With alcohol, most people are dishonest about it, most don't call it a drug which is quite worrisome and people addicted to that drug don't even consider themselves drug addicts, there has been such a lobby in communication around the separation of "Drugs" and "Alcohol" and people have fell for it hard. Literal propaganda :/
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.
