No there's no need for a special diet with changa. Since the MAOI goes straight from your lungs to your bloodstream, it doesn't interact with the food (and the tyramines) in your stomach like it might if you were taking the MAOI orally.
And actually some say that since it's a reversable MAOI, you don't really even need the diet for oral dosing. But I don't know the truth of this for certain so I still do it.
Edit: oop someone beat me to it

No direction but to follow what you know,
No direction but a faith in her decision,
No direction but to never fight her flow,
No direction but to trust the final destination.
