You're completely missing the point, probably intentionally. Context exists. Everyone knows medicine in general is drugs, there are also recreational drugs/narcotics. It's usually very obvious which of these someone is referring to. They are separate categories of things with separate implications. You know this of course.
The comment I initially responded to was reacting to the usage of the word "drug". And yes while there is a distinction in categories with some distinct implications, there is also a lot of commonality between them. And the reaction I was responding to indicated a strong desire to reject those commonalities.
