A single cherry contains 0.17 grams of cyanide per each gram of seed. So, depending on the size of the pit, it will take a lot of freshly-ground cherry seeds (approximately 588) to give you a lethal dose.
LOL! I feel like some thing else would kill me before the cherry pits! If you have ever eaten many cherries you will know what I’m talking about! I love your photo and the shallow DOF
