DMT is the main psychoactive compound in Ayahuasca, the other main component in Ayahuasca is going into be an MAOI which prevents enzymes from breaking down the DMT when you you ingest it orally which also allows for a much longer trip because it now takes your body longer to clear out the DMT. There may also be some other alkaloids in Ayahuasca, but the main component is going to be DMT.
As much as I dislike Kapoor, technically Vantablack isn’t a pigment or regular paint by any means. From my understanding it is actually carbon nano tubes with who knows what else mixed in it and I believe it’s actually very dangerous to be around without proper PPE. So in that sense, it makes sense to me that he “owns” it.
Still don’t like the guy though.
