• ✓. Must be willing to use the assigned IP and only the assigned flavor as their exclusive source of ENDS use for the full duration of the 9-day ambulatory period. Use of other non-ENDS tobacco- or nicotine-containing products will be permitted during the ambulatory period.
• ✓. Must have familiarity with modern electronic devices such as an IOS/Android smart phone or tablet computer ("tablet") and be willing to be provided with an electronic device, that allows for both Bluetooth connectivity and internet connectivity.
