I tried a vape for the first yesterday (don't judge) I don't trust the stuff to be honest. It's not the tech, it's that I don't know the chemist and the ingredients are suspect. I did enjoy it though, I suppose I will now have to actually do the research and make my own juice. That's the only way I will trust it.
It's clear, that I don't even know how many ways there are to vape. The first time I encountered it was about 15 years ago, and it was a very different thing. It involved a large glass dome, and really was just to cool the smoke, which was ignited by a small electric emiiter.
