New drugs ARE coming from that. Or did you not bother to read the article?
Just about any drug will be able to be said to be similar to another in some way in effects, that is the shared purpose of all of them, science will create it’s own new drugs, just like this one in the article, of course the media will always compare it to something in the past.
Drug legalization is about all drugs, current and future, and libertarianism is about unlimited marketing and advertising of them.
