don't roll it, you wont' get nothing from rolling it...

how many uses in a gram? well lets see.. i've had mine for a few months now..
5x me
2x wife
2x brother
3x friend
4x assorted users not doing it right and "wasting" it...

still got atleast 1/3 of a gram left.. so roughly 20 diffrent uses.. depending on how much you smoke each time, lung capacity, and so on... i always loaded up a full bowl in my small glass spoon tho and once it's hit, even if it still has foilage in the bowl i dump it out, seems after the first hit all of it loses any potency it had..
