Awareness and beliefs about FDA e-cigarette regulation in the premarket application review era.

Introduction: In March 2022, FDA granted its first marketing orders for e-cigarettes. Few studies have assessed awareness of FDA e-cigarette regulation and authorization in the era of premarket review. This study describes prevalence of awareness as well as beliefs about regulation among adults who smoke and youth.

Methods: We conducted a cross-sectional, nationally representative online survey of 866 adults who currently smoke cigarettes and 859 youth (ages 15-20) in June 2022 using Ipsos KnowledgePanel. Population prevalence of regulatory awareness and beliefs are reported. Pearson χ and multivariable logistic regressions were conducted to assess dependent and independent associations with demographic and tobacco use characteristics.

Results: Awareness that FDA regulates e-cigarettes was low among adults who smoke (25.4 %) and youth (18.5 %). Awareness that FDA authorizes e-cigarettes was also low among adults who smoke (10.8 %) and youth (12.7 %). Agreement with both positive and negative beliefs regarding FDA e-cigarette regulation was below 50 %. Current e-cigarette use was significantly associated with agreeing that regulation: makes e-cigarettes safer (adult aOR: 2.90, youth aOR: 2.51), helps prevent youth initiation (adult aOR 1.92), takes away freedom to choose to use e-cigarettes (adult aOR: 3.02, youth aOR: 2.58), and limits types of e-cigarettes available (adult aOR: 2.22, youth aOR: 2.49).

Discussion: There is low awareness of FDA e-cigarette regulation and authorization and relatively low agreement with positive beliefs about e-cigarette regulation. Further study is needed to assess how the changing regulatory environment impacts product perceptions, intentions, and behaviors.
