The force of delivery is less so the delivery of medicine into an obstructed breathing passage is not the same. There are peanut and corn-based components as well. These are asthma triggers for some. Drug companies could care less because they get a new patent and can charge premium price. A portable nebulizer may be the only recourse for some. This is lunacy.
Maybe I should get enough to last me for a couple years. My asthma is extremely, extremely minor and only really flares up with illness.
