Since you also seem to be the intellectual type, I wanted to give a thoughtful response... Growing up the son of a hippy and amateur chemist, I learned about every drug and plant that is psychoactive. My dad was making THC honey oil before I was even born almost 48 years ago! Anyways, I learned about many cultures that embrace hallucinogenic, psychedelic and entheogenic plants! ALMOST every culture through out history has used some kind of psychoactive substance, often reserved for the Shaman, Chief, Priest or Witch Doctor! The psychedelic effects help them transition into the spirit world in order to see visions and even divination. So, ABSOLUTELY, a rare black phenotype, especially if it's extra SUPER potent, is going to be considered sacred! The high priest/cheif might not want even his OWN tribal villagers to indulge, let alone outsiders to get it!
With that being said, my friend in Africa did say he was going to phenohunt for an African landrace strain called DEATH!
He said they use it to go into a trance to enter the spirit world! Indicating to him that it's probably high in THCV! I'm trying to get that one too, but he hasn't gone on the expedition yet. He just moved, so I think he will go in the near future, or hope so anyways.
Very intriguing about the plasma treated seeds. I will see what info I can dig up.... Question is WHAT kind of plasma? Electrical...?
Happy growing brother!
