I might smoke between 5 and fifteen grams a day. Depends if it's a blunt day or a spliff day. Most of my spliffs I roll'em up with exactly .5 grams. As soon as I wake up, I chief on a spliff, and that one joint will keep me nearly painless for, I'd say, about three hours. Then every three hours, I'll smoke a joint (don't really have to keep track, I smoke one whenever pain starts to get annoying) I keep a pack of papes on me and tin of 10 grams of some decent bud on me most of the time. So, if I wake up at 6 in the morning, and go to bed at 10 PM, then that's 6 joints, but then I smoke one when I go sleep, so that's seven. That is 3.5 grams a day, or an eighth. Some days I might not smoke at all, then at the end of the day I'm proud of myself because I didn't have to.

PS: My joints aren't EXACT all the time, but pretty damn close...
