Every smoker is producing 20 to 40 pieces of litter per day -- every butt that gets tossed.

20 to 40 smokes every day is very heavy smoking, I'd guess most smoker aren't at that level

It's somewhat heavy, but not extraordinarily so. The average smoker consumes just under a pack a day. A heavy smoker might go through two or three packs a day.
