If a drug has a half-life of, say, 16 hours, how does the concentration in the body reach zero at some point?

Half life is a bulk statistical property, it doesn’t really count when you’re down to just a tiny actual number of molecules.
The stragglers have some percentage chance of running into a metabolizing enzyme or decaying per hour, and eventually they’re all gonna get busted.
Some lucky stragglers may evade capture/degradation for many half lives though, just like you can theoretically flip ten coins and get ten heads.
