On the hobby side of the vape scene, there's a concerted effort to remove the 'cigarette' from the equation. A lot of the original modders started with flashlights (as far as I am told). Years ago I participated in a study to test the effects of smoke machines. I was working at a large arcade that threw huge parties with DJs and such on the weekend. Naturally, we had smoke machines. The researchers found that the PG had no effect on our respiratory system, which was actually what concluded that vaping would be a good alternative to smoking.
