Still working but something occurred to me while I was rolling up some thinking-leaves. I just want to place it here for opinions and will probably come back to it in detail later.
How many anti-smokers enjoy Parma ham or smoked salmon or kippers? And have they grasped how those things are made?
When (if) they do, will they realise that the risk of third hand smoke is only comparable to those things if they saturate their sofa with smoke and then eat it?
It's also given me an idea for a meal - Parma ham, smoked salmon, the Ardbeg and a cigar. It ALL tastes of SMOKE! Oh, the Righteous will burst their brains trying to take it in.
