In my personal experience, if you took the prescribed dosage of Adderall, Ritalin, you might be fine.
I believe Strattera is the non controlled substance version that came out because so many people were abusing the controlled substance stimulants; the amphetamine pills.
I believe pdocs are much more likely to try a non amphetamine medication (Strattera being one), than a amphetamine medication.
When abused, the amphetamine medication, can cause psychosis as well as other significant problems.
When you are schizophrenic, you already have psychosis to deal with, without the amphetamine (controlled substance) medication.
Like I said; you may be able to take the amphetamine medication without psychosis, with schizophrenia, if it’s not abused; but I’m not sure how the population, or the person struggling with schizophrenia, might do.
I’m also not sure of how a person might do when you mix a AP with a amphetamine.
