I load a pipe on my coffee break in the morning, then smoke that for 10-15 minutes, then again at lunch time. At the end of the day if there's anything left I'll smoke it on the way home. I would say I average a bowl a day and maybe three a day on the weekend depending on weather (lately with this cold snap I'm lucky if I get one bowl in). In the summer I smoke more as it's more convenient. I will agree with whoever said it also depends on what you smoke. If I know I'm going to be smoking more I'll typically smoke mostly OTC's like Carter Hall as the nicotine is negligible in those blends. Then maybe at the end of the day I'll treat myself to something premium like SG Best Brown Flake or Capstan.
