It wouldn't work, the DMT will still be eaten by the uninhibited MAO in the stomach, smoking harmalas won't inhibit the enzymes in the stomach you need to eat it, if you took both orally then if the experience was not strong you can smoke harmalas to boost it, works great
"Is this the end of our adventure? Nothing has an end. We came in search of the secret of immortality, to be like gods, and here we are... mortals, more human than ever. If we have not obtained immortality, at least we have obtained reality. We began in a fairytale and we came to life! But is this life reality? We are images, dreams, photographs. We must not stay here! Prisoners! We shall break the illusion. This is Maya. Goodbye to the holy mountain. Real life awaits us." ~ Alejandro Jodorowsky
