the short answer is yes. each asthma patient responds differently to "first-hand smoke" and "second-hand smoke". much depends on the severity of the individual's asthma disease progression other breathing compromises such as copd the overall health of the patient the age of the asthma patient and the degree of smoking being done in the home that is being visited. an attack of breathing difficulty can occur even hours after leaving the offending house. some recent studies have begun to evaluate the danger of "third-hand smoke". this is another form of environmental smoke. it is the residue of tobacco smoking that is found on the clothing or hair and skin of a smoker and on the furniture or in the car where people have been using tobacco products. studies have also shown that the smoke residue from 2nd and 3rd hand smoke is even more dangerous than that of 1st hand smoke. this is because more toxic chemicals are received by the victim of environmental smoke then are received by the smoker themselves. asthma patients sensitive to a smoker's poor home air quality should consider that location "out of bounds for visitation". explain to the smoker that you have asthma and cannot visit their home due to your lung disease. also explain to them the definition of "third-hand-smoke". sure some folks will balk and claim that third-hand-smoke does not exist. but responsible family members and true friends will understand your lung heath needs and concerns.
can asthma be triggered hours later after leaving a smokers house using air cleaners and no direct smoking
