Study on the Effects of Environment and Cannabis Use in Adults with Lung Cancer Aged 18 to 59

What this Trial Is About

Researchers are investigating the relationship between cannabis use and lung cancer, focusing on patients aged 18 to 59 years treated for primary lung cancer. Cannabis is widely consumed and has recognized neuro-psychic effects, but its impact on lung cancer development remains uncertain. Previous studies suggest cannabis smoke contains more carcinogens than tobacco smoke, and clinical observations have raised concerns about cannabis possibly contributing to more aggressive lung cancers in young patients who are heavy users. The study categorizes participants into three groups cannabis smokers who also use tobacco, tobacco-only smokers, and non-smokers. Participants will provide blood and hair samples to support the research. This study is non-randomized and does not involve blinding. The primary measure is the percentage of patients who are active cannabis smokers, defined as smoking at least 10 joints per month for at least one year. Participants will be monitored for cannabis use status, and researchers will collect biological samples to analyze potential differences in lung cancer profiles across groups. The study aims to understand the prevalence of cannabis smoking among lung cancer patients and its possible influence on disease characteristics. This involvement includes consenting to sample collection and data recording during their treatment period, with the research spanning multiple hospitals.
