Flavored electronic nicotine delivery system product use among adults in New York State post-statewide restriction implementation.

In May 2020, New York State restricted the sale of flavored e-liquids, excluding tobacco flavor. We conducted a Web-based survey to assess support and changes in use behavior between July and October 2020 (n = 946), with a follow-up between April and June 2021 (n = 542). Most electronic nicotine delivery system (ENDS) users (n = 82/55) continued to use, with 39%/33% reporting continuing to purchase flavored e-liquids, 20%/32% reporting using tobacco flavor, 5%/6% reporting quitting ENDS and smoking cigarettes, and 8%/3% reporting quitting ENDS and not smoking cigarettes. In 2020, 65% of non-users, 53% of cigarette users, 34% of cigarette/ENDS users, and 18% of ENDS users supported this policy restriction on e-liquids. Similar results were observed in 2021. Many ENDS users continued purchasing flavored e-liquids, suggesting that compliance with the policy can be improved. Cigarette smoking did not appear to increase. Continued evaluation of how restrictions on sales of products influence use is critical to understanding the long-term impact on behavior.
