These “electronic nicotine delivery systems” or ENDS are not approved by the FDA to help people quit smoking. There is not enough scientific evidence to say that they are safe or effective. Fortunately, for smokers who want to quit, there are approved medications for this use, as well as behavioral counseling — all of which are considered effective and safe. We advise people who are interested in an ENDS product to consider using the FDA-approved NRT, Nicotrol inhaler, which allows you to puff on a plastic piece to get a reliable dose of safe nicotine vapor. The Nicotrol inhaler can be used in all indoor settings because there is no combustion or heat.
