NCT ID NCT05707871

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This early-phase study is testing whether cigarettes with very low nicotine content cause less strain on the heart compared to regular cigarettes. Researchers will measure heart rate and heart rate variability in 49 daily and non-daily smokers after smoking different types of research cigarettes. The goal is to gather basic evidence on cardiovascular effects, which could guide future tobacco policies.
