not 20 oz, dumbass, thats 1 and 1/4 lbs of marijuana. A 20 bag is $20 worth of weed, depending on area, and tiem of year, the actual weigth will vary

rather than just marijuana, a '20bag' denotes a deal of any illicit substance to the value of £20 / $20 and could just as easily contain rock, powder or tablets.
