I'm sorry for your frustration, please accept that it often takes people diagnosed with schizophrenia years to accept their illness.
I am schizophrenic, and I have gone off my medication, and subsequently started to hallucinate, and struggle with delusional thinking.
The medication is no walk in the park, it can be very sedating, and cause weight gain, plus you are not supposed to drink with it.
The biggest challenge to being schizophrenic can be accepting that you are schizophrenic.
My suggestion to you is to try to make your brother feel that he is not some kind of "other" as a schizophrenic, that it is merely a disease that has treatment. Try not to let him think that it is something that a person should fear, or be frightened off. That it is not something that someone should be scared of talking about.
Often I think people with schizophrenia want to think that they can beat the nasty disease to prove that there is nothing wrong with them.
This could be hidden in a lot of other phrases and actions but deep down I think people with schizophrenia don't want to allow themselves to be thought of as "other", even how they see themselves.
Try to find something your brother is interested in, or something he has been motivated by in the past and perhaps he can become motivated by things. I think this might prepare him to get on a regular medication schedule.
This is just based on personal insight, a doctor may be a better source on this, but those are things you might try with him.

Somehow he had stopped taking all those when he was under medication. But now after stopped having medicine he is taking all those drugs
again.
Try perhaps to give him cigars as an alternative to marijuana. I know that doesn't work for everyone, but it might be easier for him.
