The rise of e-cigarettes is largely due to its innovation in traditional smoking methods. It abandons the traditional way of burning cigarettes and adopts high-tech atomization technology to convert smoke liquid into aerosols for inhalation. The benefits of this change are multifaceted. First of all, from an environmental perspective, the smoke produced by the burning of traditional cigarettes will permeate the air, not only affecting others, but also causing indoor and outdoor air pollution. The aerosols produced by disposable e-cigarettes are relatively clean and will not pollute the air as long as traditional cigarette smoke, and have less impact on the surrounding environment. From the perspective of personal hygiene, e-cigarettes do not have the ashes and butts left by traditional cigarettes after burning, which avoids the pollution of these garbage to the environment and makes the living environment of smokers cleaner. For those who need to quit smoking, e-cigarettes can also play a certain auxiliary role. The nicotine component it contains can help smokers gradually reduce their dependence on nicotine and achieve the goal of quitting smoking. By controlling the nicotine content in e-cigarettes, gradually decreasing from high to low, the body can slowly adapt and reduce the withdrawal reaction during the process of quitting smoking. Moreover, it can meet the habitual movements and psychological needs of smokers, provide a similar experience when they want to smoke, and help them gradually get rid of their dependence on traditional cigarettes. However, we cannot ignore the negative effects that e-cigarettes may bring. In addition to the addictiveness and potential health risks of nicotine, the use of e-cigarettes may also cause some other problems. Some users reported that after long-term use of e-cigarettes, they will experience symptoms such as dry mouth and throat discomfort, which may be related to the stimulation of certain ingredients in e-cigarette liquid on the oral and throat mucosa. Because the use of e-cigarettes is relatively hidden, it is easy for teenagers to come into contact with it, thereby increasing their risk of trying to smoke. Once teenagers become dependent on nicotine, it will not only affect their physical health, but may also have a serious impact on their study and life. E-cigarettes are a double-edged sword. It not only provides smokers with a relatively healthy and convenient smoking option, which helps to quit smoking to a certain extent; but there are also some health risks and social problems that cannot be ignored. We need to look at it objectively and comprehensively, give full play to its positive role, and at the same time reduce its negative impact by strengthening supervision and improving consumer awareness. Only in this way can e-cigarettes find a balance between health and convenience and bring a truly beneficial experience to consumers.
