Personal preferences keep things interesting. Passing around any doob, blunt, bowl, whatever, is kind of dirty. Ever notice that people with a cold or worse never say they probably shouldn't hit that since they are sick, and will get everyone else sick? No, cause they never bow out, and just pass around whatever illness they're carrying that week. Nasty.
But I seriously can't understand why someone would ever mix tobacco with cannabis or hash...why? Becuase it makes them happy, so more power to you, you strange ass freaks. LOL.
