I smoke at least 3 regular size sticks daily, sometimes up to 5 depending on what's going on. That's not counting a few quality cigarillos on the way to work and on smoke breaks.
Of course, the bulk are bundle sticks, with a few quality cigars in the evenings. I also favor robustos or corona size sticks, so it's not really hard to do 20 to 25 per week.
I went so far as to screen in my back porch and put in plexiglass storm windows and a radiant heater to stay somewhat warm in the cold Michigan winters! Next to come is an air scrubber and exhaust system!
