Cannabis use and risk of lung cancer : a case–control study

(Disponible en anglais seulement.)

This New Zealand case-control study reveals lung cancer risk increased 8% for each joint year of marijuana use, after adjusting for confounding variables along with tobacco use, and increased 7% for each pack year of tobacco use, after adjusting for confounding variables including marijuana use. Findings suggest lasting use of marijuana increases the probability of lung cancer among young adults.

Comment: This is an issue that doesn't generally occur to most people, nice to see it brought to the foreground.
