Also current use increased since 2015 from 2.4 to 4.8%. In Great Britain, during 2020 16.4% of 11–18-year-old students had tried (at least once) e-cigs, compared to 15.4% in 2019 and to 12.7% in 2015.
Since the introduction of pod-based devices, vaping prevalence has tremendously increased, reaching 28% in 2019 and even 40.5% among 12th graders. In 2018, the National Youth Tobacco Survey reported that 20.8% of high school students and 4.9% of middle school students currently used e-cigarettes. Their social acceptance, together with their widespread availability, contributed to drastically increase primary use by adolescents and second-hand exposure in children, outlining the need for an assessment of their health effects in these categories. In contrast with a consistent decline in smoking prevalence among youth, over the past few years electronic cigarettes have rapidly gained popularity to the point of becoming the most common tobacco product in this age group. However, only in 2007 they became commercially available in USA and Europe.
Taking shape as a smoking cessation strategy or – in actual fact – as a legal alternative where conventional smoking was prohibited, e-cigarettes, invented by Hon Lik (a Chinese pharmacist), were patented in 2003. Liquid composition can include nicotine, a solvent and an utmost variety of flavorants. Įlectronic cigarettes (also known as E-cigs, Electronic Nicotine Delivery Systems-ENDS, vaping device or e-vaporizers) are an electronic device that can vary in size and shape, consisting of a battery, an electrical heater and a liquid, which is aerosolized to be inhaled. Over the last decade, reducing cigarette consumption has become a Public Health goal, therefore prevention campaigns intensified and restrictions on their marketing and access escalated. Tobacco smoke undoubtedly remains world’s leading cause of preventable disease.
