0 or not even 1 because no good
Some people can go through 2 to 3 packs of cigarettes a day. Some might do more, but what I seen for my own eyes, it was 2 to 3 packs.
I personally smoke about a pack a day.. Some people are chain smokers & will smoke 2 or 3 packs a day.
I smoke around a half a pack a day. But I live in washinton state and there talking about adding two dollar tax to a pack. I really hope I can quit because I can't afford it now.
