Re: How much Gram per session ?
For me it depends on the bowl. A lot of vendors tell you how much tobacco their bowls hold, so I fill it up which ends up being pretty close to that number. I usually smoke with friends so we take a hit about every few seconds. If the tobacco is of good quality we can go through 4-6 coals (using 2-3 at a time, depending on how much heat they put out).
Gotta love them clouds
