I was out and about today and noticed that fog machine juice is widely available right now for Halloween. This got me interested in other possible uses for fog juice, possibly as a base for homebrew 0-nic e-juice. I looked up the MSDS for a couple brands of fog juice and checked the CAS (Chemical Abstracts Service) numbers (the ingredients were listed by CAS number, not by name), and it appears that fog machine juice really is just propylene glycol, glycerin, and water. Is there any known good reason why I shouldn't buy a gallon of this stuff for $20-$25, divvy it up into dropper bottles with Lorann flavorings, and vape the heck outta it?
The website I was looking at says they use pharmaceutical grade ingredients and de-ionized water.
