This is not accurate in what I see around me.
Alcohol far less common among young people than it used to be.
Cocaine and MDMA is flourishing.
Ritalin like drugs is out there as well but I dont have much inside inot how common it is.
That is a tiny tiny sample compared to the study so it does not in any way say that the study is wrong. It is just what I myself see and hear around me. (and what the police see a lot of )
