Pack years is a term that can be used to measure how many cigarettes someone has smoked over a period of time. If you smoked 1 pack per day for a whole year that is considered 1 pack year, or if you smoked two packs per day for half a year that is also equal to 1 pack year.
20 pack years means someone has smoked 2 packs per day for 10 years, or 1 pack per day for 20 years, and so on. Essentially, someone who has smoked as many cigarettes as the number of days there are in 20 years would have a pack year value of 20.
Most of the time heavy smoking is considered to be one pack per day.
No, if you have a high pack year value it means you are smoking a lot.
