My understanding is that manic episodes are common when rapid removal from prolonged, extended drug use of synthetic stimulants. I assumed that since he was currently on the run that he would be without drugs since he chose to flee.
Oh I see. Alright well my understanding is that if you've had one or more manic episodes then you have bipolar disorder. I can see how coming off drugs could trigger a manic episode in somebody who was bipolar, even if it was their first such experience. However, assuming he's not bipolar, coming off drugs can still induce all sorts of sketchy, erratic, paranoid behaviour. On the other hand, he could have taken some with him... at any rate, the man needs a hospital and some lawyers.
