Does using a bong waste weed?`

[chrons]

I usually hold it for about 20 seconds. How long do you folks hold your tokes?

20 seconds is probably not needed, I actually heard 5-7 most

but anyway, your friend probably just said bongs waste weed because they CRUSH bowl packs, not because THC is lost in the water or sides of the large device, that's all some BS, I almost guarantee he said it because you can easily crush a whole bong pack compared to a bowl in a pipe or even a bubbler...
