They’ve already done it. They phased out the inhalers that worked well for these awful things that barely deliver any medication, and cost through the roof.
These do gooders and their stupid climate nonsense will be the death of us. It’s eighty where I live today, with record cold everywhere else, but they are still determined to grease us up anyway.
They still deliver the exact same dose of medicine.
The propellant has no medicinal value whatsoever.
So unless you think CFC’s have some sort of medicinal value that made Advair and Salbutamol work, it’s all in your head.
I use both and they work just the same as they always did. The inhalers still contain and deliver the exact same metered doses of medication
