“The distinction between what is considered a food (something that your body wants or needs in order to function optimally) or a drug (something that your brain wants or needs in order to function optimally) is becoming increasingly difficult to define. Indeed, the routine use of some substances, such as stimulants and depressants, is so universal that most of us do not even consider them to be drugs, but, rather, actual food. Is coffee, tea, tobacco, alcohol, cocoa, or marijuana a nutrient or a drug? In truth, anything you take into your body should be considered a drug, whether it’s obviously nutritious or not.”
