Hundreds or thousands of years ago, indians and chinks had elders who figured out eating this common seed, or one in the family of it made them high as fuck.
They passed this knowledge on, it became "hidden" or "dark" knowledge, similar to the effects of cannabis on humans, and it wound up in the hands of freemasons, rosicrucians, etc.
same thing with cannabis, same thing with ayauasca, etc etc. Freemasons, rosicrucians, nxium, they are all trying to figure out if some prior civilization had more info than we do.
These days, scientific experiments on humans aren't ok, so to reproduce and extend on dark knowledge obtained before the crusades, they need human guinea pigs.
Division of "dark knowledge" had freemasons with cannabis, rosicrucians held on to knowledge of using lights and patterns of lights for medical purposes, possibly even for mind control, and indians had opium and similar drugs
