Hmmmmm... I would imagine it's more down to personality and life issues. There's been plenty of documented cases of placid people who have had abuse in their life get angry/abusive/self harm with whatever they have taken.
I know a few drug users that seem quite nice and relaxed people, so it's not all cut and dried.
My fella takes steroids, for bodybuilding, and there's always been the popular misconception of, as they call it, 'roid rage'. Never the case with him; he's the nicest, calmest, sweetest bodybuilder (?!?) you'd care to meet.
Long story short...I'd imagine it'll depend on the individual.
😘
