Personal preference does come into it. I rather like the smell of certain kinds of smoke, but cannabis has this very strange sweetness which I find unpleasant. Smells certainly don't correlate with safety though; I like the scent of white spirit!

They really ought to have two smoking areas on each railway platform, one on either end, and make it compulsory for smokers to use whichever one would carry the smoke away from other users on a given day. Or, have a smoking shelter with a tall chimney to take it away more effectively vertically.
