Meh it's alright. I don't think it's safe, it's too new to say if it'll do anyhting long term and not much is known. I'll tell you the high is mildly halucenogenic at times, but can be compared to a frantic, nowhere NEAR as calm, panicking weed high. It is mildy euphoric though. As with all things legal (cigarettes, alcohol etc.) I just don't think it could possibly be good for you. They also have to write "not for human consumption" somewhere on the packaging to make it legal, but that also gives them the right to put whatever they want into it, even if it's killing you. The stuff alsosmells good (like incencse) when you burn it, so I think it's got to be bad for you in that, in order to actually make the stuff pass as incense, they add even MORe probably harmful chemicals. Stick to weed though, it's better, cheaper, better tasting, the high is calmer, and weed isn't really bad for you.
