Caffeine is psychoactive at doses below 20 mg. For many people, 10 mg or less. That is a couple sips of coffee. Switching from coffee to tea or decaf is not quitting caffeine. Roland Griffiths of Johns Hopkins — one of the leading caffeine researchers in the world — found that caffeine is behaviorally active at doses far lower than anyone previously knew. His exact words: “One of the interesting things that we showed in the course of that research is that caffeine is behaviorally active at doses far lower than anyone ever knew previously. Many people can detect the effects of caffeine at doses of less than 20 milligrams, and many 10 or less milligrams. So a couple of sips of coffee can produce reliable, detectable, subjective effects. And these are really rigorous blinded studies.” This is why the common alternatives don’t get you to zero. Black tea and green tea contain caffeine. So does decaf. Stephen Cherniske — biochemist, author of Caffeine Blues — writes that a 12-ounce cup of decaf can still contain at least 10 mg, and sometimes more. This is not theoretical. A friend told me he had quit coffee and didn’t notice much difference. I asked what he was drinking instead. “Tea.” “What kind?” “Black tea. Green tea.” I was like: “Bro, you don’t even know what a caffeine-free state feels like.” If you want to know what your real state of consciousness feels like without caffeine, you have to go to zero. For me, that has meant organic rooibos tea — no caffeine, still contains polyphenols. I also drink herbal teas like mint or fruit tea, or just mineral water.
