Thanks Xorkoth, I've read and re-read all your posts about the comparisons of 4-aco-dmt to 4-ho-dmt and I completely agree. The 4-aco-dmt knocks me out (makes me pass out at high doses) and makes me drowsy at low doses as well, I even find my breathing shallow at time on the compound, it's not very visual to me, and is dark and sedating compared to the stimulating, enchanting, and very visual nature of 4-ho-dmt, I find it very similar to pan cyan mushrooms which are about 60% psilocin, 20% psilocybin, and 0.002% of the funky and bad feeling/paranoid thought confusion causing baeocystin and norbaeocystin. On my last trip of converted to 4-ho-dmt I had a 3 hour trip with 2 hours of CEV's brightly colored that revealed religious temples and I was taken on a tour of old civilizations (mayan and aztec), inside the Mayan architecture I viewed artifacts that were brightly lit up, it was like walking thru an art exhibit or museum, it was brethtaking, my ego is always challenged a bit for the 1st 15 minutes or so of the trip, but then it mellows out to a highly visual journey, sounds are quite hallucinatory as well.
