Vape residue has been a topic of concern for many individuals, as it is often left behind on surfaces and in the air after vaping. While research on the long-term effects of inhaling vape residue is limited, there have been some examples that suggest it may be harmful to human health. For instance, one study found that vaping indoors led to higher levels of particulate matter in the air, which can cause respiratory issues. In addition, some chemicals commonly used in e-liquids have been linked to lung damage and other health problems. While more research is needed to fully understand the potential risks associated with vape residue exposure, it's important to take precautions such as proper ventilation and regular cleaning to minimize any potential harm.
