The lethal dose of caffeine in adult humans is approximately 10 grams, while the lethal dose of theobromine (the main psychoactive chemical in chocolate, nearly identical structurally to caffeine, with similar effects) in humans is 75 grams (this is much lower in most animals, which is why you should never give chocolate to your pets). This can motivate a rough heuristic of 7.5 mg theobromine is roughly equal to 1 mg caffeine, and 750 mg theobromine is equivalent to one cup of coffee.
Therefore, to replace coffee with cocoa or chocolate, 6 spoons of unsweetened cocoa powder should replace a cup of coffee. 11 cups of hot chocolate (that’s a lot) or 2 bars of dark chocolate should also work.
