You folks using PG, PEG or any other related chemical product, including Wax Liquifier, are playing with your lives. I have a strong background in chemistry and pathology and several advanced degrees in these fields, and I can tell you that these products are NOT SAFE when used in eCig types of vaporizers.
While it is true that PG is considered GRAS (Generally Regarded As Safe) when used in various products including asthma puffers, it is not subjected to high temperatures in any of these applications. When PG hits a hot vaping coil, it is raised to a high enough temperature to cause it to break apart into several smaller molecules. Two of those molecules are carcinogenic. Take a look at this:

I have seen a lot of posts here trying to minimize the hazards of PG, some claiming that there is not proof that it's products of combustion are carcinogenic. To these posters I say "GET REAL". Unless you have sufficient background in chemistry, you are not qualified to make statements like this. It appears that, in your desire to seek the rewards of cannabis vaping, you have allowed your common sense to become sullied.
I use The Mighty manufactured by Storz and Bickel. This vaporizer, and others like it, used a controlled heating system that (at temps below 220 deg. C) does not allow the eliquid to get hot enough for the chemical reaction to take place. But of course, with a vaporizer like that, there is no need to dilute your concentrates with PG anyway
