Sweetness and nicotine form in vapes may change how people puff

NCT ID NCT05587504

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested how different e-cigarette liquids—varying in sweetness and nicotine form—affect blood nicotine levels, puffing behavior, and how people feel. Thirteen healthy adults who use cigarettes, e-cigarettes, or both took part. Researchers measured nicotine in the blood, puff volume and duration, and how quickly participants reached for their own product. The goal is to understand how liquid ingredients influence use, which could inform future product design or regulation.

What this could lead to

If successful, this could help design e-liquids that are less addictive or more satisfying for smokers switching from cigarettes.

What could go wrong

This is a very small, early-stage study with only 13 participants, so results may not apply to the general population. It does not test long-term health effects.
