Your assumption in #2 is incorrect. What actually happens often is the doctor doesn't know what to prescribe the patient and the patients quality of life suffers. As well as stated in my article, one of those alternative treatments "For another type of asthma treatment, long-acting bronchodilators, blacks are 4 times more likely than whites to die or experience serious complications when using them."

And that's not the only one.
