There is no way that inhalers are addictive.
You have been prescribed one because you need it to treat your asthma.
Now you can choose between oral medicines which are slow to act, first go to your stomach, get absorbed by blood, go to
liver where it is digested(metabolised) then come back yo blood and then spread all over the body vs a very small quantity of medicine in the form of vapour going into the lung directly and helping you get better.
I have no experience with other forms of medicine.
