The 'e-juice' used, uses flavours that contain chemicals that in my mind have not been researched enough even though I feel that there is a miniscule chance that they could be hazardous. There needs to be more control and more research done on this aspect. These flavours are used in everything most people consume in everyday foods nowadays but I still have a niggling concern on what impact they will have on us taking them in as a vapour rather than eating.
I smoked very little before, but with the new e-cigs I'm finding I'm enjoying puffing on these a lot more and therefore probably taking in more nicotine. Having said that, nicotine on it's own, has been proven to be no more harmful than caffeine and as per earlier thread, although addictive, research has shown that it actually can be GOOD for people with certain conditions believe it or not. However there is no way you can work out how much nicotine you are taking in, compared to tobacco. You may be getting much higher hits of nicotine than with tobacco cigs, or possibly less. Nobody really knows at this point.
The laws in Australia are that you can have e-cigs with ZERO nicotine in the e-juice and nicotine liquid is illegal to sell, BUT you are allowed to import enough for 3 months use from China or the US.

I imported 300ml. from China so I can mix it with e-juice using simple maths. For me this amount would be enough for a couple of years. Problem is, there are knobs out there whom you can guarantee, will get the formula wrong and make themselves very sick. Also it's a hazardous material that could kill children or pets for example. Having said that there are tons of chemicals around any house that could do the same thing. e.g. bleach or anti-freeze.
I have had quite a few amusing episodes. Just one example. I was catching a late-night train home where they have a security guard in each carriage. I puffed on my e-cig and the guard looked at me very uneasily and would avert eye contact when I looked back. He either thought I was a lunatic or maybe he knew that e-cigs weren't illegal in public places.

Some passengers were confused to say the least. In Australia you can 'vape' in public places like airport lounges, pubs and other public places legally. However not all places know what to make of it.
I know the above just adds to the complications and I'm muddying the waters probably unnecessarily. Considering everything I still give them the thumbs-up.
