ok, there is an issue with black seed / nigella sativa in that there are a couple of varieties of seeds that go by the same name.
this thread has a link for photos of both the commonly found seed (inactive) and the ones you want.

now, a few months ago i went to my local bulk foods store and got a bag of black seeds. upon viewing that thread i realised they were the wrong kind - they were sort of round.
i remember that there were two similarly named seeds in the store, so i went back and got some of the other ones. they had a skinnier, pointier shape, and were smaller seeds.
"black seed oil" has proven hard to track down in my area - and you are still stuck with the same issue - the oil could be extracted from either of the active/inactive seeds, and you can't really tell.
so, i thought i'd experiment.
i put a small amount of nigella sativa seeds in a bowl with some honey and chewed it up.
next time i will use a blender or a mortar and pestle, because chewing them was a bit tedious, and i ended up washing the half chewed seeds down with water eventually. there was about three mouthfuls of seed, so not a huge amount.
an hour or two later, i made some PST. now, i maintain my habit with poppy seeds - i neither get high or feel much from them on a daily basis. i would say that at most, i get a sense of feeling 'nice' or 'right' from them (ie relief from the onset of withdrawal) but very little else. i never get stoned off of poppy seeds, no matter how much i dose. i barely feel it, except it takes away the restless leg feeling of WD and calms my body and mind. i've been using them and other opiates for about 10 years.
anyway, i had my normal dose of PST - maybe a little less. i usually make a batch, drink about half and put the rest in the fridge. i often go back to the fridge and drink about half of that after my initial dose, depending on how well it works to make me feel ok.
yesterday, i only drank the initial dose - no more. so, about half a 'batch' of PST - maybe 500g of seeds.
drank it a bit over an hour after eating the nigella.
an hour or so after dosing the PST, i was very, very high.
nodding, sleepy, pinned-as-shit eyes. dry mouth. i was fucking loaded.
this is most unusual, and i would say with absolute certainty that if you get the right seeds, nigella sativa is a great potentiator.
i didn't need the expensive oil extract - i just crunched up a few mouthfuls of the seeds with honey. it wasn't that pleasant to chew the seeds for ages, but it tasted fine and wasn't difficult to do at all. when i got impatient chewing the seeds, they washed down with water with no trouble.
for folks that need to stretch their opiates further, i would recommend this stuff. granted, i've only tried it once, but i was blown away by how well it worked. i don't know anything about long-term effects, what it may do to tolerance or if there are any other potential health concerns - but i will say this:
be careful not to overdose.
next time i take nigella, i will have half my normal dose. i was amazed at how well it works, so it would be irresponsible not to warn people. half your dose or you may have trouble breathing or staying conscious.
i took a dose that i take daily (which normally has little psychoactive effect) and i felt sleepy and heavy and was nodding.
this stuff seems like it could be dangerous if used in combination with a large dose of opiates. i don't know if it works the same for all opiates/opioids - but there was a definite potentiation with my cruddy little dose of PST.
i say it works - but please use it with care!
