I can't see the original poster of this, as my reader dumps read posts, but

"streets"? Are you seriously suggesting second hand smoke is a
problem in the open air?

I was born with asthma and foolishly took up smoking at an age of about
17. Since giving up the weed and indeed before, I have had a reaction
whenever I walk past someone smoking in public. It literally takes my
breath away, as does the exhaust from most diesel engines.
