What do electronic nicotine delivery systems (ENDS) produce?

Electronic nicotine delivery systems (ENDS) produce a tobacco-containing aerosol that users inhale. These devices, such as e-cigarettes, work by heating a liquid that usually contains nicotine, flavorings, and other chemicals. This process generates an aerosol, commonly referred to as vapor, which users then inhale.

It's important to highlight that while the term "vapor" is often used, the aerosol produced by ENDS does contain tobacco-derived nicotine along with various other substances. This means that even though ENDS do not produce traditional tobacco smoke, the aerosol still incorporates components from tobacco, directly affecting the user's exposure to nicotine and other chemicals.

The other choices do not fully capture this essential aspect of what ENDS deliver. While they imply an absence of certain harmful substances found in traditional smoking, they misrepresent the nature of the aerosol being inhaled. Thus, the most accurate characterization of ENDS is that they produce a tobacco-containing aerosol.
