I'm starting to treat my lymphoma with THC/CBD oil. I'm using concentrates from a local producer. (Love living in Colorado!)
I just stumbled across information about how cannabis is metabolized, and how it may interact with cancer treatment drugs. I've been reading a bit about CYP enzymes -- liver enzymes that deactivate/metabolize drugs. I don't understand much of what I'm reading, but apparently THC and especially CBD are "potent inhibitors" of these enzymes, see e.g. Cannabidiol is a potent inhibitor of the catalytic activity of cytochrome P450 2C19 - PubMed. This can effectively result in an overdose situation.
I'm not taking traditional toxic chemotherapy, thank God. I'm just starting Ibrutinib and Venetoclax, which are considered "targeted therapies." I don't know 100% for sure if they actually have strong interactions with cannabis. But they can have some fairly nasty side effects, and I don't want to risk a potentially dangerous dose.
Does anyone have experience or solid knowledge on this?
From what I've learned in the last few days, cannabinoids are usually metabolized in the liver, which extracts all the psychoactive goodies and sends them on to your brain &etc. **BUT** supposedly (I'm seeing conflicting claims on this) rectal suppositories do NOT go through the liver, but are absorbed directly into the bloodstream through the wall of the colon. That way there's no interaction with the CYP enzymes. It also avoids the psychoactive high, which is fine with me -- the dosage required for anti-cancer effects is just insane. I've been trying to build up some tolerance for several weeks, but it just whacks me out. Currently I'm using 73% THC concentrate. If I take a "2 grains of rice" dose before bed, I'll sleep well, but the next morning I might fall on my face getting out of bed. I stagger and stumble around for a while before I can navigate safely. I'm loopy for 14-16 HOURS after taking the dose. And I'm supposed to take 15x that much every day!? Rectal dosing sounds like a much better idea. *IF* it keeps it out of the liver. If not, I may have to drop the idea.
Thanks for any pointers --
