Given that I, personally, share this problem (though smoke is about the only thing that triggers it, rather than the host of things than can set off more severe athsma) I second the opinion that the day all burning-type tobacco products are banned will be a good day. Seriously, inject yourself with strychnine for all I care, but don't go leaving a cloud that can set me off two minutes after you've gone past.
