E-cigarette use was assessed with the item: The next questions are about vaping products or vapes. You may also know them as e-cigarettes. They can contain nicotine and/or flavors. Some common brands are JUUL, Suorin, and Puff Bar. Please do NOT include vaping marijuana, THC and CBD when answering these questions. When did you last vape, even one time?

Non-Hispanic other includes those who identified as Native Hawaiian or other Pacific Islander, those who identified as biracial and multiracial, and those who selected the “other” response option to the race survey question.

Bold indicates significant relative risk ratios (RRR) and p-values (α = .05). Model also controlled for wave of data collection.

NH = Non-Hispanic.
