I generally smoke one bowl each evening, and that's about it for smoking. (I also eat two brownies a day usually.) So, about .7 grams per bowl comes out to maybe 20 grams a month? Hmm, maybe my bowls are smaller than .7, because an ounce usually lasts me two months these days, if not longer (not counting what I eat). That's smoking only premium stuff; I used to smoke more when I got mids, because it took more to reach the same state. Good stuff definitely lasts me waaaaay longer than lower quality stuff.
