Sure, glucose is a drug. There's a lot of overlap between foods, supplements, and drugs, and for the most part the distinction is created by bureaucrats at the FDA. My favorite example of something that is simultaneously a food, drug, and supplement is the Seville orange. http://en.wikipedia.org/wiki/Bitter_orange http://en.wikipedia.org/wiki/Bitter_orange The bitter orange is delicious with stronger orange flavor than a normal orange, particularly in the peel. Most commercially used "natural orange flavor" is derived from bitter orange peels. The bitter orange contains a powerful set of ephedra-like substances, which are quite powerfully mind altering. A single bitter orange is actually uncomfortably stimulating for most people, in the sense that people have enough of a sense for this kind of thing that they stop eating before they consume an entire orange. But even though sour orange extract is regulated as a supplement, it works as a powerful drug, and an unusually dangerous one at that. It still grows on trees and is very delicious and perhaps available blended in a $15 cocktail near you. Most bartenders don't realize they are adding a stimulant to a drink when they add Seville orange.
