not that i know of it should show fluid build up an inflammation due to the virus
i've smoked chronic for over 15 years and had caught pneumonia real bad and had inflammatory bronchitis at the same time it was real bad i told my doctor
i don't smoke anything and i also do not smoke cigs either nothing was mentioned by doctor or any staff member

on the other hand your an adult now time to let your nuts drop explain it to him and give the reason why and assure your family that you'll quit if and when you feel the tie is right i highly doubt they'll disown you for your adult decision
emphasize that alcohol i way more dangerous and highly addictive and it makes you smell and fat and cigs cause cancer the very disease that cannabis helps fight
