Severe asthma greatly enhances the risk of pulmonary embolism, particularly if chronic corticosteroids are used. - European Respiratory Journal ... 2.abstract

We are in a no win situation:
Environmental smoke can set off an allergic reaction (response) - continued exposure to a substance can lead to an allergy to it. The body itself sees that substance as a threat, the immune system reacts and attacks it because it carries toxins. When somebody eventually becomes allergic to smoke after continuous exposure to it, it is known as sensitization. Symptoms will appear when the individual's immune system starts producing antibodies to attack the substance - histamine is also produced, which causes inflammation.

Irritant-induced asthma - environmental smoke may cause a direct irritation in the lungs after exposure. This is not an allergic reaction - the condition is called reactive airways dysfunction syndrome (RADS). The bronchial tubes are sensitive to the irritants. Environmental smoke is known to cause RADS.
Corticosteroids are widly prescribed for asthma!
