Well, duh! They ARE tobacco! And tobacco causes cancer. Orangeman, the reason your lungs are "happier" with blunts is that tobacco paralyzes your cilia (pronounced silly-ah They are little "hairs" in your lungs that clean smoke and pollution particles out of your lungs). When the cilia are knocked out, they can't work, so all the tobacco crud is left in your lungs where it will eventually cause cancer. Pot smoke does not paralyze the cilia. Granny:stoned:
