Hi,
Something I've noticed from time to time and thought I'd ask others about.....
Every once in awhile I will get a (small) whiff of cigarette smoke. At first I thought that it might be a smoker walking by, a jacket or sweater I've not not washed. Over time, though I ruled these out. I was then thinking that it might be in my head....
Then I remembered reading on the web that this can be something coming up from my lungs. I tried to find the reference again but cannot.
Figured I'd post and see what other folks knew.
Any thoughts?
Is it in my head?
