A 28-year-old patient with schizoaffective disorder is admitted involuntarily after threatening to jump from a bridge. After 48 hours of treatment with an antipsychotic, he is calmer but continues to refuse medication, saying, "I don't need it. I'm fine now." He demonstrates understanding of his diagnosis and the proposed medication, acknowledges that he was in danger, but believes he no longer needs medication because he feels better. Does he have the right to refuse?
