My lungs are very sore and often cough up blood and black, ive smoked marijuan in bongs for three years aswell as cugarettes im 17. There so sore?

Cough. Depending on the length of symptoms and whether associated with fever chills weightloss you will need to make sure you don't have pneumonia or some other lung infection. I would get to the doctor for a chest X-ray , lab work and possibly some antibiotics for starters.
