       | need to eat several hands full to poison yourself. And since it
       | doesn't bioaccumulate, eating tiny bits is probably okay.

           | A child could die with 5-6 whole bitter almonds, but they are
           | really, really bitter so it's not that easy to accidentally
           | do that.

           | 
           | On more than one occasion, I ate a box or two of those, so
           | many that I had painful bellyaches and worse. It may not have
           | been cyanide, but it was an instructive childhood lesson in
           | "too much of a good thing".
           | 
           | It's scary to think how much knowledge of poisons was in our
           | home with my father's profession, and mother's hobby of
           | murder mysteries. When the 1982 adulteration scandal hit the
           | news, I honestly had mixed feelings about the message it sent
           | to consumers.

       | "Much literature has historically claimed that hydrogen cyanide

       | smell of household almond essence is due to benzaldehyde, which
       | is released along with hydrogen cyanide from the breakdown of
       | amygdalin present in some plant seeds, and thus is often mistaken
       | for it.[12][13] In an experiment to test what hydrogen cyanide
       | smells like, the chemistry Youtuber NileRed described the smell
       | as "not at all like an almond" but like "weak bleach or chlorine"
       | or "swimming pools".[14]"
