Good point , but, as the thread began in a "pub" thread, it has stayed there.
I was a heavy smoker when younger, but stopped in March 1993. I cannot speak for all, but anything that is hopefully improving the quality of air we breath,then I am all for it!
My mates two girls make him stand outside their homes, when he has a puff on his pipe. Its all about choice IMHO. Many Wetherspoon pubs have a outside smoking area.
