Can I just say, as an ex smoker, I am not rabidly anti all things fumitorial. Although they do say that we ex smokers are the worst when it comes to dissing those who still indulge in the weed.
I will only say this, my life has improved tremendously since I stopped smoking, particularly my sense of smell, and of course along with that my sense of taste has improved too.
When smokers waft past me in the street and I can smell the smoke off their clothing, I wonder if I smelled like that to other people. I suppose I must have, but I was blind [anosmic?] to it.
So while I defend your right to smoke, I encourage you to give it up too.
Then when you're cured, go down the pub and have several pints, and a sing song :)
