Reaction: Unsure of what is the likely chemical trigger but you should see an allergist and get treated.

A Condition called: Constrictive bronchiolitis obliterans, or "popcorn lung, " due to breathing in a chemical (diacetyl) that gives artificial butter its flavoring in microwavable-butter popcorn, has been known to cause the symptoms you describe. Hypersensitivity to other allergens may be an issue, too. Consulting with a pulmonologist (lung specialist) is highly advised.

Asthma: Sounds like you may have asthma and cigarette smoke is one of your triggers. Best to avoid it if possible.
