I'm sure this is of no use to anyone since no-one knows where I live but...
I went into my local newsagents today and on the counter, they had electronic cigs in mild, extra strength and menthol...with a sign saying "Try me for free".
I was thinking "Eww...why would you want to puff on something that's been in other people's mouths?"
Then I noticed a bag of disposable clip on mouth pieces...a bit like what Police use on breathalizers.
Anyway, I just thought it was a really good idea and thought I'd share it 
Good luck to everyone giving up smoking and taking up vaping
