When compared to traditional cigarette smoke, vape vapors disperse and evaporate much faster. This is primarily due to the fact that they are less dense and have smaller particles. However, they can still linger for some time depending on various factors.
For example, the size of the room and how well ventilated it is will play a big role in how long the vapor clouds remain. A bigger room with plenty of airflow will allow the vapor to disperse and move much more quickly than a smaller space. Similarly, the vapor’s longevity can also be affected by how humid it is.
The evaporation of the vapor clouds can also be affected by the VG/PG ratio of your favorite eliquid. Vegetable glycerin has more mass than propylene glycol, and thus, it takes longer for it to evaporate. This is why a blend with high VG will create thicker and more substantial clouds that can linger for a bit longer than one with lower VG.
Another factor is the amount of vapor that settles on surfaces like curtains and furniture. Regularly wiping down any surfaces that might be exposed to vapor is helpful as it can help reduce the amount of lingering odor.
All in all, the short answer to how long does vape smoke stay in the air is that it can linger for a few seconds or minutes at most. The key is to always be mindful and ensure you’re vaping in a properly ventilated area and taking steps to minimize the length of time it will linger.
