12 grams. i used a blunt roller machine, and it ended up being packed so hard that you could barely even pull on it. We smoked half of it and decided to just put it in bowls instead.
My frineds went through a time when they tried to pack as much as possible in to a blunt. You don't get half as high as you would if you roll a few good blunts and pack a few bowls.
idk, but i've smoked a giant joint about 6g and it was so big that it was falling apart so we just packed bowls of it
