As an occasional pipe smoker, I can tell you that 180g/day is nigh-on impossible. A "bowl" (the unit you put in the pipe at once) is 1g - 1.5g, or roughly the same amount as in a single cigarette. So, that's 120 - 180 bowls per day. With an unfiltered pipe you would incinerate your tongue in a day smoking that much. Longer stems might help, but that is still a shitload of tobacco.
