pretty sure they cause cancer... but honestly unless your smoking like 10 blunts a day I doubt you will get cancer... of course... these numbers are not scientific and my proof is not science based at all. All blunts will cause cancer... look at the boxes on the swishers... they have a warning on them...

Eventually I will limit my blunts when I get my PHX! HOLLA! but yeah... I'd watch out... cancer is no joke.
