Where in the quality range does 'chronic' fall?

Isnt chronic just dank shit?!

Yeah, out here Chronic is the name slapped on any high grade stuff, unless its that name brand danky dank nugget.

I love BC, we just have pot here. If it sucks then it's called shitty weed. But for the most part unless you're buying off the crackhead downtown you are going to get good pot. Chronic here is used as a synonym for pot, or as an adjective synonymous to dank or potent.

Really the whole mids, highs, whatever-else-there-is thing seem strange to me. Is it an American thing or do we canucks use those as well?
