i was researching to see if marijuana can be helpful in cases of bronchitis. What i found was that emphysema can be caused by heavy smoking, and marijuana was worse than cigarettes, insofar as you inhaling all the smoke your lungs can take in and hold it in, repeatedly, damaging tissue in your lungs making it difficult to breath, im still researching, and havent found that marijuana has been proven to help bronchitis, i hope so, that way i can get my smoke on, and feel comfortable knowing its just for my health instead of making it a ritual or habit, i would just take it easy on the stuff, and hope my breathing improves, wouldnt it be better to get more oxygen into our bodies by improving our breathing, I always feel like im suffocating.
