Thanks for sharing your DMT vaping experience. I am the organizer of the Sacred Plants and Psychedelics Meetup in Honolulu, HI, and I have also used a DMT vape pen. The immediate effect and short duration appealed to me, and a friend and I tried it together. Unfortunately, neither of us had a typical DMT trip; we both became sexually stimulated, so clearly there was something in the pen, but there were no visuals, no entities to converse with--nothing of that sort. The only other DMT experience I had was an abortive attempt to insufflate finely ground powder from the root bark of the Acacia confusa tree. Although theoretically that might have some effect I strongly recommend against it--I ingested only a tiny amount and the pain was too excruciating to continue. I do look forward to the opportunity to smoke it at some point, but that opportunity hasn't yet arisen.
