Please see the Universe tab for changes in the universe over time. Beginning in 2015, "pipe" was defined as "regular pipes, water pipes, or hookahs" that were filled with tobacco. Prior to 2015, "pipe" was person defined.

The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
