There actually is no legal basis to call something tobacco that doesn't have tobacco in it. Nicotine is a drug. Not a medicine but a drug.
Nicotine is just a combination of molecules or molecular compounds arranged and combined in a certain way, like pretty much everything else we ingest.
Those things can be good, bad, benign, or any and all of the above.
Milk is, for instance, essentially a collection of chemical compounds.
Everything we ingest has an effect on the body.
Defining something as a "drug" just benefits Big Pharma.
The key is finding out what level of a given substance is good, bad, benign, or whatever.
And generally speaking, the idea that moderation is the key is often a good bet.
Even alcohol, in moderation, can supposedly be good for you.
But determining what constitutes moderation depends on the "toxicity" of that particular substance, and it's effects on the body.
I guess that is a lot of words to say that everything is what it is, but there is not really anything "special" about any of it when you get right down to it.
Classification of substances is often a legal and moral endeavor, and our bodies don't care about such classifications.
I don't know if any of that made any sense, but I didn't get much sleep last night.
