Seeing as how this is the hill you seem willing to die on, you need to go back and realize I never said either usage was incorrect. My issue is the ambiguity of the word now-- "vape" is an umbrella term that doesn't really specify what you mean now.
I don't harbor any kind of possessiveness about the word, I just wish the subculture's LANGUAGE WOULD EVOLVE more specific terms to avoid the ambiguity and unnecessary explanation. I don't understand why you seem so up in arms and ready to defend something that I'm not really leading an attack on. It's like you entered a conversation as if it were a debate, and now you feel like you have to defend your position against an imaginary opponent.
EDIT: And just as a fwiw, riding bicycles vs. riding horses (vs. motorcycles) is a perfect example! See, people realized that an ambiguity grew out of the word "riding" with the development of personal transportation technology. Never fear, though! Language evolved! It found a way to discern the difference with a single word! Now, you can just say you're cycling if you're referring to a bicycle and a well-informed person will instantly know the exact distinction you've just made. As a result of the more descriptive term, "riding" has become more associated with motorcycles, to the point where a person talking about bicycles now almost invariably says "riding bikes" if they refer to it as riding. Horses? Can't really speak to those, no personal experience. I'm sure a quick google search would find a specific term for riding horseback, though.
And the best part? None of this is really problematic! It might be slightly irritating in the middle of a confusing moment due to ambiguous word choice, but language and conversation still move on. Kind of.... kind of exactly what I've been saying about the application of the word "vape" to multiple types of ingestion.
*EXTRA CREDIT QUESTION: Why is it that we ride motorcycles and bikes but we drive cars?
