I did 2 sessions with DMT directly after 2 sessions of salvia before without any noticeably diminished affects.
But don't write off mixing the two. I find they can compliment each other nicely in a mix, especially if you use caapi and make changa with the salvia. I like my mixes light on the salvia and heavy on the DMT.
I have not tried salvia after DMT yet, I may have to try that.
Its the MeICNU
