Quit ciggs 13 yrs ago. light med mj use. constant nasal drip. snorted mucus from nose into throat, maybe coughed too, not sure if i coughed. basically clearing throat mucus in morning. little bit of brown mucus one time. is brown mucus concerning?

Try to stop smoking: What is "light" marijuana smoking? Any at all is harmful -- mj smoke is just as bad for lung health as tobacco. Your symptoms suggest bronchial/lung irritation and damage from smoking. Discuss with your doctor: you need lung function testing and maybe a chest xray. There may be alternate treatments (cannabinoids or other) that would help whatever symptoms you are treating with mj.
