So I have for pretty much three weeks, and I have taken care of myself and my body pretty well since I was diagnosed. But last night I was around a few friends at their house and the were smoking cannabis out of a tobacco paper a few times while I was there, but I did not partake in smoking but was sitting with them around second-hand smoke. There wasn t a window in the house open, and I was with them for 12 hours. I feel absolutely stupid now, for being around the smoke!! Will this worsen the pleurisy and should I go to the doctor and get checked back out again for further damage to my lungs? I thought if I couldnt feel the effects from being around the smoke it wouldnt affect the pleurisy, but man was I wrong at least I think?! PLEASE HELP!
