NCT ID NCT03721822
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study uses a radioactive tracer called [18F]NOS to measure lung inflammation in 100 people who vape nicotine, vape cannabis, smoke cigarettes, or don't smoke at all. Participants get one PET/CT scan to compare inflammation levels between groups. The goal is to better understand how different smoking and vaping habits affect the lungs.

What this could lead to
