If you vape at home, you may have wondered whether it affects the people around you. While vaping is often seen as cleaner and less harmful than smoking, it still releases vapour into the air. So does this have an effect on other people in the same room, or is it safe to vape indoors?
This guide explores what we currently know about second-hand vapour, how it compares to smoke, and what to consider if you live with children, family members or flatmates.
Is second-hand vapour harmful?
Vape vapour is not the same as cigarette smoke. It does not contain tar or carbon monoxide, and it breaks down more quickly in the air. That said, it is not just water vapour. It contains traces of nicotine, flavourings and other substances found in the e-liquid.
While the levels of exposure are much lower than with second-hand smoke, there is still some concern about prolonged or regular exposure in enclosed spaces. In particular, children, pregnant women, pets and people with asthma may be more sensitive to the ingredients in vapour.
Can people in the same room be affected?
In a well-ventilated room, the effect of vaping on others is usually minimal. Most of the vapour dissipates within a few seconds and leaves behind only a light smell, depending on the flavour used. However, in smaller rooms or if vaping is frequent, the concentration of vapour may build up over time.
People who live in the house may notice:
-
A slight haze in the air after heavy vaping
-
A lingering flavour or scent in the room
-
Irritation to the throat or lungs if they have existing conditions
-
Buildup on surfaces if windows are rarely opened
Devices like the Lost Mary BM6000 produce less vapour than larger mods, but even compact pod systems can leave a trace in small, unventilated spaces.
What about children and pets?
Children and pets are more sensitive to their environment. Even low levels of airborne substances can affect their breathing, especially if they have allergies, asthma or other respiratory issues.
Most health advice in the UK suggests not vaping around children or in homes where babies or young children spend a lot of time. Pets, particularly birds and cats, can also be sensitive to vapour ingredients or strong smells.
If you do vape indoors, try to do so away from shared living areas and always ventilate the space afterwards.
Does vaping indoors leave residue?
Yes, to a small degree. While not as visible as smoke stains, vapour can still leave a fine coating on windows, walls, furniture and electronics over time. Sweet or sticky flavours may be more likely to leave a residue, especially with frequent use.
You may not notice this right away, but over time, it can create a thin film that dulls surfaces or causes smells to linger in fabrics.
How to reduce the impact on others
If you want to be considerate of others while vaping indoors, here are a few tips:
-
Vape near an open window or extractor fan
-
Avoid vaping in shared bedrooms or small enclosed spaces
-
Choose lighter or less intrusive flavours
-
Take shorter puffs to reduce cloud size
-
Use air purifiers or indoor plants to help clean the air
-
Rinse your mouth if you are vaping just before speaking closely with others
These small steps can make a big difference, especially if you live with non-vapers or children.
What about guests or flatmates?
Even if vaping is allowed in your home, it is worth checking with guests or housemates how they feel about it. Some people may be sensitive to the smell or just prefer not to be around vapour. Respecting shared space helps avoid tension and keeps everyone comfortable.
If you share your home with someone who does not vape, consider limiting your vaping to one designated area and using ventilation to reduce lingering vapour in other rooms.

Final thoughts
Vaping indoors is much less harmful than smoking, but it can still affect others in small ways. Second-hand vapour is not risk-free, especially for children, pets or those with breathing problems. It is important to vape with care, ventilate your space and be considerate of who you live with.
If you are switching flavours or adjusting your routine, the Lost Mary BM6000 collection offers a wide range of options with smooth delivery and compact design.
