Why is e-cigarette smoking addictive?

A recent study found that e-cigarettes can also cause some very serious problems. The liquid in e-cigarettes contains the addictive substance nicotine, and many e-cigarettes have incorrect drug concentration labels. Another study showed that gradually reducing the nicotine content will not help people quit smoking successfully. Among all the subjects in the study, only one person successfully quit smoking after a year of effort.

A research team composed of the American University of Beirut and the Center for the Study of Tobacco Products recently conducted a study to explore the nicotine content and type of nicotine in e-liquid. Among the three types of nicotine, after testing the e-liquid of all brands of e-cigarettes, researchers found that they all contained the most toxic type of nicotine - free nicotine, and this type of nicotine is very easily absorbed by the human body. What is more noteworthy is that the nicotine content in e-cigarette liquids often does not match the label. Prior to this, relevant experts believed that the World Health Organization's report on e-cigarettes was wrong.

According to the results of an independent two-year investigation, reducing the nicotine content in cigarettes does not help people quit smoking. "We are not sure whether low-nicotine cigarettes can help smokers reduce their nicotine dependence or help them quit smoking," said Dr. Neal Benowitz, a professor at the University of California San Francisco. "But the practice of gradually reducing the nicotine content in cigarettes without any other incentives during the entire experiment did not achieve the expected effect."

The main ingredients of electronic cigarettes

There are three main components of e-cigarette smoke: nicotine, flavorings, and solvents such as glycerin.

Nicotine is the main ingredient in traditional tobacco and the main cause of addiction. Although e-cigarettes are advertised to have lower nicotine content than traditional cigarettes, they are not strictly regulated, and some e-cigarettes contain extremely high nicotine content, which may be much more harmful than ordinary cigarettes.

Although e-cigarettes do not contain tar, the nicotine in them is not harmless. Simply inhaling nicotine will also cause health risks. Nicotine itself is not a carcinogen, but it can act as a "tumor initiator". Moreover, there is sufficient evidence to show that exposure of fetuses and adolescents to nicotine will have long-term adverse consequences on brain development.

Flavoring. Compared with the smell of traditional cigarettes, electronic cigarettes with fruity, creamy, and minty flavors are more colorful, fragrant, and delicious, and the various flavorings play an important role.

The dangers of smoking electronic cigarettes

1. For those who suffer from gastrointestinal diseases, smoking can make them worse. For those who suffer from gastric ulcers or duodenal ulcers, the healing of the ulcers will be slowed down, and even develop into chronic diseases. Smoking can stimulate the nervous system, accelerate the secretion of saliva and gastric juice, and make the gastrointestinal tract tense, causing smokers to lose their appetite. In addition, nicotine can cause the blood vessels of the gastrointestinal mucosa to contract, which also causes loss of appetite.

2. Smoking can cause colon cancer. The chance of developing this cancer is proportional to the amount of tobacco smoked. Studies have shown that although stopping smoking can reduce the chances of other diseases such as heart disease and lung cancer, the risk of developing colon cancer is still very high.

3. While smoking harms the health of smokers themselves, secondhand smoke also affects non-smokers. In addition to irritating the eyes, nose and throat, it also significantly increases the chances of non-smokers developing lung cancer and heart disease. If children live with some smokers, their respiratory systems will be more susceptible to infection. Other effects include increased coughing, wheezing, sputum, damage to lung function and slow lung development.
