Tell me, why is it that while cigarette smoking has been declining steadily over the years, allergies and asthma seem to be on the rise?

Your question is based on the false premis that smoking is the only thing that causes asthma & allergies. It is not. There are many enviromental things that cause allergic reactions including asthma. Also food chemicals & additives are often to blame. As an example, some people are allergic to corn.

Next time you are in a grocery store read a few labels, see how many products contain corn flour, corn starch, corn syrup & corn oil. This was not the case a few years ago.
Tobacco smoke is a problem for some sensitive people but hardly the only problem.
