Routes of administration of DMT and its principal psychoactive experiences as reported on http://www.erowid.org [71].

DMT EXPERIENCES
Route of Administration	Dosage	Effects (up to 1 Hour)
Oral (>350 mg)	up to 350 mg	“Completely without effect either physiological or psychological”
Intramuscularly (60-100 mg)	with 80 mg	“My perceptual distortions were visual in nature and with my eyes closed I could see colored patterns, primarily geometrical patterns moving very fast, having sometimes very deep emotional content and connotation. My blood pressure went up and my pupils were dilated.”
Subcutaneously (60-100 mg) (via the buccal mucosa)	with 100 mg	"Numbness at the site, but no central effects.”
Intravenously (4-30 mg)	with 30 mg	"I was hit harder that I had ever been when smoking the stuff. The onset was similar, but the euphoria was less."
Smoked (60-100 mg)	with 100 mg	"As I exhaled I became terribly afraid, my heart very rapid and strong, palms sweating. A terrible sense of dread and doom filled me - I knew what was happening, I knew I couldn't stop it, but it was so devastating; I was being destroyed - all that was familiar, all reference points, all identity - all viciously shattered in a few seconds. I couldn't even mourn the loss - there was no one left to do the mourning. Up, up, out, out, eyes closed, I am at the speed of light, expanding, expanding, expanding, faster and faster until I have become so large that I no longer exist - my speed is so great that everything has come to a stop - here I gaze upon the entire universe."
