How big is one ounce of marijuana?
Despite our opponents claims that 80-some-odd marijuana cigarettes or joints can be produced with one ounce, the National Institute of Drug Abuse considers an average joint to be 0.895 grams. Thus, one ounce of marijuana (28.5 grams) would make about 32 marijuana cigarettes. Obviously it would be possible to roll one ounce into a couple very large joints or far more very small joints.
