액상형 전자담배 사용자의 가향제품 여부에 따른 무니코틴 및 니코틴 농도별 액상사용 양상

Abstract

Background: A wide range of nicotine concentrations for e-liquids for electronic cigarettes are available. However, in South Korea, there is a remarkably lack of comprehensive data on their utilization. This study focuses on understanding the experiences of e-liquid consumers, particularly regarding varying nicotine concentrations and flavoring. Methods: An online survey conducted in May and June 2022 included participants aged 19-39 years who consented to participate in the study. Administered by a research company, the survey collected data on age-specific e-cigarette usage patterns, perceptions, and health-related factors. E-liquid usage patterns were subjected to descriptive analysis, and chi-square tests were employed to compare various categories. Results: Among the 6,374 ever smokers, a total of 4,479 (70.3%) had used liquid e-cigarettes. Moreover, 3,334 participants had experience with nicotine-free liquids, including 2,637 flavored product users. Notably, 2,063 respondents preferred nicotine-free e-liquids, whereas 1,991 chose low-nicotine products or smoking cessation aids. Adolescents and young adults often classified their e-liquid as “unknown.” Low-nicotine products were prevalent across all age groups (13-18 years: 21.7%, 19-24 years: 33.7%, and 25-39 years: 42.3%). Combinations of PG (Propylene Glycol), VG (Vegetable Glycerin) were frequently used (across age groups: 24.6%, 30.6%, and 42.5%, respectively). Synthetic nicotine use was reported at 11.9%, 18.8%, and 25.3%, respectively, and 619 of 1,722 respondents were high-nicotine concentration users. Conclusion: Many users lacked knowledge about the ingredients used in their vaping products, highlighting the need for improved awareness. Continuous research is needed to collect information on these products and develop proper action to prevent hazardous health effects from various liquid vaping products.
