I thought so too until I combined super doses (more than 300ug, closer to double or triple that) with high grade pot. One time I took some acid, I actually hallucinated not only visually but also aurally JUST BEFORE taking some bong rips of heads, and then after the bong rips, it was as if I had just recently come out of a breakthrough DMT trip, but for hours. Usually on a regular or moderate dose of L I stop tripping hard around seven hours in and can usually sleep by hour 9 or 10. These times I would still be getting OEVs at hour 12. I posted earlier that LSD + DMT would be my choice however in retrospect I think high dose LSD + good pot is just as visual.
If you are talking DMT alone vs LSD alone, well yah, DMT all the way.
I sorta fucked up my techniques the one time I tried syrian rue (orally) + DMT, it was low dose of each and I was coming off of mirtazepine at the time, still was wonderful.
I want to try changa in the future, it seems universally amazing.
