Vape High - Wheres my Body Buzz?

I'm sure those last hits were pure ass

 

 
Why?   I've vaped where my ABV was darker than that and while not quite as tasty as the first two hits, they were still pretty good.   For me, the only time when it really starts tasting bad, like burnt popcorn, is when it's just a shade or two below black.

 

Must be my whip
(It hasn't been cleaned and it's been used a lot)

 

For me it goes downhill once it's dark brown.
I only revape golden colored ABV, uk, like yellow to light brown
