ENDS stands for electronic nicotine delivery systems.

According to the Consumer Advocates for Smoke-Free Alternatives Association (CASAA), the first e-cigarette-like product was submitted to the Food and Drug Administration (FDA) in 1998 for consideration as a drug delivery device. Despite the agency denying the application, it wasn’t long before e-cigarettes and other electronic nicotine delivery systems (ENDS) devices were lighting up international markets. By 2006, the first e-cigarette hit U.S. store shelves, and within a few years, ENDS found a permanent placement on c-stores’ back bars.
