Can smoking marijuana prevent cancer?

ANSWER

Animal research suggests that some chemicals in marijuana work against tumor growth, which could explain why lung cancer isn’t showing up as often as scientists might expect in people who smoke it. The studies on this are in their early days, and researchers need to take a deeper look into this theory.
