An Electronic Cigarettes is a battery-powered vaporizer which provides a flavor and feel similar to tobacco smoking, but there are differences. A noticeable difference between the traditional cigarette and the e-cigarette is sense of touch. The user inhales an aerosol, commonly called vapor, rather than cigarette smoke. Once the user inhales, the airflow passes through a pressure sensor which activates the heating element that atomizes the liquid solution inside the cartridge into vapor. Other e-cigarettes have a push-button switch to turn on the device manually.
The main reasons young people experimented with e-cigarettes were due to curiosity, flavors, and peer influences. E-cigarettes can appeal to youth because of their high-tech design, assortment of flavors, and accessibility online. Candy and fruit flavors e-cigarettes are designed to appeal to young people. E-cigarettes could be more appealing to non-smoking youths than traditional cigarettes, and some have been shown to appeal to girls as young as 11. In the US, North West of England and Paris, vaping by children may be due to experimentation. Infants and toddlers could ingest the e-liquid from an e-cigarette device out of curiosity.
Users may begin by using a disposable e-cigarette, and it has been shown that e-cigarette users often start with E- Cigarette resembling normal cigarette, eventually moving to a later-generation device. Most later-generation e-cigarettes shifted to get a “more satisfying hit”, and users may adjust their devices to provide more vapor for better “throat hits”.
Vaping may have potential in harm reduction compared to smoking. When used to quit smoking, they could reduce harm even more if the tobacco user quits but Electronic Cigarettes are not harmless because nicotine has long-term adverse effects, may contain impurities, and nicotine is addictive, which may have serious side effects, particularly if users use unconventional ways to increase the doses of nicotine exposure. A 2012 review found electronic systems deliver less nicotine than smoking, raising the question of whether they can effectively substitute for tobacco smoking over a long-term period. A 2012 review found e-cigarettes could considerably reduce traditional cigarettes use and they likely could be used as a lower risk replacement for traditional cigarettes, but there is not enough data on their safety and efficacy to draw definite conclusions. E-cigarette use for risk reduction in high-risk groups such as people with mental disorders is unavailable.
The risks of Electronic Cigarette use are uncertain. There is little data about their health effects, and considerable variability between vaporizers and the contents of the aerosol delivered to the user. The limited evidence suggests that vaping is probably safer than smoking. One review found, from limited data, their safety risk is similar to that of smokeless tobacco, which has about 1% of the mortality risk of traditional cigarettes. Another concluded that regulated FDA products such as nicotine inhalers are probably safer than e-cigarettes.
