Well what i think most of you missed is that i was asking which type of pipe. Wouldn't ask that if there wasn't the assumption that it wouldn't light, but that doesn't mean it won't burn if you keep a lighter on it. I mean, ( OTHER STUFF NOT DISCUSSED HERE ) don't light but people still manage to smoke it. And anyways, i just tried adding PG/VG to tobacco, about half a ml for one 85 mm cigarette, enough to stop it from lighting at least. I put the tobacco in a ( OTHER STUFF NOT DISCUSSED HERE ) and was able to smoke the tobacco so long as there was a flame on it. Made the whole thing last alot longer than the same amount of tobacco without any PG/VG. At some point the PG/VG had vaporized ahead of the tobacco and what was left became lit for brief moment until it was pooched. If i can know which pipe to buy then i will try it with more liquid to tobacco ratio and will grind the tobacco finer. If i could get an electric-powered device, like a car lighter attached to vaporizer battery... Does anyone know of any 510 threaded car lighters?
