SWIM did that one time. He smoked 30 mg of 5-MeO-DMT in one shot thinking it was DMT. It was probably the single most frightening experience of SWIM's life. Fortunately 5-MeO-DMT doesn’t last that long. SWIM would never take that much on purpose. There was nothing in the experience that was positive. It was like being made temporarily insane. Nothing made sense. It was complete mental chaos, with no visions to make it even worth while. A terrible, terrible experience. It was like putting SWIM’s brain in a blender. Complete madness for 10 minutes and then thankful it came to an end. It’s nothing “psychedelic” at all at that does. Your brain is so fucked up that nothing makes sense, so any “psychedelic” effect would not even be noticed. It’s complete “mind fuck” and I cannot imagine anyone liking it at all at that dose, but apparently some people do!
