I know this thread is old but I just experienced this and I found this thread bc I googled gun smoke and asthma. I’m kind of newly diagnosed. We had a shooting class outdoors on Saturday. There were 13 of us that shot about 100 rounds each in a 7 hour period. That doesn’t sound like it would irritate my lungs but it absolutely did. I noticed a little bit of dizziness during the class but it was also 100 degrees (summer in Southeast Texas). About an hour after the class, I started feeling a heaviness in my lungs. Today is Monday and I am coughing up green hunks tinged with a little blood. I will have to rethink larger participant number classes next time.
