Learn more about the common mistruths of vaping.

You may have heard of them before, but did you know that they are false?

False!

The World Health Organisation (WHO) has declared that vapes are harmful to health and not safer than regular cigarettes.

Studies show that vaping generates toxic substances, some of which are known to cause cancer and increase the risk of heart and lung disorders. For example, Vitamin E acetate found in some vapes is strongly linked to lung injury, such as pneumothorax (collapsed lungs).

Nicotine in e-cigarettes can also impact brain development in young people, affecting their ability to manage attention and learning, mood and impulse control1. It can also adversely affect the development of the foetus in pregnant women2.

Based on vapes seized by HSA in Singapore, the nicotine consumed from 1 vape pod is equivalent to about 3 to 4 cigarette packs. With vape manufacturers putting more nicotine into vapes over the years, these risks as well as that of nicotine addiction are greatly increased3.

Emissions can also pose risks to bystanders. Bystanders may experience irritation of the respiratory tract as a result of exposure to fine particulate matter, like propylene glycol and glycerol4.

Don't believe that!

Ingredients in vape e-liquids may vary widely between different manufacturers, and can contain harmful, toxic chemicals.

Some commonly found ingredients5 include:

Nicotine

  • found in pesticides
  • can cause harmful side effects, which include decreased appetite, increased heart rate and blood pressure, sweating, nausea, and even diarrhoea in extreme cases
  • can impact brain development in youth, affecting their ability to manage attention and learning, mood and impulse control1

Benzene

  • found in car exhaust fumes, fuels and detergents
  • can cause infertility and leukaemia with long-term exposure

Formaldehyde

  • used as an embalming fluid and in adhesives for wood
  • known to cause cancer and infertility

Diacetyl

  • a food flavouring agent
  • can cause permanent lung scarring and inflammation when inhaled

Toluene

  • found in paints, lacquers and nail polishes
  • can cause cancer and infertility

Metals

  • found in batteries
  • can lead to respiratory diseases when inhaled

As e-liquids come in a concentrated form, you can accidently expose yourself to potentially toxic levels of nicotine and other harmful substances6 from simply refilling the e-cartridges.

Untrue!

Vaping devices heat e-liquids or nicotine salts into vapours that are inhaled7.

Some chemicals in e-liquids such as propylene glycol, vegetable glycerine, and flavourings are meant to be eaten but not inhaled8. Other commonly found ingredients in vape-liquid include nicotine, benzene, formaldehyde, diacetyl, toulene, metals and more. Some of these components can turn into other potentially dangerous chemicals when heated in vaping devices.

Vaping thus exposes the lungs to a variety of chemicals that can cause serious lung injuries9.

Don't be fooled!

In youths, nicotine impacts brain development, permanently lowering the developing brain’s impulse control, affecting its ability to manage attention and learning1. It can also lead to mood disorders10.

Problems with impulse control (i.e. failure to resist urges) can result in sudden physical or verbal outbursts, an internet addiction, or even compulsive eating.

Medical literature also suggests that vaping can be a gateway to smoking and other drug abuse, particularly among youth and young adults11, with growing evidence that those who vape have 3 times the risk of becoming smokers as compared to those who don’t12, 13, 14, 15. This can result in even more negative impacts on health that are hard to recover from.

Think again!

What you see or have been advertised may not be what you get. There have been reports and studies showing that some products labeled as nicotine-free do, in fact, contain nicotine16, 17. This could be due to contamination, mislabeling, or even intentional deception by manufacturers.

That's not true!

Vapes contain toxic substances like fine particulate matter that are harmful to not only vapers themselves but others in the same indoor space as well18.

Bystanders may experience irritation of the respiratory tract as a result of exposure to subtances like propylene glycol and glycerol found in fine particulate matter4.

Breathing in particulate matter can result in increased risks of developing heart, lung, and other harmful diseases, worsening of existing illnesses, and shortened life expectancy19.

It is not a scare tactic - vaping can cause lung injuries.

Vaping can trigger an inflammation that causes small blood vessels in the lungs to close up, leading to impaired gas exchange and potential respiratory complications20.

Vitamin E acetate (found in some e-liquids) is strongly linked to an outbreak of lung injuries in the United States, leading to hospitalisations and deaths21. In Singapore, two vapers had to undergo operations to treat their collapsed lungs (pneumothorax)22.

Even when no nicotine is involved, inhaling the mist from vapes can damage the lungs due to chemicals present in e-liquids.

That's an inaccurate claim.

Studies show that smokers who used vapes to help them quit cigarettes were less likely to successfully quit as compared to other quit attempters (pharmaceutical aid or no product).

Statistics show that nearly 60% of recent quitters who were daily vape users relapsed and resumed cigarette smoking within 2 years 23.

Smokers using vapes as a cessation tool may also end up both vaping and smoking24, which is more harmful than using vapes or cigarettes individually.

Time for a reality check.

Vapes contains nicotine, which can lead to addiction.

Based on vapes seized by HSA in Singapore, the nicotine consumed from one vape pod is equivalent to about 3 to 4 cigarette packs. In addition to that, vape manufacturers have been putting more nicotine into vapes over the years, which greatly increases the risk of nicotine addiction3.

Vapes being marketed as nicotine-free have been found to contain nicotine as well, and users may be addicted without knowing.

Are you sure?

Vapes contain the highly addictive chemical nicotine. When inhaled, nicotine is absorbed within 20 seconds into the bloodstream and releases a feel-good chemical called dopamine in the brain. This dopamine "rush" is a big part of the addictive process.

When the person stops vaping, the level of nicotine in the person’s brain decreases, leading to increased cravings for nicotine. This can result in nicotine dependence. Attempting to quit may cause them to experience withdrawal symptoms, potentially leading the person to resume vaping or smoking25. Hence, quitting vaping is challenging due to its highly addictive nature.

Mistruths About The Law

Here are the FACTS.

Harmful and imitation tobacco products are banned to protect Singapore's population from the dangers of vapes and additional tobacco use.

About 1 in 11 Singaporeans are addicted to tobacco products (e.g. cigarettes)26, and will need time and support to quit. As such, banning cigarettes, given the existing pool of smokers, will increase the flow of smuggled cigarettes into Singapore and result in black markets for cigarettes.

The vaping ban prevents this from occurring with new tobacco products and driving up the overall use of tobacco in our population.

Additionally, vapes are harmful27 as they:

  • contain nicotine that can harm the developing brains of youths, affecting their ability to manage attention and learning, mood and impulse control1.

  • contain cancer-causing chemicals and other toxic substances such as metal nanoparticles and particulate matter (PM2.5) that increase the risk of heart and lung diseases

  • are associated with lung injuries

  • contain toxic substances (found in the heated aerosol produced by the device) that can harm users and others through second-hand exposure

  • can be a gateway for non-smokers, particularly youths, to start using cigarettes

That's NOT what the law states.

Vaping is illegal in Singapore regardless of whether you vape in private or in public, and you will be subjected to penalties.

The ban on harmful and imitation tobacco products prohibits the use, import, distribution, sale, or offer for sale of:

  • harmful tobacco products (e.g. Shisha tobacco, smokeless tobacco, dissolvable tobacco, nicotine/tobacco candies and liquids, oral snuff, nasal snuff and so on)

  • imitation tobacco products (e.g. vaporisers such as electronic cigarettes, electronic pipes, electronic cigars and the like28)

Anyone caught owning, using and/or buying e-cigarettes, is liable to a fine not exceeding $2,000.

28 Berry, K. M., Reynolds, L. M., Collins, J. M., Siegel, M. B., Fetterman, J. L., Hamburg, N. M., Bhatnagar, A., Benjamin, E. J., & Stokes, A. (2018).

Tobacco Control, tobaccocontrol-2017-054108. https://pubmed.ncbi.nlm.nih.gov/29574448/

Incorrect!

When you buy and make payment for a vape, it is considered a purchase29, which is also prohibited.

The penalty for possessing, using or purchasing vapes is a fine not exceeding $2,000.

29 Singapore Statutes Online. (1993). Tobacco (Control of Advertisements and Sale) Act 1993. https://sso.agc.gov.sg/Act/TCASA1993

That's a costly assumption.

When you buy a vape on behalf of a friend and receive payment for the vape from him/her, it is considered a sale30.

The penalties for selling e-cigarettes are:

1st Offence:

  • Fine not exceeding $10,000

  • Imprisonment for a term not exceeding 6 months; or

  • Both fine and imprisonment

2nd & subsequent Offences:

  • Fine not exceeding $20,000

  • Imprisonment for a term not exceeding 12 months; or

  • Both fine and imprisonment
