Definitely nen888 and jamie, hopefully nothing in my post implied otherwise. Below I have attached an interesting article explaining how it is not solely genetic though and how stresses on the brain can induce a 'minorly effected person' to become more fully effected by the 'syndrome'. However short-term psychosis has definitely been noticed, whereas chronic is more rare and probably harder to catalog in a research paper due to the times the data are taken.

@Chaotic method - I wouldn't say that she should take psychedelics as this is generally not recommended for bipolar persons or schizophrenics. For bipolar people it is known to induce mania which can be life threatening and dangerous for the person and those around the person in some rare cases. Again this depends on the severity of bipolar and countless other factors. If she is medicated most medications will interfere with the actions of psychedelics anyways.

I know they did give LSD to schizophrenic children in a study in I think the 1970's(can't find it now). The kids neither improved nor significantly became worse to my understanding. For me, it can help or make things worse. The day or so after is usually fine but it's a role of the dice as to whether the following week will be cluttered with irrational life-stunting paranoia or easiness. Even with small doses.
