It is difficult to say exactly which size jars hold how much marijuana. The problem is the variety of bud sizes, and how tightly you pack the jar. Generally speaking: 32 oz jars hold 1 oz. of buds. 16 oz jars hold 1/2 oz. 8 oz jars (60 dram) hold 1/4 oz. 4 oz jar (30 dram) holds 1/8 oz. 16-20 dram vials hold 1/16 oz. or 2 grams 10-13 dram vials hold 1 gram. *disclaimer: some dispensaries put 2x this amount in the same containers -- you really have to see what works for you!
