They found that people who smoked MJ had less of a chance of developing lung cancer than people who had never smoked anything in their lives...

Pretty nuts... But they are saying that MJ has an anti-tumour component built into it. They say that even if you smoke MJ with tobacco this anti-tumour effect nulls the damage somehow.

I don't know how much of this is true, I'm just reporting what I have been hearing.

Maybe check it out if you like. If it is true you can vape your asses off and have less chance of getting lung cancer than the guy who owns Marlboro (cos I bet he doesn't smoke the stuff!)
