I don't think your sensitivity to smoked DMT is even a good indicator of your sensitivity to oral DMT. Personally, I need a little more than some on the smoked end of things, but I can have a perfectly visually grand experience with amazing colors and patterns from just 30mg orally. Your body absorbs the DMT through two completely different mechanisms with smoking vs. orally so it may be better at one or the other. Also, body weight plays into the equation with oral more so than smoked I'm pretty sure.

Atum appears on the smell of his censing, the Sunshine- god has risen in the sky, the Mansion of the pyramidion is in joy and all its inmates are assembled, a voice calls out within the shrine, shouting reverberates around the Netherworld." - Egyptian Book of the Dead
