Two cases of khat-induced psychosis and two of psilocybin-induced psychosis are described. Khat-induced psychotic symptoms resolved without treatment within one week. One psilocybin-induced psychosis patient was treated with risperidone; the other's symptoms subsided in a few days. No somatic medical complications occurred. The paper stresses adequate psychiatric diagnosis and treatment, negative social consequences of drug use, and the need to distinguish these from functional psychoses, especially in patients with psychiatric comorbidity.
