[|Human|] I am 27, I have smoked pot regulary since I was 18...for about 4 to 5, years I have been coughing up brown phlegm (primarily in the morning) which I knew was from smoking...I sleep in a room that has VERY VERY dry air in the winter time, and Ive had a bloody nose a month ago, and off and on since then Ive had a couple specs of blood in my mucus in the morning (maybe once every week or so)...well two days ago I coughed up two pinhead specs of blood in the morning after the phlegm, and TODAY I coughed up a what I would call microscopic spec of red that I can only assume was blood...could this be related to the dry air in my room, or should I be worried about something life-threating here....I have already made the decision to stop smoking
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. You are having hemoptysis (blood in sputum). And it is common in smokers. Common causes are lung infection (pneumonia or tuberculosis), bronchitis and lung cancer. So better to quit smoking as soon as possible. Consult pulmonologist and get done clinical examination of respiratory system, chest x-ray and PFT (Pulmonary Function Test). Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
