Smokeing DMT after eating 3g of rue (peganum harmala)
It is also an MAOI of sorts but also much more, and it falls in the grup that requires no special diet.
then just n,n-DMT
Ayauasca is not as intense as DMT, but the duration is several hours which may make it a more traumatic experience for some, also it is less visual, but the longer time gives more time for slower visions.
That I'd say followed by the CEV of cannabis, sceletium and MDMA.
Then thirdly acid and shrooms (in fresh and high dose).yep I've seen mountains reshape and the sea inverting into an electric blue blanket, and streets break up and houses drift downstream on rivers of magma... but its still only 3rd.
There may well be a host of other synthetics and RCs that could be more visual.
I find salvia all fucked up on too many levels.
