The association of asthma development and smoking has been extensively
studied for conventional cigarettes.34 Extensive
hazard to respiratory system have been recently reported in multiple
studies.35-38 A study evaluated the impact of
electronic cigarettes and heated tobacco products on asthma and allergic
rhinitis (AR). The survey in Korean middle and high school students
could not determine these tobacco products to be a risk factor on their
own, however, in combination with conventional cigarettes they could
worsen asthma and AR status of children.39
