E-cigarettes or electronic cigarettes are battery-operated devices in

E-cigarettes or electronic cigarettes are battery-operated devices in high-tech designs that give scented vapors of nicotine for the user to inhale. Since these devices vaporize a liquid containing nicotine, and since the produced vapor is inhaled or "vaped", the user gets a sensation similar to that of smoking regular cigarettes but without the smoke, the smell, or the cancer-causing tar produced by burning tobacco. According to manufacturers of e-cigarettes, these devices are intended only for adults who want to give up smoking.

Readily available across the counter, sleek enough to sneak into the school, and devoid of the telltale smoke and smell, vaping devices are being rampantly used by students in spite of all efforts by parents and teachers alike to stop their usage, however. Moreover, as the popularity and ease of availability of e-cigarettes rose, "vaping" turned into the most popular form of nicotine consumption among teenagers in U.S. high and middle schools: e-cigarette use increased by 900 percent among these students from 2011 to 2015. Disciplinary actions such as detention and expulsion have been unable to make the teenagers give up e cigarettes. Moreover, a majority of them were nonsmokers before taking to the device. Students argue that vaping is merely a habit and not an addiction. They agree that there are chemicals in vaping but less than those in cigarettes. School authorities, on the other hand, believe that e-cigarettes are creating a whole new generation of nicotine addicts.

School officials rue the fact that students are misguided in equating safer with safe: The manufacturers’ claim that e-cigarettes are safer than cigarettes does not mean the devices are safe in general, they say. Additionally, there are several reasons to doubt the "safer" claim too. Firstly, e-cigarettes contain additives that may seem harmless at the outset but form cancer-causing compounds when heated. Secondly, a higher concentration of nicotine in the vaping pods than found in regular cigarettes makes e-cigarettes much more addictive than the regular ones. Thirdly, studies indicate that vaping caused more teenagers to try out cigarettes. Finally, there isn't enough research to fully understand the potential long-term risks to health. The risks of cigarettes are well documented, but e cigarettes are too new for the researchers to comprehend their ill-effects, turning today's youth into a "guinea pig generation".
