I used to go through ounces of 5x.
If smoked properly, it's like condensing a shroom/acid trip into 5 minutes.
My first time I lied down on a bed with clothes folded next to me, and hallucinated that I was a piece of merchandise being picked up by an alien at a store. I was saying over and over "I am not a product! I am not a product!" Not every time's that intense, but shit is definitely wild.
People that didn't feel anything either smoked shit leaves or smoked improperly.
