I stopped for petrol on my way to work last week. As I was at the counter paying, I managed to look away from the Giant Freddo and Kinder Surprise collection to see e-cigarettes. Flavoured, coloured, very cute looking e-cigarettes. It got me to thinking, are these toy-like cigarettes any better than the cigarettes, tucked away behind the clerk with all their health warnings?
E-cigarettes have been a hot topic for a while. And there seems to be quite a bit of confusion as to the health risks associated with them, even amongst us health professionals! So here’s the deal with these guys:
- E-cigarettes are also called electronic nicotine delivery systems (ENDS) and create a vapor of nicotine or other chemicals (propolyne glycol, water, flavours) – not always in a safe form – the FDA in the USA has had to warn companies against including even more harmful solutions
- They have been around since 1965 but first entered the market in 2003!
- The vapor does not contain smoke, tar or carbon monoxide (all present in conventional smokes)
- Some smokers use e-cigarettes as part of a ‘quit smoking’ strategy and this might really help some people quit
- As they contain nicotine, they are still as addictive as a packet of Malboro lights
- Ions such as nickel, tin, iron and chromium can be vapourised from the heating of the liquid – these can be dangerous to inhale
- It’s a little soon to know the exact health effects, but from some scientific studies, we probably know that e-cigarettes are less harmful than conventional smokes but not completely harmless, especially in those users with heart disease
- Those with asthma or other lung disease may have trouble with some of the chemical additives and should give them a miss!
- Aside from the uncertain health risk, e-cigarettes have literally blown up! Talk about lighting up!
- Sale of e-cigarettes are basically banned in Australia – either by outlawing them explicitly, banning sales of ‘cigarette-like items’ and by limiting marketing towards teens. That being said, the TGA has a method of importing a small amount of approved product for personal use. E-cigarettes that do not actually contain any chemical like nicotine can be sold, as long as they don’t make any claims to be ‘therapeutic’
So what does this all mean?
- E-cigarettes may turn out to be safer than ciggies but not completely
- Nicotine is HIGHLY addictive and a very difficult habit to kick
- Using them to quit smoking is possible, but using normal nicotine patches/gum/vapourisers are safer
- You can’t actually buy them in Australia – ones like I saw at the servo are non-therapeutic (that is for looks alone!)
So my call? Give them a miss. Nicotine is an unforgiving master. And if you’re quitting? Use the good stuff, chat to your doctor or call your Quitline. And good luck!
