I was just looking for a few pictures of nicks , dimes, dubs, and oz's to compare cause it seems like shit keeps changing in price and size. Just post some pics of ur shit.
size varies a lot, sometimes an ounce will be a full sandwich bag while other times it'll be half a sandwich bag.
A pretty decent sized joint is a gram.... Out of a "nick," bag, it should be just one joint. Out of a dime, 2 joints, and so on. That is the best I can tell you, but some people weigh out their shit different. Just find the average amount of joints you make per buy and you will find out how much the average bag weighs in your area.
yeah, its all about your area, and the quality of the weed. some places it'll be $5/g, but in NJ its $20/g, for good bud/not the best.
