Presence of Nicotine Warning Statement on US Electronic Nicotine Delivery Systems (ENDS) Advertisements 6 Months Before and After the August 10, 2018 Effective Date.

Results from this study provide initial insights into the extent to which required nicotine warning statements appear in ENDS ads in the study sample across traditional (eg, magazines, television, radio) and digital (eg, online/mobile ads) advertising mediums. Following the August 10, 2018, effective date, we observed a substantial increase in the presence of the required FDA warning statement on the ENDS ads in this sample. However, a notable number of ads in the study lacked the required warning and warnings did not always include the required formatting displays.
