That depends actually. For all info on ingesting SanPedro, http://www.a1b2c3.com/drugs/mes05.htm

Traditional preparation of San Pedro is as follows: We are assuming your cactus is about 3" in diameter. Remove spines. Finely chop up about 6-12 inches or 1-2 pounds fresh (I've used a blender--but don't totally liquefy it for this method), depending on how deep you wish to journey.....
