So, Ryan... ingested cannabinoids need to be processed, by my understanding, by the liver.
If your liver function is sub-par, you might not get effective metabolization.
Look for ways to strengthen & nourish your liver. I'm not a doctor, and I've never played one on TV, but I actually was a MANAGER for a Holiday Inn Express (*wince*)... in our house, when our livers need a little help, we take milk thistle extract. A real MD suggested it to me so long ago you might not have been born yet
... but, it's always been my go-to.
Perhaps, as far as edibles, you might try something that you absorb under your tongue, like a tincture, or try changing your timing of when you ingest.
There are three "times" that are supposed to have different, significant effects on how edibles hit you.
Twenty minutes before a meal (on empty stomach), With a meal, and 45 minutes to 1 hour after a meal.
If your digestive system is messed up, your stomach emptying time may vary.
One other method of ingestion might bypass all of this for you, and provide what you are looking for.
Suppositories.
One of the providers at the market we utilize makes them for medical usage. Inquire through your local dispensary (if you have one) or look up a recipe to make your own. This, of course, supposes that your lower tract is functional.
