hair and smoking herb questions

[hoveringsombrero]

someone tell me please quite a while ago i found a few sites with lists of legal smoking herbs, just plain lists, it's name, if it's legal, and a description

this time i'm looking again and i find all sorts of cool sites selling all sorts of legal herbal smoking mixes, very spiffy but i'm looking for just an informative what's legal and what's smokeable list

anyone know?
