Talking of the top of my head, with no real knowledge on the subject, other than I have read loads and loads about these things for many years, I would say emphatically NO. I can not imagine for one moment, that if there was DMT in acacia seeds, we would know about it and be talking about extractions already. People have tested all these plants already. They have published their findings with regards to root bark, branch bark, seeds and leaves. Nobody found it.
I am a clown, nothing I say can be taken seriously. It is my profesion to talk nonsense
