Vaping Inside MRT Train: Man Fined $2,200 After Viral Video

A 37-year-old man received a $2,200 fine after a video showing him vaping inside MRT train went viral on TikTok. The incident, which occurred in early 2025, sparked widespread discussion about Singapore’s strict anti vaping in Singapore laws and how video evidence supports law enforcement.

The case of Tay Choon Loong Aloysius demonstrates both the consequences of vaping inside MRT train carriages and how surveillance footage—whether from official CCTV systems or citizen recordings—enables authorities to identify and prosecute offenders.

The Viral Video That Started Everything

In April 2025, a video began circulating on TikTok showing a man vaping inside MRT train before quickly attempting to hide the device. The footage captured clear images of the offender inhaling from the vaping device in the enclosed train carriage, surrounded by other commuters.

According to The Straits Times coverage of the incident, the video quickly gained traction on social media, drawing attention from both the public and authorities. Comments on the video expressed concern about secondhand vapor exposure in enclosed public spaces and questioned whether the person would face consequences.

The viral nature of the recording meant the offender couldn’t escape identification. Within days, authorities had identified the man caught vaping inside MRT train as Tay Choon Loong Aloysius, a 37-year-old Singapore resident.

Health Sciences Authority Investigation Into Vaping Inside MRT Train

On April 22, 2025, officers from the Health Sciences Authority (HSA) conducted a raid at Tay’s residence. The HSA enforces Singapore’s tobacco and vaping regulations, treating vaping devices as prohibited “imitation tobacco products” under Singapore law.

According to Mothership’s report on the case, the search of Tay’s home did not uncover any prohibited items. However, Tay admitted to being the person shown vaping inside MRT train in the viral video. He informed investigators that he had already disposed of the vaping device before the raid.

The investigation revealed that Tay had purchased the vape for $22 from a seller in the back alley of a coffee shop in Geylang. Between February and March 2025, he had purchased three vaping devices on separate occasions from the same location from a Bangladeshi individual.

This case highlights how vaping in Singapore is illegal at every stage—possession, purchase, and use all carry separate legal consequences.

Why He Did It: The Offender’s Explanation

During the investigation into vaping inside MRT train, Tay explained his reasons for using the vaping device. He told authorities he vaped to stay awake and alert during his morning commute to work. The device served as an alternative after he had quit smoking cigarettes.

MustShareNews reported that Tay believed vaping was a safer alternative to smoking—a common misconception that Singapore’s strict regulations specifically address. The country’s anti vaping in Singapore stance stems from concerns that vaping products are unregulated, meaning users cannot verify what substances they inhale.

His explanation reflects a broader pattern among vaping inside MRT train offenders who view e-cigarettes as smoking cessation aids without understanding Singapore’s complete prohibition.

Court Outcome: $2,200 Fine for Vaping Inside MRT Train

On February 24, 2026, Tay appeared in court and pleaded guilty to two charges: one count of possessing an imitation tobacco product and one count of purchasing it. The court sentenced him to pay $2,200 in fines.

According to STOMP’s coverage, the judge emphasized several important points during sentencing:

Public Safety Concern: Vaping inside MRT train carriages affects other commuters, including students and children who share enclosed spaces during their daily commutes.

Unregulated Products: Vaping devices are banned and unregulated in Singapore, meaning users cannot know what substances they inhale. This uncertainty creates health risks for both users and those exposed to secondhand vapor.

Deterrence Message: The punishment for vaping in Singapore serves as a deterrent, warning others that violations will result in prosecution regardless of the offender’s intentions.

Global Nation’s report noted that this vaping inside MRT train case received significant attention due to the viral video, making it a high-profile example of Singapore’s enforcement approach.

Why Vaping in Singapore is Illegal

Singapore maintains one of the world’s strictest anti vaping in Singapore policies. Unlike many countries where vaping occupies a legal gray area or faces partial restrictions, vaping in Singapore is illegal completely.

The prohibition covers:

Possession: Owning any vaping device, e-cigarette, or related components is illegal. This includes devices, cartridges, refill liquids, and accessories.

Purchase: Buying vaping products—whether in Singapore or importing from overseas—violates Singapore law. Even purchasing online from foreign websites for delivery to Singapore addresses is prohibited.

Use: Using vaping devices anywhere in Singapore, including private residences, carries legal consequences if discovered. Vaping inside MRT train carriages or other public transport faces additional scrutiny due to enclosed spaces.

Sale: Selling, distributing, or offering vaping products is a serious offense with substantial penalties.

The Health Sciences Authority classifies vaping products as “imitation tobacco products” under the Tobacco (Control of Advertisements and Sale) Act. This classification subjects vaping to the same regulatory framework as prohibited tobacco products.

Singapore’s position differs from countries that regulate vaping as a harm reduction alternative to smoking. Singapore authorities argue that insufficient evidence supports vaping as a safe cessation method, while concerns about youth uptake and unknown health effects justify complete prohibition.

Understanding how CCTV surveillance works helps explain how authorities monitor public spaces and gather evidence supporting enforcement of these regulations.

Punishment for Vaping in Singapore

The punishment for vaping in Singapore varies based on the specific offense and circumstances:

First-Time Possession: Fines up to $2,000 for possessing vaping devices or components.

First-Time Purchase: Fines up to $500 for purchasing vaping products.

Repeat Offenses: Higher fines and potential imprisonment for subsequent violations.

Sale or Distribution: Significantly higher penalties including substantial fines and imprisonment.

In Tay’s case, the combined $2,200 fine reflected charges for both possession and purchase—demonstrating how multiple violations compound penalties.

The court’s emphasis on public concern about vaping inside MRT train carriages suggests that location aggravates offenses. Vaping in enclosed public spaces where others face involuntary exposure may draw stricter judicial attention than private use discovered through other means.

Video surveillance monitoring plays a role in documenting such violations, whether through official CCTV systems in public transport or citizen recordings that go viral.

Vaping in Singapore Airport: What Travelers Must Know

International travelers frequently ask about vaping in Singapore airport regulations. The rules are straightforward: bringing vaping devices into Singapore is prohibited regardless of entry point.

Arrival Restrictions: Customs officials at Changi Airport actively screen for vaping devices. Travelers carrying e-cigarettes, vape pens, or related products face confiscation and potential prosecution.

Transit Passengers: Even passengers transiting through Singapore without formally entering the country should exercise caution. Vaping in airport facilities violates regulations.

Departure: Travelers departing Singapore cannot purchase vaping products for their journey, as no legal sales exist within the country.

Singapore’s comprehensive surveillance capabilities extend throughout Changi Airport and other entry points, supporting customs enforcement efforts.

What If You Accidentally Bring a Vape to Singapore?

Travelers who accidentally bring vaping devices to Singapore face a difficult situation. The best approach involves:

Declare Immediately: Contact customs officials before passing through immigration. Voluntary declaration may result in more lenient treatment than discovery during baggage screening.

Surrender the Device: Be prepared to forfeit any vaping products. Confiscation is certain; prosecution is discretionary based on circumstances.

Cooperate Fully: Honest explanation of accidental possession works better than attempted concealment. Authorities distinguish between deliberate smuggling and genuine mistakes.

Seek Guidance: For valuable devices, some travelers have shipped items back to origin countries before entering Singapore, though this requires advance planning.

Understanding that vaping in Singapore is illegal helps travelers avoid accidental violations through proper preparation before departure.

How Video Surveillance Supports Law Enforcement

This vaping inside MRT train case demonstrates the power of video evidence in law enforcement. The viral TikTok video provided authorities with clear identification of the offender, enabling investigation and prosecution that might otherwise prove impossible.

Several aspects of this case highlight surveillance effectiveness:

Visual Identification: The video captured clear images enabling positive identification despite the offender’s attempt to hide the device.

Documentation Quality: Even smartphone footage provided sufficient evidence for prosecution, demonstrating how reliable CCTV evidence supports legal proceedings.

Deterrence Effect: The viral nature of the video and subsequent prosecution sends a clear message to potential offenders that violations may be recorded and prosecuted.

Public Space Monitoring: MRT systems utilize extensive 24/7 CCTV monitoring throughout stations and carriages, supplementing citizen recordings with official surveillance.

Property managers and business owners can learn from this case about the benefits of video surveillance in enforcing regulations and maintaining safe environments. Professional monitoring services provide higher-quality evidence than incidental smartphone recordings while enabling real-time security monitoring that can prevent incidents before they escalate.

Public Reaction and Broader Implications

The vaping inside MRT train case generated significant public discussion about Singapore’s strict regulatory approach. Comments on social media platforms reflected mixed reactions:

Supportive Views: Many commuters expressed relief that authorities enforce anti vaping in Singapore regulations actively. Parents particularly appreciated protection of children from secondhand vapor exposure in enclosed public spaces.

Questions About Proportionality: Some commenters questioned whether $2,200 fines appropriately match the offense severity, though most acknowledged Singapore’s consistent approach to regulatory enforcement.

Awareness Impact: The viral vaping inside MRT train incident raised awareness about Singapore’s vaping prohibition, potentially preventing future violations by those previously unaware of the law’s scope.

The case joins other real examples of surveillance supporting law enforcement, demonstrating how video documentation enables prosecution of offenses that might otherwise go unpunished.
