I smoked since 1971, 9 years old, and never had a day without since then! The past 15 years I was buying 2/3 packs of 24 Royals every day so smoking 48 to 55 a day. I started vaping in 2012 but dual fuelled it for nearly 2 years. I've now been off the smoking for 15 months so I should have a few things improve.
Taste and Smell haven't improved a lot but I have some Paralysis on one side and it affects my face and tongue, I assume the receptors are a bit buggered there. Throat wise I'm not happy. Around a year or so now there's been a growth in my epiglottis, I'm waiting a biopsy to be sure if it's cancer or not. The paralysis effects my sinus and means I can only "Mouth Breathe" with a nostril that wont open to breathe in, so I get a really distressing dry mouth and throat all the time,have to carry liquid everywhere I go for that.
Lungs? I am asthmatic and the last lung function test I did was as good as a Non-Smoker, I AM a non smoker, Dammit!
I have a lot of, serious, Health problems dating back from 1996, Coma with brain injuries, and I am certain that a few things I hoped would improve are being held off by the other problems.
The state I was in and getting deeper into would have seen me either Dead by now or, at least,wishing I was Dead.
