It seems as if 'vaping' came out of nowhere. One day it didn't exist and then a few months later everywhere we went someone was vaping. In reality, electro-mechanical cigarettes are not new. Neither is the concept of using vapor to breathe in smoked herbs, scents, or mild-poisons. In fact, that has been going on for as long as mankind has been keeping a written record, perhaps even longer. There are accounts of such techniques in ancient China, as well as in ancient Egypt. The Romans often smoked in bathhouses, and in India 1,500 years ago, they called smoking sugary tobacco 'shisha'. https://terpsusa.com/
