Oh yes, alcohol abuse can kill you. It is a recreational substance the use of which you would not brand "abuse" because it is legal and accepted.
Re "A couple of glasses of wine is not abuse because that's what wine is for" and "Wine wasn't invented for any medicinal purpose".
Neither was cannabis, mdma (ecstacy), lsd (acid), nor most other recreational substances "invented for any medicinal purpose". In the case of cannabis and cocaine, the stuff had been around for millenia. How can any use of them be "abuse" as per your 'medicinal' rationale?
LSD, one of the most popular party drugs ever, has never had a medicinal use, and in fact is a Schedule I drug in the US, which means it has "no acceptable medical use".
You are not OK with drugs, which is fine. But you are putting forth a demonstrably wrong hypothesis on what should constitute "abuse", and that is not fine.
Abuse depends mainly on the frequency of use. Thus the concept of alcohol abuse, which should not exist according to you, because "that's what wine is for". Similarly, one can use but not abuse other recreational substances. And it makes no difference whatsoever whether they are legal or controlled or illegal in the particular country one chooses to party in.
