There's actually very few documented case of true perfume allergies, but a lot of people will complain of such. In many cases, they simply find the fragrance unpleasant, or it might be acting as an irritant.(As opposed to an allergen.)

Some 'sufferers' complain that the issue is a lot like cigarette smoke. No, it isn't. Not at all. The mechanism is different.

There are certain drugs that depress the sense of smell, or occasionally change it. IE Nexium.

Thinking of my familys' lifestyle, and our religious practices, it would be very hard for us to comply with such a total ban on fragrance. Would we have to bathe before going to a hospital in an emergency? Before we ran to the store?

I would love - LOVE - to see an extensive study documenting these adverse affects using something to temporarily decrease the sense of smell. I'd highly suspect that a lot -most- of the 'allergy sufferers' would fail to react to the presence of scent.

To ask the general population to divest themselves of one of the pleasures of our senses, to me, is quite outrageous.

No doubt that people suffer. Once I had a flight - nonstop - from Atlanta to San Diego in which I was in front of a kimchee eating maniac. I was sick the whole trip, but I was NOT allergic to the kimchee. I just didn't LIKE it.
