Sounds tough... I'd definately would smoke very little of that changa if possible. Have others tried it like he did(full hit) and how were the results? I mean did you girlfriend smoke it "in full manner" and were there others who tried it?

It could be also possible that your friend took very large hit and that he caught it into his throat by a cough.

Could it be that there were some preparation step done incorrectly and that there were some impurities or something that caused harsh smoke?

Glass VG isn't that much more expensive including the tax and shipping charges.

I am european myself and paid about 120 euros for the pipe including all expenses. Definately worth it for such a beautiful and perfect piece.

Ask member hyperspace fool by PM how does he use his bulb vaporizer, because he has claimed that it works just as well as GVG.

Sublingual is under the tongue, you just put about 20mg of caapi extract, wait a little, then vaporize DMT.
