Interesting post, I know there are a few kinds you can use and I'm interested. The funny thing is they are illegal here to sell, but I still see them in some smoke shops.

So is it water vapor or what?

I think it's a great idea if it's safe and doesn't cause other issues health wise.

And for all the non-smokers, please reserve comments as it's a horrible habit and extremely hard to escape from for most people.

Those who have awesome work.
