Well, I once got some free Anadenanthera Colubrina seeds once when I ordered some salvia. I also couldn't find calcinated lime at the time. So, I ended up getting some snail shells, bashed them up with a rock, then a hammer and reduced them to a fine powder. I burned the powder with a small hand-held blowtorch lighter. Then fried the seeds until the shells popped open, smashed those up and mixed the seed powder and the um, snail powder. :lol: I packed all of the the powder into a tube and held it up and insufflated it. I really don't recommend doing this unless you're a masochist who's interested in the whole pain tolerance aspect of Yopo. It felt kind of like getting hit in the head with a baseball bat while simultaneously getting hydrochloric acid poured into my nasal cavity. I felt like my head was going to burst and got extremely nauseous. I ran to the bathroom and vomited violently due to the intense pain. After vomiting I looked in the mirror and noticed that my skin was purple. (not sure if this was a hallucination or some kind of drastic blood pressure change) Then I looked at the floor and saw the tiles warp and undulate. There were neon colors forming lines and shapes in some places. The wallpaper in the bathroom was "breathing." After a minute or two I had to sit down because the pain was so great. I closed my eyes and saw a ring of red, yellow, and orange triangles and other shapes that were moving at an incredible speed. The ring make a very fast Fizzling, clicking, buzzing type sound. The ring approached me and the sound had a doppler effect as i went through it. I ended up in a place I couldn't even begin to describe, and I only vaguely remember it. When I returned, I was lying on my bathroom floor. In all I'd say it was an experience worth having. Just beware of the extreme pain involved if you decide to try it. (I suspect that using ground up snail shells could have contributed to the intensity of the pain I experianced)
