I decided to quit smoking 7 months ago using nicotine patches to help. I am 32 years old and smoked for 16 years, so half my life before this round of quit. After the first few weeks I noticed that I was coughing up phlegm that had gray/black in it. I assumed this might be normal after quitting smoking but I'm also a little worried. I have an appointment this week to get checked out, but I'm wondering if anyone else has experienced this?
