Inhale, Kizzy, not ingest, ingesting means swallowing /toysoldiersplain

But yes it is really odd that they were allowed for mass public use without any real testing. I also think a huge issue with them is that people don't use them the same way they would smoke. With smoking most people would light one up every so often (very few people would actually chain smoke all day long) whereas with the vaping because people feel like it's safer and it doesn't make you feel sick to overdo it like smoking does, a LOT of people are literally puffing on their little machines non-stop all day. I wonder if in an autopsy, the lungs of a "vaper" would be dripping with vape oil in the same way that smokers lungs are full of tar?
