How can you prevent emphysema?

Answer:
The best way is to reduce smoking as smokers chances to get emphysema is much higher than the non-smokers. However, in certain people, it is due to genetic reason (ie: alpha-1-antitrypsin deficiency) which means not much thing can be done to prevent it but some intervention is still possible to reduce the symptoms.
