Lower respiratory infection caused by smoking too many cigarettes, breath smells like metal, can i use a humidifer or should i stay away fr moisture?

Quit smoking instead: I do not think that humidifier is going to hurt but the bigger problem here is the harm that you are getting everyday by smoking. Your lungs are complaining!

Humidifier: Probably ineffective. I don't have to tell you this, what you need to do is quit smoking. Your body is sending up red flags. Please immediately be evaluated by your General Physician or preferably a specialist Pulmonologist or a specialist Oncologist. To be frank, you are killing yourself.
