I use a Vaporstar for DMT and have noticed sometimes while inhaling, a sudden large ammount of thick white smoke appears into the pipe. It just all floods through within a second and I wonder why this happens. Is it that DMT is burning? I didn't think this could happen on a vaporiser, but I really don't know what is happening. I'm inhaling then suddenly this nasty tasting dusty feeling thing is in my lungs. Tastes very different to DMT and even feels different while inhaling, if that makes sense. Feedback anyone?
