whats the difference between DIP and SZ?

I went in and the lady told me i have psychosis, but she doesnt know if its drug induced or not so im going in for diagnosis soon, but my question is whatare the key differences between drug induced psychosis and sz?

my guess is pretty much the only difference is the label they slap on it. And maybe the DIP goes away after a while. I don't know much about it really.
