I mostly smoke changa 'Dream time' and sometimes crystal which is another level, Infinite.
Changa i say is like looking at the DMT.
Crystal i say is like feeling it.
I have only broken through on crystal, but rarely do i actually smoke to breakthrough.
And yeah some Peganum harmala, Syrian Rue seeds in the herbal mix will help make the Smoke Smoother also mint leaves are a great admixture, the Rue seeds also help disconnect and create space and increase peak time in my own experiments, agreed by friends who try.
I was told by an Ayahuasquero that when i start my ventures i should try both main ingredients separately first the vine and then the leaves.
He even recommended drinking a brew of Syrian rue by itself to try.
