Asia’s Teen Vaping Surge: Unmasking Risks and Mobilizing Solutions

Dear Editor,

The prevalence of e-cigarettes, frequently marketed with appealing flavors and featuring rechargeable and extensively customizable options, has significantly contributed to their popularity, raising urgent concerns for public safety. Initially marketed as aids for smoking cessation, e-cigarettes have paradoxically fostered a new nicotine addiction among youth. The rising popularity of vaping in Asia has shown an alarming trend. In Thailand, there has been a sharp increase in e-cigarette use among school-aged children (13-15 years), with rates increasing from 3.3% in 2015 to 17.6% in 2022. ¹ In Pakistan, approximately 8 million or 5% of the youth currently use electronic nicotine delivery systems (ENDSs). ² Malaysia has also seen a notable rise in e-cigarette usage; among teenagers aged 13 to 17 years, the rate increased from 9.8% in 2017 to 14.9% in 2022. ³ Similarly, the Philippines reported approximately 1.6 million vape users as of 2021, accounting for about 2.1% of the population. ⁴

The consequences of vaping in teenagers are numerous and severe. Various studies continuously demonstrate a strong association between vaping during teenage years and eventual tobacco use, hence substantially increasing the likelihood of developing nicotine addiction. ² Teenagers who vaped had a four times increased probability of starting to smoke, while the likelihood of quitting smoking decreased significantly among individuals in this age group. ⁵ E-cigarette consumption has notably escalated among both active and former smokers, who demonstrate a higher propensity for such devices than individuals who have never smoked. This pattern indicates a shift toward dual usage of both cigarettes and e-cigarettes, a behavior that may subject users to increased health risks. ²

The long-term health implications of e-cigarettes are currently uncertain; nevertheless, recent studies increasingly highlight the serious health risks associated with their use.

A study by Herzog et al ⁶ found that both vaping and traditional cigarette smoking induce similar DNA methylation changes linked to carcinogenesis. E-cigarette use is associated with several health risks, including cardiovascular problems such as tachycardia and increased blood pressure. ⁷ It was also found to be independently associated with an increased risk of incident heart failure. ⁸ In addition, vaping can lead to pulmonary issues such as chronic obstructive pulmonary disease (COPD) and bronchiolitis obliterans and contains harmful substances like nicotine and metals that can cause oxidative stress and inflammation. ⁷ Vaping during pregnancy can also lead to fetal development issues, and the use of these products has been linked to a severe lung condition known as EVALI, which has caused numerous hospitalizations and deaths. ⁷ E-cigarette aerosols contain numerous toxic chemicals, exposing users to dangerous substances like acetaldehyde, formaldehyde, and acrolein when inhaled. ²

These observations highlight the critical need for comprehensive action to stem the rising tide of teen vaping in Asian countries. A study in Hong Kong stated that adolescents’ use of e-cigarettes was linked to a lack of awareness about their harmful effects, potentially stemming from insufficient formal education on the topic in schools. ⁹ Stricter laws on the sale and promotion of e-cigarettes, along with intensive educational programs in schools and communities, can play an important role in preventing teenagers from developing this potentially dangerous habit. ²

In response to the increasing prevalence and the associated health risks, several Asian countries have implemented stringent regulations against e-cigarettes. Brunei, Cambodia, India, Laos, Qatar, Singapore, and Thailand have all completely outlawed the import, sale, and possession of these products. ¹⁰ This ban in India came into effect after the sales of e-cigarettes and vaping products nearly doubled from 1.6 to 3.3 million between 2014 and 2019. ² Countries that have not imposed outright bans on e-cigarettes are still taking significant measures to reduce vaping among the population. For instance, the Philippines and Taiwan have imposed strict regulations, including licensing for retailers, bans on public use, and mandatory health warnings on packaging. ¹⁰ Oman and Saudi Arabia are among the 22 countries enforcing plain packaging to curb the appeal of vaping products, demonstrating a commitment to tobacco control. ¹⁰ Similarly, South Korea has opted to impose heavy taxes on e-cigarettes as a deterrent. ¹⁰

Such measures set a precedent that other countries in the Asian region are encouraged to emulate in addressing this issue.

However, despite the legal framework in place, several challenges have undermined the effectiveness of these laws. The complete bans in countries like Singapore and Thailand have led to an escalating illegal trade, complicating enforcement efforts. ¹⁰ In countries like India, there is still a widespread public misunderstanding regarding the relative harms of e-cigarettes compared with traditional cigarettes, which has led to their continued use. ¹⁰ In addition, some low-income Asian countries such as Cambodia encounter logistical and resource limitations that make it difficult for them to enforce these bans. ¹⁰

To address these challenges, it is imperative for health care experts, educators, and parents to work together to raise awareness about the dangers of vaping. ² Teenagers who are already dependent on nicotine should have access to early intervention programs, counseling services, and support networks. ² Through the implementation of these techniques and the spreading of knowledge on the real hazards associated with vaping, society may safeguard its younger population from the detrimental consequences of this growing issue.
