Let's Have a Science Lesson About E-Cigs - Comments

You are right, but an Ecig almost killed my mate xD So they are pure evil, haha. They are a good idea, I wanted to get on them, but I tried one when I was at uni and to me, it just tasted like licking a battery. LMFAO.

Flavoring is just that, flavoring. Tons of people use all kinds of flavoring in baking.

I'm always cautious whenever I see ANYTHING that states on it's ingredients that it contains "flavouring" because a lot of chemical things can be hidden under that name.

Edit:

This is sort of what I mean with not trusting flavouring, because flavouring can be a lot of things. It also brings up this point which is something I didn't know:

Caution: flavourings

Food-grade flavouring compounds are, by definition, not tested for inhalation. There are likely to be health implications resulting from inhalation of some flavours, and right now we do not have a complete list of the problematic ones. At least one is known to be extremely hazardous to the lungs (diacetyl) and there is no reason to suspect it is an isolated case. Because too little is known about this aspect of vaping, ECF cannot advise you in detail on this issue; but we do know that as well as butter-popcorn the creamy, buttery, custard-type flavours will probably entail risk even if diacetyl itself is absent (because this group of flavours has a question mark regarding safety).

This flavour group includes diacetyl, acetoin, and acetyl propionyl: the dairy, creamy flavours. Realistically, we do not know if there are any safe flavours for inhalation in this group.
