We use pretty large turkey roasting bags so many may be possible. We only needed one good inhale each for a breakthrough. How many inhalations were you needing?

Edited to add- There is still a lot more tweaking to find out how concentrated you can get the bag and not burn the dmt. The volcano is not at my disposal so I only got to play for a little while. I will say that I feel infused leaf or changa is a much better way of using the volcano than dmt freebase in which I havent heard too many good things. Re-xing in the bag is nasty stuff. Changa doesnt seem to do this as much if at all.
