First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how nicotine is absorbed and affects the body when using a standardized research e-cigarette compared to a person's usual brand e-cigarette. Thirty-two regular e-cigarette users participated in a crossover study where they used both types. Researchers measured nicotine levels in the blood, puffing patterns, and feelings of satisfaction or withdrawal. The goal was to see if the research e-cigarette can be a reliable tool for future studies.
