Ban on CFC Inhalers

The FDA in compliance with Montreal protocol has banned the use of life saving CFC propellant asthma inhalers in order to save the ozone layer from depletion even though it has been acknowledged earlier that these inhalers do not perceptibly harm the ozone layer.Tremendous efforts have been made to reduce the CFC emissions in U.S. to less than 1%. However to eliminate this tiny amount of CFC from the environment,millions of Asthama patients have recently been forced to use new HFA(Hydrofluroalkane) inhalers. Transition has not been seamless. the main reasons being since HFA is not avilable in its generic form,they are more expensive than CFC inhalers.Some people believe that CFC inhalers were more powerful than HFA inhalers.But many doctors disagree saying that HFA is as good ,if not better than its CFC cousin.HFA and CFC inhalers are same in shape and size. The main difference? They have slightly different smell and taste and HFA mist is little less forceful and warmer coming out of inhaler.
