The enjoyable pastime of vaping can leave an unwelcome lingering odor in indoor spaces. Unlike cigarettes that burn and give off harsh smoke, vaping vaporizes e-liquid at a lower temperature, producing a less pungent yet still persistent smell.

They look like white clouds of water vapor or smoke and vary in quantity by the type of vape device. If you see a greasy film on the windshield of your teen's car, this could be residue from vape clouds.
