Do the new asthma inhalers work as well as the old ones?

Yes, but they may take some getting used to.

For years, the propellant in inhalers was chlorofluorocarbon. The CFC helped push the active drug, such as albuterol, out of the canister and into the airways, making breathing easier for people with asthma. But CFCs damage the earth’s ozone layer and have therefore been eliminated from many products.
