It's also called devils weed, and for a good reason too. I've heard about people mega freaking over seeing millions of spiders attacking them, and I heard about a friend of a friend that he was pissing in a public urinal and started talking to this guy, and went for 20 minutes, and when he left, he realized that the guy was an illusion.
you can also drink it as a tea, the effects are supposed to be better like that.

I'd persoanlly stay away from it all around man.
