If your doctor is of the opinion that any asthma diagnosis is likely to have been incorrect (and it is understood that asthma is over diagnosed), and he is willing to provide this in writing, then your case MIGHT be reviewed by the OASC Med Board. However, this is very VERY rare, more so if there has been multiple prescriptions. Remember, for every one candidate with a potential asthma issue, there will be literally hundreds without so why should they take the risk? (Please note that actual use of an inhaler is irrelevant, it's the fact that the doctor saw fit to prescribe it which counts. I hear almost daily potential candidates claim they had an inhaler issued every few months for the past 10 years yet never actually used it.)
