When electronic cigarettes with colorful packaging and fruit flavors appear among teenagers, many people mistakenly believe that they are harmless "fashionable toys". But the truth is, electronic cigarettes are by no means a safe substitute for cigarettes, and they are posing a hidden threat to the health of young people. Visible packaging, invisible health "killers". There are various health "killers" hidden in the smoke of electronic cigarettes. Teenagers' bodies are still in the developmental stage, and their respiratory systems are particularly fragile. Smoking electronic cigarettes may cause acute lung damage, such as acute eosinophilic pneumonia, diffuse alveolar hemorrhage, allergic pneumonia, and even trigger severe asthma. Long term use of electronic cigarettes can quietly increase the risk of major diseases such as heart attacks. What is even more worrying is that research evidence shows that electronic cigarettes not only threaten lung health, but also increase the risk of cardiovascular disease, even affecting fetuses. The second-hand smoke generated by electronic cigarettes, which can cause harm to multiple people when used by one person, should not be underestimated. It will increase the concentration of carcinogens in the air, and as the heating temperature of electronic cigarettes increases, the release of carcinogens may double. This means that when teenagers use electronic cigarettes, their classmates and friends around them will also be forced to inhale these harmful fumes, and their health will be affected. Under the banner of "quitting smoking", the World Health Organization has explicitly stated that electronic cigarettes are not recommended as a smoking cessation tool. Many people who use e-cigarettes with the intention of quitting smoking not only fail to get rid of tobacco, but also use both e-cigarettes and cigarettes at the same time, resulting in a combination of health hazards. For teenagers who have never smoked before, electronic cigarettes are a "dangerous trap" - the nicotine contained in the vast majority of electronic cigarettes is extremely addictive. Once teenagers try e-cigarettes, their likelihood of starting to use cigarettes will at least double, leading them into a vicious cycle of addiction. Behind the temptation of electronic cigarettes is a serious threat to the health of teenagers. Whether for their own physical health or to protect the safety of those around them, teenagers should stay away from electronic cigarettes. At the same time, we also call on parents and schools to strengthen guidance and jointly create a healthy and smoke-free growth environment for young people. (New Society)
