Thanks for posting the link. I will miss him.
It's sad that nothing changed once the states got their cut!

He said it changes when burnt. He did not say it changes when heated. Is the temperature inside a cartomizer or atomizer as high as a burning cigarette? Does the ecig produce acrolein?

good questions- same questions I have

this has come up on this forum numerous times before. at the temps that we vape, glycerin, glycol, VG (all the same thing) do not pose any danger and does not change chemically to be carcinogenic.

That is my understanding also. I read rolygate's thread on this and Ecopure's tests for this chemical in their vg liquid. None was found.

I believe that acrolein is not carcinogenic but is toxic and highly irritating. If you run a high-voltage device with a low-resistance atomizer nearly dry for many seconds, you can get it to burn VG into acrolein. The stuff is very acrid smelling and will really irritate the throat/nose if inhaled. Vaping temperatures do not create acrolein. If they did, you sure as hell would smell/taste it.

My experience with VG-only base liquid leads me to believe that acrolein is most likely produced in minute amounts when I get a 'dry hit'. As chad said, you'll know it, as it's very acrid and irritating (even in tiny amounts.) It's utterly horrible if you dry burn an atty without rinsing out as much VG as possible first.

Since it's an easily recognizable taste and odor, it's pretty easy to avoid, IMO. Avoid dry hits, and dry burn in well-ventilated areas.
