According to vapingpost, a public health care study of 1556 adolescents in South Korea found that many factors were associated with increased levels of e-cigarettes among adolescents, including increased weekly allowance, access to flavoring products and exposure to second-hand smoke.
In the study entitled "what factors affect adolescents' continuous use of e-cigarettes?" 55.1% of the participants reported that they had used e-cigarettes for 6-30 days in the past month, while 44.9% of the participants used e-cigarettes within 1-5 days.
The researchers found that among the main factors leading to teenagers' preference for e-cigarettes, they believed that e-cigarettes were not as harmful as cigarettes, could be easily hidden, were easy to buy, and offered a variety of flavors.
In addition, teenagers who have higher weekly allowance and are exposed to secondhand smoke at home are more likely to use e-cigarettes more often, the researchers said.
At the same time, a recent study of e-cigarette behavior among Canadian adolescents found that the proportion of adolescents aged 16 to 19 doubled between 2017 and 2019, and that higher nicotine levels in North America relative to Europe may be the culprit.
Within the European Union, the tobacco products directive (TPD), which came into effect in May 2017, prohibits the sale of electronic liquids containing more than 20 mg / ml nicotine. Public health experts have long argued that capping nicotine on safer alternatives, such as e-cigarettes, will have an adverse effect on the national smoking rate, forcing former smokers who have switched to smoking to smoke again.
However, on the other hand, the regulation may have a positive impact on the use rate of e-cigarettes among young people to ensure that they are not addicted to nicotine.
A survey of more than 12000 Canadians aged 16 to 19 between 2017 and 2019 found that the number of participants reporting last month's usage more than doubled, from 8.4% in 2017 to 17.8% in 2019.
