The amount one smokes is often measured in a unit called the pack*year
A pack year is the number of packs you smoke a day * the number of years you smoke. Most studies which show tobacco having a deleterious effect on the body happen after a 10 pack*year history of smoking. This can be 1 pack a day for 10 years, 2 packs a day for 5 years and so on. Believe it or not, I've seen a person who was smoking 5 packs of cigarettes a day!!!
Anyway, so you having smoked 3/24ths of a pack off and on for 10 years is almost a negligible amount of smokes for a risk for cigarette induced lung cancer.
