Former smokers are especially concerned about vaping indoors, since vaping indoors can cause permanent staining and hard-to-remove smells, in addition to concentrating second-hand smoke. So what happens when you vape indoors?
Staining from analog cigarettes can be attributed to the tar incorporated into tobacco products. When tobacco is combusted, this tar is released in the smoke, and over time will accumulate on surfaces, permanently staining walls, windows, cabinets, linens and other household products.
There is no tar contained in e-liquid, and so vaping indoors does not create these issues. However, vegetable glycerin and propylene glycol can visibly collect on windows and other surfaces when vaping in confined spaces, but can be easily removed with regular cleaning products.
Smoking indoors is known to create a foul, lingering smell that sticks to any fabric or porous surface.
Vaping flavoured e-liquid may produce some light smells, but these are often much more subtle and pleasant. In a confined area, there may be some residual smell. However, these can be eliminated by airing out the space and with regular cleaning.
Second-hand smoke is created from the dangerous chemicals released in burning tobacco. This includes hydrogen cyanide, carbon monoxide, ammonia and arsenic. By smoking indoors, you expose yourself and others to concentrated levels of these chemicals over long periods of time, which can ultimately result in cancer and other illnesses.
Since vaping does not emit these types of chemicals, there isn’t as much worry about using your e-cigarette indoors. Vaping may, however, create a bit of a stuffiness to a confined space, but this can be combated by airing out the space regularly.
