hi guys I'm new to vaping. I am three weeks without a cigarette. I am 20 years old. I am worried I have copd I have constant mucus in my Throat 24 / 7 I spit up in the morning and so on during the day. That's a symptom of copd. I'm kind of scared about it honestly. I just went for a x ray on my my head. To check my sinus and stuff like that because they think it might be allergies but what if it isn't. Does anyone on here have copd? Does this sound like anything familiar?
