Yes a person can get COPD even if they never smoked.
Usually a person develops COPD without smoking when they've been around others smoking which is known as second hand smoke.
If you don't smoke you should avoid any places or avoid being near others that smoke and you should be fine.
Although it's still possible to develop COPD even while not around smokers but you have a less chance of getting COPD if you stay away from smoking and second hand smoke.
