Tinker, tailor, soldier, spy…or die, if you bite into too several cherry stones. Or apricot, plum or peach pits. They contain chemical compound, that is thus toxic that a mere zero.1 grams has the potential to kill one0|a ten} stone (150 pound) person. As a cherry pit contains around zero.17 grams of cyanide, ingesting only 1 or 2 crushed stones might kill you. the number of cyanide per cherry stone varies, thus a dose might be over only 1 stone, however why take the risk?
