I've been reading things about secondhand smoke that really surprised me. I had no idea exposure to other people's smoking could cause things like blood sugar problems and pancreatic cancer. I'm wondering what else it could cause! I was born to two parents who smoked before it was known to be harmful. I'm sure I inhaled in utero and in infancy, and beyond. I also smoked myself from age 14 to 28. How about the rest of you? Has secondhand smoke been part of your life, particularly your early life? And could it cause flares today?
