The world’s most common psychoactive drug is not what you might think. After hearing the words “psychoactive” and “drug” most people immediately think of illegal substances and hippies from the 1960’s. But what you might not realize is that you probably are addicted to a psychoactive substance that you consume every morning: coffee. And in coffee, you’ll find the drug affectionately known as caffeine (yes, even most decaffeinated varieties contain some caffeine).
