Lately Ive been smoking incense, that my friends I and bought at a small smoke shop. Some of it is a fairly mild high. But I recently smoked some that knocked me on my ass. It had a similiar affect of LSD. I'm all about trying new brands and flavors, just keep in mind to becareful what you ask for. "Voodoo spice" is mild and will last a few hours, "pulse" is alittle more potant, and lasts about two hours. "IJA Rush" is the shit that you might want to becareful of. I've done a little research but really havent come up with much as far as whats all in the incense. I have had friends who have had drug tests and have pasted.
