Compared to opium and alcohol where consumption dates back thousands of years.
Even today, we can find mostly older people that refuse to call themselves drug users and literally insult "other type of drug" users despite literally being one and consuming a drug on a daily basis.
It doesn’t seem especially useful to lump everyone from coffee drinkers to people using antibiotics to people shooting up fentanyl all together, so I don’t really see the point in insisting on such a literal use of the the term.
It's important to insist so people really understand that the damage is as bad as "drugs" (even worse in many cases) and that would allow to start having wine and spirit bottles and so-on at least have to deadly labels like cigarettes, which might make people slow down their consumption.
