Check it out, that stuff just triggers the same receptors as marijuana. It's synthetic spray that is pretty much thc and they put it on that stuff. don't smoke too much because the material it's on is hazardous. You can order the spray online. but I've smoked quite a bit of spice/k2, it's pretty good substitute, same efffects as weed. but the 1st time you smoke it, it's really strong like it's the 1st time you've smoked weed. then every time after it's just like an average high.
