly used nicotine preparations are nicotine transdermal patch and nicotine oral gum two, nicotine spray is still in the experimental stage. The nicotine in the transdermal patch is stably absorbed through the skin and maintained at a certain level in the body (about 50% of the level when smoking). The transdermal patch is generally used for 8-12 weeks, with sufficient doses of nicotine to reduce withdrawal symptoms for the first 4-6 weeks, and then the dose of nicotine in the patch is gradually reduced until it is discontinued for the next 4-6 weeks. Nicotine transdermal patch side effects are very small, common only to the skin irritation caused by local skin redness, but does not affect the replacement site to continue to use the drug, a small number of people using transdermal patch skin sensitization. Nicotine oral gum can slowly release nicotine in the chewing process (chewing 20-30 minutes, can release about 90% of the nicotine). The recommended duration of use is 3 months, but a significant proportion of ex-smokers actually need to use it for longer. Nicotine transdermal patches and nicotine oral gum can sometimes be used in combination to increase effectiveness. The effectiveness of different nicotine preparations for smoking cessation varies, but in general terms. Nicotine replacement therapy can increase smoking cessation success by more than a factor of one compared to when the drug is not used. There are two issues to keep in mind when using nicotine replacement therapy: first, it should be used in combination with other smoking cessation methods; second, be aware that long-term use of nicotine preparations may also lead to nicotine addiction. Other pharmacological treatments include colistin, antidepressants, anxiolytics and nicotine antagonists, but their effectiveness has not been determined. The use of acupuncture and hypnosis to help quit smoking has also been reported, but their effects and effectiveness need to be further explored. Smoking cessation is a complex process, and physicians should help smokers complete it from multiple perspectives, including social, psychological, and physical, in order to protect their physical health.
