i roll my own, and i'll say

1. oh, it'll give you cancer no doubt, not "safe". whether it's "more safe" than most cigs, probably; all RYO tobacco contains few or no additives, but i wouldn't think of it that way; as far as i know, smoking organic, perfect tobacco leaves will give you cancer; but i like to avoid all the additives anyway: summary: it's not safe, you will have a very highly increased likelihood of cancer

2. my suggestions for RYO: mclintock red and the stokebye versions; american spirit isn't great, pretty harsh, but it is completely additive free

i like hemp rolling papers (and we should all support hemp farmers, it's important for legilization)
