I usually smoke in the evenings, either a pipe or a cigar. On pipe nights it's usually 2 or 3 bowls. Varies with bowl size though - if I'm smoking my mini-meer, it might be 4 or 5.

A BOTL at work, who also goes both ways, lamented that when he smokes a pipe, he "overdoes it" by smoking 2 or 3 bowls. I reminded him that a cigar has enough tobacco for several bowls of pipe tobacco. He feels better now
