I guess unless you want to use the broad definition of a 'drug' which is something that has an effect when introduced to your body which many things could fall under.
You're oversimplifying. Its not a broad definition at all, its the correct definition.
When you take something which occurs naturally and use synthetic processes to isolate the compound and then introduce them into a human being for the sole purpose of causing a desired reaction within the human body its called a drug.
Eating red meat or drinking milk doesn't fall under the category of doping, these are "natural processes". Coffee isnt a drug, the caffeine it contains is. however there are other things in coffee which brings it into the "food" category. If you isolated the caffeine compound and then administered it to someone - its a drug.
Quit while you're ahead.
