Thank you, you're a sweetheart!
Ok, just found it - the one I
love is very British - and very pure!!
It's -
www.intellicig.com and they have a box at the top that you can see it all in US$ etc.
It seems expensive for the initial outlay - but is minimal in comparison to the cost of 'real' cigarettes. Also, they suggest you purchase the 'empty cartridges' to put the eco-pure liquid in. You don't need to do this - the e-liquid works just as well with the pre-filled cartridges.
There's a lot of very detailed information on their website, including a section on health, contents, frequently asked questions etc. It's certainly worth a browse, to put your mind at ease.
Please do have a look at it - and then I'll talk you through the finer details, if need be!
