Inhalers Alternative ways to recycle Hazardous Waste Never Throw in the Trash Older inhalers contain chlorofluorocarbons (CFCs). CFCs can damage the ozone layer, so never throw them in the trash. Follow the disposal instructions on the inhaler’s label and dispose of as Household Hazardous Waste. Never Puncture or Burn Do not puncture the container or throw it into the fire because an inhaler is an aerosol product and could explode. Alternative Ways to Recycle Return Used Cartridges to the Pharmacy Some pharmacies and law enforcement offices are registered with the DEA as authorized drug collectors; you can drop-off used inhaler cartridges at these locations. Find a DEA-authorized disposal location.
