It's even worse than you imagined:

Manufacturers use chlorofluorocarbons, or CFCs, as propellants (spray) in these inhalers to move the medicine out of the inhaler so patients can breathe the medicine into their lungs.

The United States signed an international agreement, called the Montreal Protocol on Substances that Deplete the Ozone Layer along with many other countries. These countries promised to make it illegal to make or sell substances that decrease the ozone layer, including CFCs, after certain dates.

Is that why they are trying to take my Symbicort away from me?

Last refill I got some stupid purple disk that left my mouth full of powder. After trying the disk for a week and popping a rib from coughing I went back to my doctor and got him to tell the pharmacy company that I needed the real stuff.
