Banned CFC-driven Inhalers

In August 2008, Scientific American did a story about a federal ban on ozone-depleting chlorofluorocarbons (CFCs) to conform with the Clean Air Act. The albuterol inhalers without any CFCs cost three times more than generic inhalers that use CFCs. The CFCs from inhalers have an insignificant impact on the Ozone Layer but raising the cost of a $15 inhaler to $45 is a significant burden. I tried searching online but kept finding articles from last year. Does anyone know if this moronic switch has been enforced?
