Well... the standard answer given here to this question is:

They are different legal plants that have different effects. There are MANY legal herbs other than marijuana that can kick your butt. Some are wild dagga, cannabacae, avena sativa, sinnuchi, wild lettuce, wormwood, damiana, etc. Herbal Smoke Shop specializes in hybrid buds consisting of a # of different exotic herbs and botanicals. They are definetly great smokes, just are not marijuana. They are worth trying and if you think you are buying pot, than wake up. They are called the herbal smoke shop. Their bud is good, but it is legal herbs. They clearly explain this about 1000 times on their website. You will not fail a piss test. You cannot get arrested for smoking them. You can order them online legally. They are much cheaper than real bud, and they do work, just differently. I recommend you give them a shot as long as you understand they are legal exotic herbal smokes, not weed. They are still extremely effective, just different than pot."
Anyway, talking about other substances than weed is not allowed in this forums, so i think it also applies to legal buds.
