Summary

This study compares two smoking cessation programs for people undergoing lung cancer screening. About 1,188 participants will either receive phone counseling and nicotine replacement from a health system or be referred to a quitline. The goal is to see which approach leads to more people quitting smoking and staying smoke-free.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
phone-based tobacco treatment and nicotine replacement therapy (patches and lozenges)
What this could lead to
If successful, this could show a more effective way to help smokers quit during lung cancer screening, reducing their cancer risk.
What could go wrong
This is a large trial, but quitting smoking is very hard, and the extra support may not lead to lasting abstinence. Results may not apply to all populations.
