title: Cough mixture induced psychosis.
abstract: Cough mixture is the third most commonly abused substance in Hong Kong. Over the last two years, ten cases of cough mixture-induced psychosis were admitted to a University hospital. All of them were clinically indistinguishable from paranoid schizophrenia, but the psychotic symptoms often resolved promptly with the cessation of cough mixture use or a small dose of haloperidol. A representative case is described. The possible underlying aetiological mechanism and the treatment principle are discussed.
