People have been using caffeine in one form or another for thousands of years. And for at least a century, people have been fretting about what it does to our health and our moral condition. This episode dives into the history and significance of the most widely used psychoactive drug on earth.

"People were using caffeine quite some time ago. They were growing it, sometimes using the cacao beans themselve as form of currency and in some cases it was even used in rituals of human sacrifice" - Murray Carpenter
