Not to mention the nausea that can accompany the crude cold water extract I used to use. Although a paste made of hbwr and jalapeno juice placed on the inner (opposite of) elbow and covered with cellophane for 30 min was almost as potent as oral. As it removes the gastrointestinal system from the mix, no nausea.

Makes me wonder if the stuff you had didnât have all of the contaminants washed out.

We donât use THC-O & Iâve always felt iffy about it, particularly for vapes.
But Vivimuâs article aligns with how I understand the legal side of it.
Organic presence in hemp / cannabis is not a requirement in any statutes. Itâs just consistent with that famous letter they published a year or 2 back.

They wouldnât have to be oblique about it. There are chemical signatures that can identify processed vs. extracted d8.

All the D8 THC currently on the market contains D9 THC, often 10% or more by weight. Itâs very hard to separate these compounds. D8 companies have preferred labs who consistently fail to report the D9.
If you test this with a decent lab (eg: KCA or Botanicor) they will find the D9 consistently.
You can be pretty sure law enforcement will find it too.
There is very little compliant D8 THC on the market and the higher price means it canât compete with commercially produced hot D8 with âfriendlyâ lab results.

The natural d8 content in hemp is actually higher. It is about 1/4 to 1/3 of d9, i.e. it generally lies between 0.05 and 0.25%.
But, indeed, it remains much too low to be extracted and conveniently concentrated.

Do you have any source on this info?
D8 is made from d9 by UV/light through a hydride shift so it would be more prevelant in high d9 cultivars then in high cbd cultivars

Thatâs if you assume thca production via thca-synthase, if itâs being made âoff recipeâ by the CBDa-synthase, one might expect (or explain) a different ratio.
There is i believe invitro data suggesting both synthase produce both CBDa and THCa from CBGa. Should be posted around here somewhen.
Edit: there is published data behind @sethâs statement
(I just canât be bothered finding it atmâŚ)
Running LOTS of hemp samples through his GC would be my guess. Given the chromatograms heâs shared in the past.

The plant isnt going to make d8 through an enzymatic pathway its all formed through a hydride shift which is why the more d9 you have the more d8 youll have

d8 is more thermodynamically stable than d9 so Iâll bet there is no biological mechanism at all for that isomerization.

" Hydride shift is a rearrangement of a hydrogen atom in a carbocation to make the intermediate structure more stable "
Uv has been known to be able to cause this
Which would mean the more d9 you have the more d8 youll get over time
Basically, what @cyclopath wrote above. 
7+ years of testing CBD flowers and extracts from various origins, almost everydays, always using the same method on different set-ups.
These are indeed unpublished data, so far. Plus one could argue that we only employ FID. Still, I believe I have seen papers dealing with this topic in the past. I will try to find some once back to the office. The few refs reported on the wikipedia page dealing with d8 are not valid ones.
D9 strains show a different profile than CBD strains.
D8 is indeed scarce, if not absent (generally below 0.01%) in d9 strains, despites a much higher (20-60x) d9 content. There are some systematics. CBD is generally 50-100x lower than d9. CBC is always higher tgan CBD. There is also generally more CBG than in CBD strains.
CBD strains show a greater variety of minor cannabinoids, with quite fixed ratios for a part of them. The CBD:D9:D8:CBC proportions fall in pretty narrow ranges.
I guess there are physiological reasons behind this. One could envision specific enzymatic pathways, or that the CBD strains would be more acidic than the d9 strains.

You got a reference for that.
The D9 in your CBD strain is absolutely made âoff labelâ (accidental ring closure) by CBDAS, why would that off label reaction always go to D9 if not constrained to do so as it is in the mutant (THCAS)?
The DATA says the ratio is different. My explanation works with that data, yours doesnât. Doesnât mean Iâm right. Probably means youâre wrong.

Why would this be if d8 is made from d9 by a hydride shift? Or are you implying the plant makes d8? The minor profile doesnt really matter when d9 is becoming d8.
Tells us what happens during processingâŚdoesnât seem to have relevance to the enzymatic production of THCA (D8 or D9) by CBDAS.
We know the D9 THCa is being made by the CBDA synthase. Why are you so sure that the more thermodynamically stable isomer is NOT made by CBDAS?!?
Because you wouldnât know biology if it bit you in the face?!?

I emited a few hypothesis after editing my comment above. Kind the same idea as @cyclopath.
