CT scan can' say he/she is a smoker. But there are changes because of smoking which depends on whether you started smoking recently or long back Long-term cigarette smoking is associated with subclinical increases in wall thickness of sub-segmental airways whereas current smoking is associated with narrower airway lumen diameters. Smoking may contribute to airway wall thickening prior to the development of overt chronic obstructive pulmonary disease.
