hey guys, i've been putting off my DMT extraction because i've been unsure as to whether the "Ace VM&P Naptha Pure" brand is actually pure or not. i left some out to evaporate in a shotglass and there was no residue leftover that i could scrape up, but it did seem like the bottom of the shotglass was left with a white-ish tint to it (but nothing came off the shotglass when i tried to scrape it)... can anyone verify that this specific brand is pure? i want to make sure i have no nasty shit in my extraction when i do it for my first time. thanks!
