Vaping in a room can leave a slight odour, although less pungent than the harshness of cigarette smoke. Vaping vaporises e-liquid at a lower temperature than cigarettes burn, resulting in a smell that, while less intense, does not linger as traditional cigarette smoke does.

The use of e-cigs in indoor environments leads to high levels of fine and ultrafine particles similar to tobacco cigarettes (t-cigs).

The enjoyable pastime of vaping can leave an unwelcome lingering odor in indoor spaces.

While their scents generally dissipate quicker than tobacco or marijuana smoke, most vapes leave a distinctive smell behind. If you suspect someone in your home has vaped recently, smell their clothing or the area they were standing to try and catch a whiff.
