It depends on how big you roll your blunts.

An 1/8 though is 3.5 grams of weight, about the bottom layer of a sandwich bag, maybe 3/4 of an inch in height.

Usually though, a joint is $5, which is .5 of a gram, so you could roll up 6-7 joints with an 1/8.

Blunts though, tend to be bigger at about 1-1.5grams worth. You can put much more than 1.5g's, I'm just talking minimum amounts, so blunts worth, about 3-4 blunts with an 1/8.

So really it all depends on how big you roll them, but just do the math from 3.5g's and try to eyeball how big and how many you can roll.
