I suffer from substance-induced psychosis and taking medicines. Is this condition permanent?

thank you for taking help from a psychiatrist. I can understand your concern about it.

your illness will be under control on medications. let me explain you in simple language. When a patient is suffering from diabetes, the doctor needs to control or manage sugar level. To control sugar, the patient has to do diet and excites or medication or insulin, but important is to control sugar level. if the patient sugar level is under control with the only diet then, no need to take medication or insulin. if patient sugar not under control then patient need to either take medication or insulin.

Same way, if your thought process or behaviour will stay under control without medication in future, then you do not need to take medication. but if your thought process or behaviour does not stay under control then you have to go for medications. As you were on high dose but now on a low dose. so you may take off your medication but it is not sure that you will not need medication at all in future. it may be possible that you may not need, but not sure about it. I hope that you get your answer. please let me know if you want some help. thank you
