Are there any drugs that can help quit smoking? Doctor: These kinds of medicines can be used, but you need to follow the doctor's advice!

Do you know why the words "smoking is harmful to health" are printed on the packaging of cigarettes?

　　Because cigarettes clearly know that the person who buys it is addicted, you can't do without it, it can hurt you unscrupulously.

　　Cigarettes are addictive because they contain a lot of nicotine , a neurotoxin that mainly affects the human nervous system. After smoking, there will be transient nervous excitement such as relief of fatigue and refreshment , that is , the pleasure caused by nicotine . After the excitement, the nervous system is then inhibited, which ultimately leads to addiction.

　　You must know that cigarettes are harmful to the body. It has been scientifically confirmed that it is a first-class carcinogen and is closely related to lung cancer . At the same time, it will increase the incidence of various cancers. Not only that, cigarettes can also cause damage to the cardiovascular and cerebrovascular system, which is an independent high-risk factor for hypertension, atherosclerosis, and acute cardiovascular and cerebrovascular diseases .

　　It is also aware of the harm of cigarettes, so more and more people join the army of quitting smoking. However, due to poor personal willpower and not getting rid of the smoking environment, most people fail to quit smoking and enter a dead end of relapse, quitting, and relapse . Therefore, many people pin their hopes on smoking cessation clinics and seek drugs to help them get rid of smoking addiction.

　　So the question is, are there really drugs that can help quit smoking, and which drugs are they?

　　In fact, as early as 2008, the U.S. Public Health Service issued the latest clinical practice guidelines on tobacco use and treatment of dependence.

　　In the content of the guideline, seven first-line clinical smoking cessation drugs that can effectively increase the long-term smoking cessation effect are recommended, including five nicotine replacement therapy smoking cessation drugs and two non-nicotine smoking cessation drugs . In the guidelines, two second-line smoking cessation drugs are also recommended, but so far, these two drugs are rarely used in clinical practice.

　　In China, the drugs that have been approved for smoking cessation are mainly divided into prescription drugs and non-prescription drugs. There are two types of prescription drugs, varenicline and bupropion niacin. Non-prescription drugs mainly include nicotine patches and nicotine chewing gum .

　　The important thing to mention here is prescription drugs. Some related studies have pointed out that varenicline has a significant effect and belongs to the first-line smoking cessation drug . Bupropion hydrochloride is also a fenicotin-based smoking cessation drug that can effectively help smokers quit smoking.

　　The use of combined first-line drugs has been proven to be an effective smoking cessation treatment, which can significantly improve the abstinence rate . But you can't ignore one point, they are all prescription drugs, you can only buy and take them when the doctor prescribes them and meets your physical conditions.

　　Finally, it should be emphasized that in terms of the health benefits of smoking cessation, these drugs are effective treatments that can save lives. Once smoking cessation is successful, it means that the probability of suffering from various cancers and cardiovascular diseases in the future will be significantly reduced. .

　　Of course, smoking cessation requires not only relying on drugs, but also everyone should be clearly aware of the dangers of smoking and have the determination to quit smoking. Only in this way can we get rid of tobacco control.
