Vaping is the act of inhaling an aerosol created by an e-cigarette or similar device. The term "vaping" misleads the user into thinking they are inhaling a vapor and something potentially safe or at least harmless. This is just one reason why the NFHS, with support from the Office of the U.S. Surgeon General, has created Understanding Vaping and E-cigarettes. This course helps dispel such misconceptions and highlights specific risks such as nicotine addiction for youth who try vaping and e-cigarettes.
