I use e-cigarettes (i.e., vape). Is that considered tobacco use and do I have to report that I use tobacco when I sign up for coverage?

Yes, the Food and Drug Administration (FDA) includes e-cigarettes under the definition of tobacco. (21 C.F.R. § 1140.3; “Deeming Tobacco Products To Be Subject to the Federal Food, Drug, and Cosmetic Act,” (May 10, 2016).)
