E-cigarettes produce a vapor from a solution containing a psychoactive chemical, most often nicotine or tetrahydrocannabinol (THC), as well as flavorings and other additives that users inhale. According to the Monitoring the Future study, e-cigarette usage has increased dramatically among teenagers since its debut in the early 2000s. Over 40% of high school seniors reported use in the previous year. Adolescents are particularly exposed to the dangers of e-cigarettes because they are targeted as new users with commercials and flavoring chemicals, and they are not using them to quit smoking. The pulmonary dangers of vaping are quickly becoming apparent, with the most concerning being the disease known as e-cigarette/vaping-associated lung injury (EVALI). Extrapulmonary effects, including cardiovascular, immunologic, and neurodevelopmental impacts, have also been documented in recent investigations. Many of these effects will almost certainly be dose-dependent. To reduce or eliminate new e-cigarette initiation, public health activities are urgently needed to help current e-cigarette users trying to quit. &nbsp;</span></span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:107%"><span style="font-family:Calibri,sans-serif"><b><span style="font-size:12.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times="">Conclusion:</span></span></span></b><span style="font-size:12.0pt"><span style="line-height:107%"><span new="" roman="" style="font-family:" times=""> While we were looking for cohort studies, such studies are not released yet but we firmly support the prohibition of e-cigarette flavorings and advertising focused on teenagers, and we urge doctors to be aware of the growing pandemic.</span></span></span><span lang="FA" dir="RTL" style="font-family:"Times New Roman",serif"></span></span></span></span><br> &nbsp; Vaping ,Cigarettes ,E-cigarettes 1 8 http://intjmi.com/browse.php?a_code=A-10-1-420&slc_lang=en&sid=1 Sheida Khosravaniardakani Sheida ‎ Khosravaniardakani 10031947532846004759 10031947532846004759 Yes Student Research Committee , Shiraz University Of Medical Sciences, Shiraz, Iran
