E-cigarettes; what you need to know

Targeted to people trying to give up smoking the e-cigarette is becoming increasingly popular. Although a relatively new addition to the ‘quitting’ market they are now visible practically everywhere, from bars and hotels to the beach and even trains!

But what do we actually know about e-cigarettes and, as parents, are we informed enough to have conversations with our children about them and potential risks. 

What is nicotine?

Nicotine is a toxic, colourless, oily liquid which is the chief component of tobacco. When inhaled as smoke the nicotine is absorbed through small air sacs in the lungs. It is highly addictive and can cause increased blood pressure and heart and lung problems.

What are e-cigarettes?

E-cigarettes are battery-powered devices that mimic the process of smoking by heating a nicotine liquid into a vapour as the user inhales.

How are they used?

Simulating a cigarette, a user inhales the vapour through a replaceable cartridge. Within the cartridge is a mixture of nicotine as well as artificial flavourings such as menthol and the chemical Propylene Glycol (PG). As this liquid is inhaled and exhaled as an odourless vapour, using an e-cigarette is often called ‘vaping’.

What is Propylene Glycol?

Propylene Glycol or PG is the main chemical found in e-cigarettes; it is a form of mineral oil and alcohol. PG comes in lots of different forms, and is found in everything from antifreeze to snack foods. At its highest concentration or industry grade it is used in paints, enamels and engine coolants, however when levels are far less concentrated it is used at a pharmaceutical grade and can be found in ointments, topical drug products and sometimes food products.

Why are people using e-cigarettes?

For many people trying to give up smoking it is the process of breaking the habit that is the hardest and as e-cigarettes replicate the process of smoking it addresses the physiological and behavioural aspects of smoking addiction. E-cigarettes also do not contain tobacco and the associated chemicals found within cigarettes including tar. As the user breathes vapour there is also a reduced risk of second hand smoking. In fact, recent studies have suggested that 80-84% of e-cigarette users thought they were less harmful than traditional cigarettes.

Do they work?

There is no evidence at the moment that proves the effectiveness of e-cigarettes in helping users quit. Research carried out in the UK , USA , Canada and Australia of 6000 current and former smokers found that e-cigarette users were far more likely to reduce their cigarette intake but no more likely to give up smoking. Similarly Dr Tarun Weeramanthri , Executive Director of Public Health at the Western Australia Department of Health, told ABC Radio that ‘when we look at the evidence, many more people keep smoking both normal cigarettes and e-cigarettes’.

Are they safe?

Nicotine in any form is highly addictive and as the vapour inhaled in an e-cigarette is not only water, the user still inhales a large number of toxins. As e-cigarettes are still relatively new to the market no long term studies have been carried out and therefore we do not know the long term risks of inhaling Propylene Glycol on a regular basis. In terms of e-cigarettes appealing to our children; e-cigarettes are marketed in such a manner that may attract young people, glamourous, cool, sleek as well as flavoured vapours, vanilla, banana split, and cola to mention three.

What now?

Although smoking rates in Australia are decreasing, and children are generally aware of the associated health risks, some will still be confronted with decisions about smoking. It is important to give our kids as much information as possible when it comes to smoking to empower them to make healthier and safer choices in the future. With regards to the e-cigarette, we hope that they will receive the same restrictions as tobacco products in order to reduce the risk of e-cigarettes appealing to children and young people.


What can I do?

Here are some other ideas you can do at home to discuss smoking with your family:

Download our ‘The Smoky Case’ app where you and your kids can explore the facts around smoking through the eyes of time travelling detective Mac McHardy and his sidekick ‘Conan’ to solve the case of why smoking is unhealthy.

Conversation starters you could try when using/after using the app:

  • Why would they choose not to smoke?
  • What advice would you give your friends about smoking?

Use incidental moments when children see cigarettes in use when you are out and about or on the television/movies to create a conversation about smoking:

  • Did you know that most teenagers don’t smoke?
  • What advice would you give your friends about smoking?
