Being high makes people superficially more like Type 9 (relaxed state) or at the worst like a phobic Type 6 (anxious state).

Anti-depressants seem to also induce a "Type 9-like narcotic effect", whereby the individual experiences a "mellowing down" of all emotions – the bad and the good. ;p

So if you or someone else is high a lot and/or on anti depressants, you likely could (mis)type yourself or that someone else as Type 9 core without necessarily being so.
