People just don't know.
We call it vaping. People that use 'other stuff' call it vaping.
Both groups know the difference - the general public does not.
The worrisome part to me is the general public - and now the users of "other stuff" not being informed that vaping oils is BAD like WE know vaping oil is bad.
I was reading up on the latest scare this morning. Saw one site that sells all sorts of vaping gear. The one that is legal in some places, the one that is legal in most places, and nicotine. The site said their vape pen was suitable for use with XXX vaping oil, YYY vaping oil, and nicotine vaping oil. I saw the word oil on several different sites as I looked around. I've seen new members here talk about vape juice as oil.
I've seen the same confusing use of terms on sites that sell the mostly legal one. Our nicotine vaping sites are normally pretty good about the terminology.
Apart from the more technical definition oil is a generic word for thick viscous liquid, and vape juice looks and feels oily.
Trouble is people see those references and don't get the difference.
