The experience of inhaling from a vaping device that has overheated or run out of e-liquid results in an unpleasant and potentially harmful event. This occurs when the heating element, or coil, attempts to vaporize material that is no longer readily available or has become degraded due to excessive heat. The consequence is the production of a harsh, acrid vapor that is markedly different from the intended flavor and consistency of the e-liquid. An example of this is tasting a metallic or chemical flavor instead of the expected fruit or dessert profile.
Understanding this phenomenon is important for both users and manufacturers of vaping products. Awareness allows users to avoid negative experiences and potential health risks. For manufacturers, it highlights the necessity of developing devices that prevent overheating and efficiently manage e-liquid consumption. Historically, the evolution of vaping technology has been driven, in part, by the need to mitigate this issue and enhance the overall user experience. Addressing this prevents discomfort, safeguards respiratory health, and contributes to the responsible use of vaping technology.
