Hey, I've Come Down With A Chest Infection. I Smoke

Hey, I've come down with a chest infection. I smoke marijuana at least three times a day, which I understand bring a bunch of health risks. I suffer from several mental illnesses with PTSD being my most troublesome one. The weed I smoke keeps me from having flashbacks, gives me my appetite back, and allows me to stay asleep. Although I am aware my habit has most likely caused my infection, I want to know the effects of smoking weed while sick and if I really ought to stop to get myself back to health.
