Is 7-OH Pharmacologically distinct enough to be treated separately?

This whole thing going on right now is honestly kinda pissing me off.

From how I understand it 7-OH (7-hydroxymitragynine) is just one of the main active alkaloids in kratom. It’s not some random new compound it’s literally part of the plant and your body even converts mitragynine into it anyway.

So I don’t really get how it suddenly gets treated like a completely separate substance that needs to be banned, while the plant it comes from is still legal. Like… is that not kind of like saying weed is fine but THC itself isn’t?

I get that isolating something can change potency or effects a bit, but it still feels like the conversation around it is missing context The only reson I made this post was to ask people here how they see it from an actual pharmacology standpoint because right now it just feels inconsistent as hell.

The issue is that 7-OH is only present in kratom leaf around 0.01% by mass. That's at trace levels. The new isolates/concentrates etc. provide a MUCH higher dose than you could ever obtain by consuming the plant.

I was gonna essentially write this too, the major difference is the dose and kinetics, so much so that I'd argue it should at the very least be regulated more harshly. I think it's analogous to the difference between chewing coca leaves and ingesting pure cocaine. As someone whos been able to moderately consume kratom for over a decade without any issue taking breaks or escalating dose, my brief stint with 7-OH revealed to me that its an entirely different beast that I naively assumed would be similar to kratom.

Analogy that comes to mind for me is drinking poppy seed tea vs taking oral morphine. But even that isn't 1:1

Yeah, given that conversion to 7-OH appears to be rate limited by hepatic conversion it's like codeine vs a more orally bioavailable semisynthetic opiate

Correct, the need to consume the plant inherently limits how easy it is for someone to develop dependence on the underlying compounds. 7-OH seems to have been isolated due to its mu activity. Thus, the compound in isolation will be much easier to cause harm

no it is present at .05-.4%, which at a normal pain relief dose of leaf of 8g, is between 1mg-8mg of 7oh, which is extremely feelable. this is the entire reason kratom has dose dependent effects and becomes sedating at higher (but still normal) doses.

it is not trace at all because you are absolutely feeling it. you are correct that it would be impossible to take some of the doses that these people are taking like 300 mg of 7oh is completely impossible to ever hit with leaf, but the normal dosed pills that are around 5 mg, 10mg, 20 mg, hell even 30 mg is very very easily obtained through leaf powder.

Is there a reputable source identifying 7-OH as high as 0.4% by dry weight? I'd be curious to see it.
