I'm not sure you can really say "addiction issues" are equivalent to "mental health issues."
There's definitely overlap (a lot of it) but I've been close enough to both populations to know the terms are not at all synonymous.
I don't know Lamar at all, but from very afar his issues strike me far more as "addiction issues."
I think I understand your perspective, if you mean the two don't necessary need to coexist. Technically though, substance abuse disorder is in the DSM 5.
Well yeah. The DSM 5 will some day have all sorts of stuff in it because stuff has to be billed for and they want insurance to pay. But someone who goes to a party, does heroin for fun, and gets addicted can't possibly be compared to someone with schizoaffective disorder type paranoid, comorbid with Munchusen's by proxy.
Some symptoms might be the same. There might be a loss of functionality. But a person going through detox and getting clean is not at all the same thing as someone that will need zyprexa the rest of their life and also need therapy to teach themselves some reality testing.
I think Lamar is probably more similar to the drug partier. Maybe I just think that because....idk...the recent video is of him at a night club. Probably partying.
