Am i affected by second hand smoke?

i was wondering if i am affected by second hand smoke. my dads smoked for a long time, before i was born i think, and he quit smoking about 4 years ago. he smoked a lot when i was little, but it was never inside the house, always out in the backyard, but i know i breathed in a lot. i am now a freshman in high school. am i still affected by second hand smoke? i just got bronchitis a couple of weeks ago and my lungs have never been able to expand all the way. i was wondering if these problems are caused by second hand smoke?
