I found this conversation after I typed in my URL “smell cigarette smoke”. What really caught my attention was seeing that you are also taking gabapentin! I have been taking it for about 20 months. I am now only taking half (600mg) what I was for the first year. But the cig smell started about three days ago and it is getting more often and stronger! Obviously no one else can smell a thing so it is just me. I too am a former smoker but it’s been 15 years or more! I have already had covid-19 and it took my sense of taste and smell but that was months ago and my senses returned slowly but surely. I just think it is so odd to have this hit out of the blue. And it is just so ODD to smell cigs!! Why not cotton candy or gardenias??
