A bowl is cashed when no smokable material remains, only ash and residue. “After three hits, my bowl is cashed.”

What does its cashed mean?

(slang) Exhausted or used up; finished, empty. That bowl is cashed.

How long does a bowl last?

If it's 2/3 full, it can go an hour and 15 minutes, even if the tobacco is drier than it should be. Everyone says smoke slow, for several reasons. A lot of people here also say they finish in 30 to 45 minutes--and that's for full bowls!
