How many grams of marijuana is in a joint?
You would usually roll between 0.2 and 0.7 grams in a joint. It
really depends on the size of your joint and if you mix it with
tobacco or not. Really just roll whatever fits in the paper, and if
you have too much to smoke light it out and you can use it
later.
There are some pretty big joints being rolled out there too,
like a whole ounce into a joint. It can get a LOT of people stoned
and will burn for a really long time.
