I've had a few ever-lasting bowls, a lot of it has to do with how you crush it up and the quality. Chronic burns up sooo fast, the frost seems to incinerate a lot faster then on reg.

Also, if you grind up your chronic you'll get some BOMB hits, but it'll scourch up quicker then anything. I dont usually grind up my chonic if im smokin with friends. Bust it up to smaller balls (not too small) and you may have to light it a few times but it lasts longer and few people take notice.... unless you just throw a nug in there.

A friend of mine bought a dub of reg and he didnt want to sort through seeds and stems so I said i'd do it. I got out all the seeds and stems (even thoes little micro shit stems) and finely crushed it all up to a fine dust (well half the sack). It was basically kief, this stuff couldnt get any finer. But I packed like a whole gram in a bowl because it just kept packin down, you can fit a lot more dust weed in a bowl then nug weed. It burned kinda strange, you could tell it was gonna take a while to get through it lightin up greens. I cant really remember how long it lasted but we all agreed it was the longest bowl we'd ever smoked. Hit like a mofo too.
