Since its inception in 2018, Singapore’s ban on vapes has sparked debates regarding its efficacy and whether further measures are needed to discourage youth vaping.

On May 8, the Health Sciences Authority announced a review of penalties aimed at addressing the advertising, importation, and distribution of vapes. Efforts to promote “pro-health” content, including a vape-free campaign targeted at youths, were also emphasized.

Singapore is among 39 countries worldwide that have implemented vape bans, contrasting with 82 nations regulating the sale and distribution of e-cigarettes.

In discussions surrounding Singapore’s vaping ban, some have questioned its prudence. Countries like New Zealand and the United Kingdom assert that vaping poses fewer risks than smoking and can aid in smoking cessation.

Here are toxicological insights addressing pertinent questions:

Known Hazardous Substances in Vapes

E-cigarettes, like conventional cigarettes, contain thousands of chemicals. Notable hazardous substances include heavy metals, polyaromatic hydrocarbons, and fine particulate matter.

Exposure to Harmful Chemicals When Vaping

Toxicology principles dictate that the dose makes the poison. While vapes contain similar harmful chemicals as cigarettes, the exposure varies based on factors like brand and frequency of use.

Additional Health Risks of Vapes

Vapes may contain other toxic chemicals absent in conventional cigarettes. Propylene glycol, used in e-cigarettes, poses uncertain risks when inhaled. Heating elements in vapes can produce formaldehyde, damaging respiratory cells. Flavoring agents like diacetyl may lead to severe lung conditions.

Risk of Addiction with Vaping

Nicotine, present in e-cigarettes, can induce addiction, particularly in developing brains. Besides nicotine, vapes may contain other psychoactive components, increasing health risks.

Public policy on vaping controls necessitates scrutiny from the government, businesses, and the public. Individual responsibility complements public policy efforts, emphasizing informed decision-making.

Understanding the scientific basis behind vaping risks can guide responsible choices, fostering a balanced approach to public policy and personal actions.
