Finished munching for now. Saving a few pineapple cubes from my bag for later. Currently not eating so as not to reverse the effects caused by the last bong bowl I've got, and am about to hit. Wish it were proper bud though, this is inert herbs, soaked in a mixture of AKB-48 and 1-(5-fluoropentyl)-AKB-48. Pausing after the first toke to go make and eat a marmite sandwich on brown bread, and a jug of lime cordial, before going to blaze the remainder of my bed time bong.
And more tinned grapefruit.
Yes, a fair few of the flavonoids within grapefruit, such as naringin, quercetin (IIRC) etc. block both CYP-3a4 and 2D6. Both are involved in metabolizing morphine , and other related opioids. Actually I am unsure with oxy, undecided. As oxycodone is certainly active by itself, given how effective, and in what timescale, when injected IV/IM, subcut or plugged rather than orally, denying it the chance to not show activity of oxycodone, and stopping if inactive, a mandatory wait for hepatic metabolism to occur.
As I'm uncertain about the precise metabolic fate of oxycodone, I tend to take it first, let it act, and then after that has done so, then take the morphine, whilst swilling down the canned grapefruit and GF juice/fresh fruit.
Works on benzodiazepines also, via CYP-3A4i, there may be exceptions, to that, but if there are any I would predict it to the fluorinated kinds, as th C-F bond is tighter than a 10yo nun's minge, does not like to split away from most elements, but especially tight bonding to carbon, F is often used in research for the purpose of a 'fake hydrobut same electronic configuration' so it can behave as a hydrogen native to the molecule being studied, but one that cannot be removed by living metabolic processes
