Wow. It was such a relief to find that there was a response to my google of "abnormal smelling cigarettes". I have been experiencing this for months now. I am grateful for everyone sharing their experiences and suggestions. I am going to go through this board carefully.
At first it started out as a smell at work. It smelled as though someone's clothing might have smoke on them. I asked everyone around me and noone said they smelled smoke, including one woman who told me if there were any smokers in the room, she would know.
I have never been particularly affected by cigarette smoke. Always willing to sit in the "smoking" section of a restaurant if it cut my wait down.
I constantly ask people around me "Do you smell smoke?" Mostly the answer is no. Following up on someone's post, I went to my husband and asked him to smell my exhalation from my nose. He is a very skeptical man, so imagine my surprise when he asked me to do it twice. He says he smells something faint. Maybe some fungal or bacterial infection which puts out this odor and hence the smell?
I am almost delighted to read all these posts because the first thought I had was at worst a brain tumor and at best olfactory nerve damage. I hate to get delight at other people's discomfort, but it makes me feel not so crazy OR ready to die from a brain tumor.
Anyway, thanks for posting all this information. Helps to know I am not alone.
