Is E-Liquid Harmful to Your Health?

Is e-liquid harmful to health? Tobacco poses a threat to each of us, both in terms of health and economics. Currently, approximately 6 million people die each year due to tobacco use, and if no action is taken, this number is expected to rise to over 8 million annually by 2030. Tobacco use poses a threat to anyone, regardless of gender, age, race, culture, or educational background.

The use of tobacco brings suffering, disease, and death, plunging families into poverty and weakening national economies. Smokers' physical conditions, such as strength, agility, coordination, gait, thinking, reaction, living ability, and balance, are far inferior to those of non-smokers. Health experts point out that smoking is harmful to health, and it can be said to have countless harms with no benefits, with conclusive evidence.

For anyone, at any time, quitting smoking or staying away from tobacco is a positive and effective lifestyle intervention. The side effects of smoking and tobacco consumption in China are significant, and the government has invested heavily in anti-smoking campaigns.

However, it is regrettable that China has made little progress in promoting tobacco control, as the growth of smokers and tobacco consumption has not been effectively controlled, in stark contrast to the efficient control seen in Western countries. This directly leads to health destruction and financial drain for the relevant population, which is also the original intention of the Chinese government to strengthen tobacco control.

Why is quitting smoking and controlling tobacco so difficult?

First, let's analyze it from a medical perspective. For smokers, smoking is not just a habit; more importantly, it is a manifestation of an irresistible nicotine addiction. After smoking, nicotine quickly acts on the a4b2 receptors located in the ventral tegmental area of the brain, activating the receptors to release "dopamine." Dopamine acts like an excitement sprite, generating various pleasurable feelings in the brain; when absent, it causes irritability, discomfort, nausea, headaches, and a craving for nicotine. Once nicotine is replenished, dopamine is rapidly released again, and the smoker feels pleasure once more, forming a "reward circuit" of nicotine dependence in the brain. This is nicotine dependence, also known as nicotine addiction, which is a psychological disease. Habits and addictions are very difficult to change, which is one reason why quitting smoking is challenging.

Secondly, smoking exists as a social subculture. Throughout history, tobacco has served as a mysterious guide to human spiritual life; it can be seen as a communication tool between the divine and humans, as well as a means of connecting daily life with the spiritual world. Similarly, today, cigarettes are often viewed as a spiritual refuge, another door to escape daily boredom and monotony. Cigarettes have transformed into a symbolic carrier for individuals to indulge in their own spiritual world and self-release. Regardless of how this symbolic structure is formed, its social function has never disappeared, which is the cultural root of the difficulty in eradicating smoking.

The Rise of E-Cigarettes

E-cigarettes are electronic products that mimic traditional cigarettes, having the same appearance, smoke, taste, and feel. They utilize microcomputers and other electronic components to atomize nicotine and other substances into vapor for users to inhale, while the exhaled vapor resembles real cigarette smoke, thus satisfying the physiological and psychological needs identical to those of traditional cigarette smoking. E-cigarettes, due to their lack of highly carcinogenic tar and relatively low toxicity, are regarded as a substitute for cigarettes and are recommended by doctors as a smoking cessation method; the specific approach is to gradually reduce nicotine intake, thereby slowly decreasing the demand for nicotine, ultimately achieving the goal of quitting smoking. This is an ideal method; however, its popularity is largely unrelated to this, as it is more often treated as a trendy toy.

Currently, the global sales of e-cigarettes are enormous, with a compound annual growth rate of 51% over the past five years. In 2015, sales reached $8 billion, and the market potential in China is vast. This indicates that the rise of e-cigarettes is becoming a new industry with a significant impact. However, due to their popularity, the dangers are also substantial.

The Dangers of E-Cigarettes

The World Health Organization has conducted research on e-cigarettes and reached a clear conclusion: e-cigarettes are harmful to public health and are not a smoking cessation method; regulation must be strengthened to prevent harm to adolescents and non-smokers.

Everyone knows that the reason for nicotine addiction is that cigarettes contain nicotine. The large amounts of tar and carcinogens produced during the combustion of cigarettes are the greatest harm of smoking! The small amount of nicotine in cigarettes does not cause significant harm to the human body. In fact, this is a misconception; although nicotine has low carcinogenicity, it is closely related to arterial sclerosis, which is a major cause of cardiovascular diseases.

How Does Smoking Lead to Arterial Sclerosis? Even Cardiovascular Diseases?

1. Nicotine can damage endothelial cells in blood vessels, which some people vividly describe as "a knife on blood vessels," ultimately leading to vascular hardening.

2. Nicotine can increase the secretion of adrenaline and norepinephrine, causing an increased heart rate, vascular constriction, and increased myocardial oxygen consumption; it also causes the small blood vessels in the limbs to spasm and narrow, leading to increased blood pressure. Over time, this results in thickening of the vascular walls and the formation of atherosclerosis with narrowing. Nicotine is recognized as a major harmful factor causing atherosclerosis in cardiovascular diseases.

3. Nicotine interferes with fat metabolism. Nicotine can reduce high-density lipoprotein and increase low-density lipoprotein.

4. Nicotine can promote red blood cell aggregation and white blood cell deposition, increasing blood viscosity, slowing blood flow, and causing thrombosis.

This is a significant danger that e-cigarette promoters or users have not paid enough attention to: because e-cigarettes are recommended as smoking cessation aids (helping smokers smoothly transition through the psychological dependency period), they require people to actively reduce nicotine content gradually; however, in fact, the success rate of quitting smoking through this method has not significantly increased. On the contrary, people treat it as a new type of tobacco, adding more flavors and variations to attract both smokers and non-smokers; today, this novel toy has attracted a large number of young people's attention.
