Wow, you really picked the wrong link to support your claim. The entire article is filled with statements that refute your claim, such as the following:

> Allergy-like symptoms can be caused by tobacco smoke, but most doctors believe that they are not reactions to the smoke.

> Rather, because tobacco products (especially cigarettes) are filled with many toxic ingredients and irritating chemicals, some people have a reaction to those specific substances. People who suffer from allergic rhinitis appear to be more sensitive to these chemicals than others.
