Summary
This study is investigating how common cannabis use is among lung cancer patients under 60 and whether it is linked to more aggressive tumors. Researchers will collect blood and hair samples from 150 participants across three French hospitals. The goal is to better understand if cannabis plays a role in lung cancer development and progression, especially in younger people.
