Do people realize that everything is chemicals? Without them we die. Water is a chemical. There is a screw on the bottom of my
kayfun to adjust how much mixture of approx 80% nitrogen, 15% or so oxygen comes
thru to create the vapor. That's air, yet another chemical we die without. We all know what chemicals are in cig smoke and how many of them are killers. I'm kind of waiting to see the reports of respiratory illness increases in states where recreational other stuff is now legal. Most of that is used unfiltered unlike the filtered cigs most of us are quitting
