Anyone take partial to, or have "success" with any (legal) herbal smoking blends?

I guess I'm talking about both the herbal smoking blends that are smoked as a cigarette alternative, to smoke just to smoke something which may or may not produce a mild effect, as well as the smoking blends that are actually psychoactivelly effective.

From doing a quick search here, the only ones mentioned here and have been effective are a BBB blend (k2 citron & blonde), and the whole Spice thing - Spice Gold, Spice Diamond, Spike99, Chillin XXX, etc. (The spice blends aren't legal everywhere).

However, some of the Spice mixtures (Diamond, Spike99, Chillin XXX) contain a THC agonist, JWH-018, which causes the red eyes that I'm SO fond of.. Although it's not my first choice that I'd want to try, I'm still curious: apparently that THC agonist doesn't show up on drug tests - Anyone know if it still stays in your body for a long period of time?

Anyone recommend any other blends?

I used to do blends like that doesn't feel as natural though. I'd assume the length they stay in the body is the same,or very close to MJ since they are synthetic cannabinoids.

SWIM enjoyed a blend named "zohai" better than spice. But for the prize of lungs irritation, SWIM prefer bufotenine anyway
