Actually, they're different things. You can have psychotic symptoms that include hallucinations, obviously, and delusions and ideas outside of the reality. That can actually occur in a lot of different kinds of circumstances, such as when you're severely depressed or when you have schizophrenia or a very severe psychotic disorder that is a more long-term disorder, but also when you're exposed to certain substances that can induce psychotic symptoms, such as, actually, cannabis, or cocaine, or a lot of other different drugs.
