GVG is better than VG, for obvious reason, that user can see through it (loves to watch vapor circling around in cooling chamber), therefore he has better control over dosing. And it is nicer than VG, better design (makes him to keep it clean)

I vap. nicotine with it, believing it is healthier way of administrating the drug. (No more cigarette sucking for me ) And it's great for free base anything too.

By the way I don't get stoned, so I brought GVG to THC 'veterans' for testing. They called it 'expensive glass stupidity' before they tried it. After experiencing dense THC vapor (gunja) for first time, they started to call it 'The Genie' :d and agreed that it is most efficient way to do THC. We finished test by trying to smoke gunja leftovers from vaping and it tasted like to smoke field grass. No goodies left in plant material. After test I've hit them with 'Changa from The Genie' with was definitely peak of that evening
