How long do you have to be around smoke to get lung cancer?

Question by Pureinfamy: How long do you have to be around smoke to get lung cancer?
Yeah….how long do you have to “second hand” smoke before you develop lung cancer? I heard it can happen if you’re around a smoker at least one time. And what if you’re also twenty years old? When will the lung cancer be developed then? Is there still a chance of getting lung cancer if you’re riding in the car with all the windows open? Or if you’re in an open space?

Answer by TIMOTHY
If you actually smoke it could take 30 to 40 years to develop lung cancer second hand smoke 40 to 80 years if ever. As Yoda would say be afraid not.
