It's also worth mentioning that albuterol and similar inhalers used to be an exception to the prohibitions on CFCs (these inhalers an't used in large enough volume to do significant ozone damage), but due to lobbying from the companies that made them, they no longer are.
Why would a company lobby to outlaw its current product? Well, they had patents on "improved" CFC-free versions, allowing them to exclude new entrants from the market.
