[|Human|] If I smoke about a ounce of weed with 3-5 people a day and use a full pack of smokes for that ounce a day what could happen to my lungs? I ve been doing this for about 4 years everyday and for the past two years I ve spat up quarter or toonie sized chunks of pitch black.. What are those?
[|AI|]  Thanks for your question on Chat Doctor. Smoking weed is not good for health. It can damage lungs in several ways. Possible damage in the form of1. Obstructive airway disease2. Restrictive airway disease3. Decrease immunity and makes patient vulnerable to infection. 4. Malignancy. 5. Pulmonary embolism. 6. Pulmonary edema secondary to smoking associated heart failure. So better to quit this habit. As it will only harm you. I advise you to consult pulmonologist and get done chest x-ray and PFT (PULMONARY FUNCTION TEST) to rule out above possible complications.
