They won't be selling anything to me that's for sure.
I can't find any peer reviewed study of their findings just some abstract using a sample size of six plants. The link to the white paper on the DHN website just takes you to a page to place orders and wait for the next "Drop". I got a chuckle out of that. I also found other labs that will charge you to test for it.
I'm not convinced at all that this exists in cannabis and if it does that it's as big an issue as these companies offering testing and cures is making it out to be. All of the information traces back to a very small group of people and no independent peer review can be found. Literally every link is using the same information that came from one source.
