Really? I think I've had a lot in my system orally and never noticed that. How do you make the poppy tea? I used to just grind them, add hot water, steep then drink all the grounds and liquid for max benefit. Awful taste.
As a transdermal patch it's constant and very good for chronic pain, not acute pain, but even for that it probably helps. Ever since I had a patch I keep bumping into things too, dunno why, it's a long time now.
I've tried many pod tea methods, I strain it, never ate the ground up pods. Currently I find the effort:effect ratio is best when I put the powdered pod in a flask with boiling water and shake it, leave it ten minutes (I figure most microbes are dead by ten minutes), strain and repeat.
Only until I get another smoothie maker/coffee grinder when everyone sells their unwanted christmas presents in January.
Once I have one of those, I'll grind the pods in the smoothie maker then add boiling water directly and whizz it all a few minutes until the water is dark. Done that way the second rinse has almost nothing, seems it all goes quickly into the water with enough heat and friction, but the pressure needs released a couple of times or it might explode boiling water everywhere.
My old smoothie maker never had any other plant near it

gave up within it's warranty, but it was so dark brown around the edges I didn't send it back, lol.
Then there's the expresso method, but usually I can't be arsed getting out that and waiting by the stove for it to go upwards. I think there is too much heat in that method, destroys some with the heat of the steam imo.
I think any coffee method can be used, it shouldn't be burnt, same as coffee. Dissolves in hot water, same as coffee.
As awful as the taste is, I actually quite like it, it's the association I guess, it's unique.
It only came up again once, maybe a year ago, but I was well into withdrawal at that stage and panicking about how I was going to get that tea into me if my stomach wouldn't take it (one of my failed attempts at quitting, my stomach was ok second time).
