A case of procyclidine abuse is described in which the clinical presentation was indistinguishable from mania. The patient was a long-standing poly-drug abuser and was obtaining the drugs from medical sources. Controlled exposure on the ward to drugs of abuse, including a double-blind comparison with placebo, confirmed that procyclidine caused a manic response in this patient.
