"streets"? Are you seriously suggesting second hand smoke is a

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.

Curiously my son's asthma improved once he started spending time in
smoky pubs...
