Well that's why pretty much every psychoactive drug has a warning for people with mental "illness" like that. Stimulants apparently can contribute to psychosis. OTOH, I've known people that get prescribed amphetamines like mad because they're too tired out from all the anti-psychotics and mood-stabilizers. Seems a bit counterproductive.

Mania can be happy. Or at least a terrible funfuck of a ride while it lasts. At least for the person experiencing it. If they don't have to deal with all the consequences.
