Scratch beneath the surface of a coffee bean, a red pepper flake, a poppy seed, a mold spore, a foxglove leaf, a magic-mushroom cap, a marijuana bud, or an apple seed, and we find a bevy of strange chemicals. We use these to greet our days (caffeine), titillate our tongues (capsaicin), recover from surgery (opioids), cure infections (penicillin), mend our hearts (digoxin), bend our minds (psilocybin), calm our nerves (CBD), and even kill our enemies (cyanide). But why do plants and fungi produce such chemicals? And how did we come to use and abuse some of them?
