Hi, my name is Eric. I am 20 years old, 5'9 and 100lbs. I am very skinny and tall. I'm in the hospital right now for my first lung collapse at 30%. I've been smoking medical marijuana for about 2 years everyday of my life. About 2 grams at the least and about a 7 grams the most in one day. It is a lot but I don't feel like I'm over doing it since famous people (rappers) smoke way more heavy than me. Anyway that being said, is marijuana the cause of it and must I quit? I really do need the medical marijuana for my extreme lack of appetite so I am really concerned about my situation. Please and thank you for your time.
