for me, the distinction is that a dab is a quick whoosh of a lot of product at once, that can only be done at high temps. it may or may not be partial combustion.
vaping concentrates, for me, has always been limited to using my regular vapes. and these always take a long time to consume a dab. I just ran a medium sized dab through a vape into bags and I got 12 hits before I started to feel like it was thinning out any.
but this is just how I see it and talk about it. are you guys the same, or do you see it differently? So when the OP was at 550, which is only 100 above my max of 445 on Herbie, I wonder at what temp it ceases to be a dab and instead is a series of concentrate hits from a vape?
