There are likely a few here who have tried it. Interested in your experience(s)! Did you meet other worldly beings... and did they trade? (You could use the SWIM acronym - Someone Who Isn't Me) SWIM tried it once, but not anywhere near a full hit. Visuals only.
I haven't tried it but I did watch the documentary on it on Netflix and it was super interesting to say the least. I think it was called, "DMT: The Spirit Molecule" or something like that.
I thought this summed it up quite well: The only way I can describe the experience: imagine for a second that you were a rat, just a regular rat, living a rat life, with a rat brain and a rat's conciousness and all of a sudden you smoke some shit out of a one-hitter with Joe Rogan... and you're infused with the conciousness you have now...
Try to catch one of the "machine elves". I want to see one! http://www.vice.com/read/dmt-you-cannot-imagine-a-stranger-drug-or-a-stranger-experience-365
